What is PA6 plastic? polyamide (PA), usually called Nylon, is a hetero-chain polymer containing amide group (-NHCo -) in the main chain. It can be divided into aliphatic group and aromatic group. It is the earliest developed and the most used thermoplastic engineering material. Polyamide main chain contains many repeated amide group, used as a plastic called nylon, used as a synthetic fiber called nylon. A variety of different polyamides can be prepared according to the number of carbon atoms contained in binary amines and dibasic acids or amino acids. At present, there are dozens of polyamides, among which polyamide-6, polyamide-66 and polyamide-610 are the most widely used. Polyamide-6 is an aliphatic polyamide, with light weight, strong strength, wear resistance, weak acid and alkali resistance and some organic solvents, easy molding and processing and other excellent properties, widely used in fiber, engineering plastics and thin films and other fields, but PA6 molecular chain segment contains strong polarity amide groups, easy to form hydrogen bonds with water molecules, The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. Advantages of nylon 6: High mechanical strength, good toughness, high tensile and compressive strength. Outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. High softening point, heat resistant. Smooth surface, small friction coefficient, wear-resistant. Corrosion resistance, very resistant to alkali and most salts, also resistant to weak acids, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, alkaline and so on, and has good anti-aging ability. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and mildew resistance. Has excellent electrical performance, good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can work frequency insulation material, even in high humidity environment still has good electrical insulation. Light weight, easy dyeing, easy forming, because of low melting viscosity, can flow quickly. Disadvantages of Nylon 6: Easy to absorb water, water absorption, saturated water can reach more than 3%. Poor light resistance, in the long-term high temperature environment will oxidize with oxygen in the air, the color turns brown at the beginning, and the subsequent surface is broken and cracked. Injection molding technology requirements more strict, the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. Will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. Why filling Long Glass Fiber? PA6 has excellent properties such as light weight, strong strength, abrasion resistance, weak acid and alkali resistance and some organic solvents, and easy molding and processing. It is widely used in the fields of fibers, engineering plastics and films. However, the molecular chain segment of PA6 contains highly polar amide groups, which are easy to form hydrogen bonds with water molecules. The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. With the development of science and technology and the improvement of life quality, the defects in some properties of traditional PA6 materials have limited its development in some fields. In order to improve the performance of PA6 and expand its application field, PA6 should be modified. Filling enhancement modification is a common method for physical modification of PA6. It refers to the modification of PA6 by adding fillers such as glass fiber and carbon fiber into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material. What is application of PA6-LGF? Modified section of 30% long glass fiber reinforced PA6 is the ideal material for processing power tool shell, power tool parts, engineering machinery parts and automobile parts. Its mechanical properties, dimensional stability, heat resistance and aging resistance have been significantly improved. The fatigue resistance strength is 2.5 times that of unenha...

PA66 filling LGF Nylon (PA) has a series of excellent properties, such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubrication, easy processing and forming, and has become one of the thermoplastic engineering plastics widely used at home and abroad. But in the practical application, the performance requirements of nylon are different under different conditions or environment. For example, electric drill and motor shell, pump impeller, bearing, diesel engine and air conditioning fan and other parts require nylon material to have high strength, high rigidity and high dimensional stability; Because of the poor toughness of nylon at low temperature, it is necessary to toughen it. In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. The reinforced materials used for nylon are mainly glass fiber, carbon fiber, whiskers and other fibrous materials, and the glass fiber reinforced is the most widely used. The glass fiber reinforcement can obviously improve the rigidity strength and hardness of the material, and the dimensional stability and heat resistance of the material are obviously improved. Because nylon itself is not strong enough, by adding 10 to 30 percent of the fiber, to increase its strength. In particular, 30% strength is considered the most appropriate ratio. Also added to 40-50%, according to the specific requirements of different products, coupled with the appropriate formula, can be successful. Production technology of glass fiber reinforced nylon Long fiber method, that is, nylon and other components are premixed and added to the hopper, and the glass fiber from the glass fiber entrance through the screw rotation into the screw, and then mixed with nylon resin. Factors affecting the properties of glass fiber reinforced nylon Firstly, the interface bond between glass fiber and nylon resin has the most important effect on glass fiber reinforced nylon. If the combination between the two is not good, the reinforcement effect will be greatly reduced. At this time, the surface treatment of glass fiber is particularly important. Today, fiberglass manufacturers have been able to produce fiberglass models for different materials with different surface treatments for use by modified plastics manufacturers, as long as the right choice. Second, the length of glass fiber in nylon material is another major factor affecting its properties. In general, long glass fibers are superior to short glass fibers in terms of tensile strength, bending strength and modulus, and notched impact strength. At the same time, the dispersion of glass fiber in the material can not be ignored. The dispersion of glass fiber mainly depends on the appropriate shearing action of twin-screw and the kneading action of material, which involves the combination and speed of screw. The selection of screw speed is related to the content of additives such as glass fiber in the formula. For flame-retardant reinforced nylon, low speed is appropriate because the flame retardant has been decomposed by heat. In addition, processing temperature, glass fiber diameter, glass fiber type will also affect the final performance of the material, so it will not be repeated here. Glass fiber enhances the fluidity of nylon The fluidity of glass fiber reinforced nylon is poor, and problems such as high injection pressure, high injection temperature, dissatisfaction with injection molding and poor surface quality are easy to occur in the process of injection molding, which seriously affect the appearance of products and lead to a high defect rate of products. Especially in the production process of injection molding products, and can not directly add lubricant to solve the problem, can only be improved on the raw material, generally speaking, this needs to be added in the modified formula lubrication componentS. Resistance of glass fiber reinforced nylon to high temperature heat and oxygen aging In some applications such as bearings and diesel fans, glass fiber reinforced nylon often faces the problem of long time high temperature thermal and oxygen aging. Although the reinforced modification of nylon with glass fiber can moderately improve the heat resistance of nylon, it can not solve the problem well. Better results can be achieved by adding appropriate anti-thermal oxygen aging additives to the glass fiber reinforced nylon composite material, as shown in the figure above. Glass fiber enhances the weather resistance of nylon Nylon under the influence of sunlight, temperature change, wind and rain and other external conditions, there will be a series of aging phenomena such as fading, discoloration, cracking, powder and strength reduction, among which UV is the key factor to promote aging. Weather resistant nylon is currently mainly black products, that is, by adding carbon black and other ultraviolet absorption additives in nylon to solve its weather re...

But in the practical application, the performance requirements of nylon are different under different conditions or environment.

In some outdoor applications, nylon materials must be weather-resistant modification in long-term outdoor environment. PA66-LCF Long carbon fiber reinforced nylon has excellent damping properties in 3D printing and has better performance than glass fiber reinforced nylon. In the design of tools for industrial applications, traditional techniques have used aluminum or alternative metal alloys because metal components perform better and meet the requirements of the tool. In many cases, thermoplastics can meet the strength requirements of such tools, but not the rigidity requirements for performing test tasks. Carbon fiber reinforced nylon is an ideal substitute for metal. Due to the combination of the light weight of nylon and the mechanical strength and thermal properties of carbon fiber, the strength and stiffness of carbon fiber composite nylon material is significantly improved, and its mechanical strength even exceeds that of 3D-printed PEEK and PEKK. In the automobile industry, from internal and external components such as vehicle anchors and instruments to engine housing, metal parts can be replaced. As we all know, automotive carbon fiber is widely used in automobile manufacturing due to its strong thermal and mechanical properties. As a substitute for metal parts, carbon fiber reinforced nylon has a wide range of application prospects in the automobile industry, which can realize the possibility of weight reduction and design optimization, as well as environmental protection and economic advantages.

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...

Is a colorless transparent semi-crystalline thermoplastic polymer, widely used in automobiles, electronic appliances, mechanical instruments, industrial parts and other industries. What is PA66-LGF? However, due to the large absorbency of nylon itself, poor acid resistance, low impact strength of dry state and low temperature, and easy deformation after water absorption, the dimensional stability of the product is affected, so that its application range is limited to some extent. In order to improve the above shortcomings, expand its application field, and better meet the requirements of performance, people adopt a variety of methods to modify PA66 plastic, so as to improve the impact property, thermal deformation property, forming processing property and chemical corrosion resistance. Because the specific strength and Young's modulus of glass fiber (LGF) are 10~20 times larger than that of PA66, the linear expansion coefficient is about 1/20 of that of PA66, the water absorption is close to zero, and it has good heat and chemical resistance, glass fiber filling is the most commonly used enhancement modification method of PA66.

Application In addition to the above applications, in high-end fields such as rail transit, medical treatment, military industry and aerospace, nylon 6 modified plastics are used more and more widely, and PA6 modified plastics are used everywhere in daily life. TDS for reference Nylon reinforced material is made of PA6/PA66 resin as the base material and adding a certain proportion of glass fiber modification. Because nylon itself is not strong enough, by adding 20 to 60 percent of the fiber, to increase its strength. In particular, 30% strength is considered the most appropriate ratio. Also added to 40-50%, according to the specific requirements of different products, coupled with the appropriate formula, can be successful. Advantage of Long glass fiber compounds 1. After glass fiber reinforcement, glass fiber is a high temperature resistant material, therefore, the heat resistance temperature of reinforced plastics is much higher than before without glass fiber, especially nylon plastics; 2. After glass fiber reinforcement, due to the addition of glass fiber, limited the mutual movement between polymer chains of plastics, therefore, the shrinkage rate of reinforced plastics decreases a lot, rigidity is greatly improved; 3. After glass fiber reinforcement, the reinforced plastic will not stress crack, at the same time, the anti-impact performance of plastic is improved a lot; 4. After glass fiber reinforcement, glass fiber is a high strength material, which also greatly improves the strength of plastic, such as: tensile strength, compression strength, bending strength, improve a lot; 5. glass fiber reinforced after, due to the addition of glass fiber and other additives, the combustion performance of reinforced plastics decreased a lot, most of the material can not ignite, is a kind of flame retardant material.
