Material Introduction In 1935, Wallace Carothers, a scientific researcher at DuPont, and his team successfully synthesized PA66 by condensation of adipic acid and adipic diamine for the first time, and DuPont completed the commercial production of PA66 fiber in 1939. Starting in the 1950s, PA, including PA6 and PA66, was developed for the production of injection molded products to replace metal to meet the requirements of light weight and cost reduction of industrial products. At present, PA66 is the most used PA species other than PA6. PA66 Scientific name: Polyhexanediamide Abbreviation: PA66 Common name: Nylon 66  PA66 has many similarities with PA6. PA66 is also a transparent to milky white granule that can take on almost any color with the addition of a colorant (masterbatch) specific for polymers. Material properties Similar to the basic properties of PA6, PA66 also has low specific gravity, high tensile strength, wear resistance, good self-lubrication, and excellent impact toughness. In addition, because the number of hydrogen bonds in PA66 is more than in PA6, the intermolecular force of PA66 is stronger than the intermolecular force of PA6, which makes the internal structure of PA66 more compact than PA6, with better thermal properties, higher rigidity and toughness, better dimensional stability, lower water absorption, and more wear resistance. However, PA66 has a higher market price than PA6 and is not as easy to process and mold as PA6. Like PA6, PA66 can also add a certain percentage of glass fiber, carbon fiber, etc. to improve the performance and meet the application needs of different products. The following table is a PA66-LCF30 performance table produced by Xiamen LFT composite plastic company.

PA6 Information Nylon 6 (PA6) is a thermoplastic semi-crystalline polymer made of caprolactam condensation, with its high toughness, low coefficient of friction, excellent impact properties and excellent high-temperature load-bearing capacity and become one of the engineering plastics with high dosage. PA6 is mainly used in food packaging films, containers, mechanical parts, automobiles and other fields, but due to high water absorption, poor heat and light resistance, poor dimensional stability and other shortcomings limit its scope of application. Therefore, the functionalization and high performance modification of PA6 is getting more and more attention from academia and engineers, among which fiber composites are one of the main research directions. Fiber composites are composites with polymer as the continuous phase of the matrix and nano-scale fillers as the dispersed phase. Fiber-based materials, including long glass fiber (LGF) and long carbon fiber (LCF), are high-performance materials. Adding fiber materials to the resin can greatly improve the overall material properties. The use of long glass fiber compounded with PA6 can help improve the impact strength, dimensional stability and other properties of the polymer, which can significantly improve the overall performance of PA6. Long glass fiber reinforced PA6 Long fiber reinforced thermoplastic composites are reinforced thermoplastics with fiber lengths greater than 10mm, and the reinforcing fibers are mainly glass fibers, carbon fibers and other fibers. The effect can be achieved with the appropriate fiber surface treatment. The addition of fiber material to the resin can greatly improve the overall material performance. Fiber composites absorb external forces in three ways: fiber pullout, fiber breakage, and resin fracture. The increase of fiber length consumes more energy for fiber pull-out, which is beneficial to the improvement of impact strength; the end of fiber in the composite is often the initiation point of crack growth, and the small number of long fiber ends also makes the impact strength increase; the long fiber blends entangle, flip and bend each other when filling the mold, unlike the short fiber blends which are arranged in the flow direction, therefore, the long fiber blends molded products are better than the same molded parts of short fiber blends. Therefore, compared with the same molded parts of short fiber blends, the long fiber blends have higher isotropy, better straightness, less warpage, and therefore better dimensional stability; the heat deflection temperature of long fiber reinforced thermoplastics is also increased than that of short fiber blends. Therefore, long-fiber composites exhibit better performance than short-fiber composites, which can improve rigidity, compression strength, bending strength, and creep resistance. Thermoplastic composites are divided into long-fiber reinforced and short-fiber reinforced types. Product details The color and length can be customized as your needs.

Polyamide 66 Nylon is the common name for polyamide (PA), a generic term for thermoplastic resins containing repeating amide groups on the main chain of the molecule, including aliphatic polyamides, aliphatic-aromatic polyamides and aromatic polyamides. As one of the top five engineering plastics, nylon has an extremely wide range of industrial applications, mainly in automotive parts, mechanical parts, electronics and appliances, cosmetics, adhesives and packaging materials. Among them, the largest production and most widely used are aliphatic polyamides, mainly nylon 66 and nylon 6. Nylon 66 (PA66) is made by condensation of adipic acid and hexanediamine, which is a class of polyamide. Advantages: high strength, corrosion resistance, good wear resistance characteristics, and has self-lubricating, flame retardant, non-toxic environmental protection and other excellent performance. Disadvantages: poor heat resistance and acid resistance, low impact strength in dry state and low temperature, high water absorption affects the dimensional stability and electrical properties of products. Polyamide 66 filling long carbon fiber High-performance fibers are chemical fibers with high load-bearing capacity and high durability because they have a special physical or chemical structure embodied with some excellent characteristics that traditional fibers do not have, such as high temperature resistance, corrosion resistance, flame retardancy and other properties. Carbon fiber is an inorganic polymer material with carbon content higher than 90% obtained from organic fibers through carbonization and graphitization. Advantages: light weight, high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance, electrical conductivity, thermal conductivity, etc. Disadvantages: high cost, relatively difficult to infiltrate, poor transparency, etc. Carbon fiber composite materials are very useful structural materials, which are not only light, high temperature resistant, but also have high tensile strength and elastic modulus, and are indispensable materials for the manufacture of spacecraft, rockets, missiles, high-speed aircraft and large passenger aircraft. In transportation, chemical industry, metallurgy, construction and other industrial sectors, as well as sports equipment and other aspects have a wide range of applications. The density of PA66/CF composites tends to increase slightly as the content of CF increases. This is due to the fact that the density of CF is larger compared to that of PA66. The fracture surface of PA66 is smoother, while the fracture surface of PA66/CF sample is extremely rough and CF is pulled out, which indicates that the CF in the system plays a good role in bearing the load when the composite sample is subjected to external force, and this fracture is a ductile fracture, therefore, PA66/CF composite is a ductile material. With the increase of CF content, the tensile strength of PA66/CF composites increased significantly. The flexural strength and flexural modulus of PA66/CF composites are increased substantially with the increase of CF content.

Polyamide 12 PA12, nylon 12, also known as polydodecalactam and polylactam, is a long carbon chain nylon. There are non-polar methylene groups in nylon 12, and the number is large, which makes the flexibility of nylon 12 molecular chain larger; the amide group in nylon 12 is polar, and the cohesion energy is large, and it can form hydrogen bonds between molecules, which makes the arrangement of molecules more regular. Therefore, the crystallinity of nylon 12 is high, and the strength is also higher. Nylon 12 (PA12) has low water absorption, good low temperature resistance, good air tightness, excellent alkali resistance, grease performance, medium resistance to alcohols and inorganic dilute acids and aromatics, good mechanical properties and electrical properties, and is a self-extinguishing material. 1) Density The relative density of nylon 12 is only 1.01-1.03, which is the smallest among all engineering plastics, which has a certain effect on reducing the mass of the car and lowering the fuel consumption. If compared by unit volume, nylon 12 has advantages in price and performance. 2) Melting point The melting point of nylon 12 is 172-178℃, which is slightly lower than that of nylon 11, and it can fully meet the working temperature requirement of automobile fuel and air brake pipes. 3）Water absorption As we all know, the biggest drawback of nylon products is the large water absorption, and it is difficult to ensure the dimensional stability. However, due to the increase of methylene molecules in nylon 12, the influence of hydrophilic groups is greatly reduced, therefore, nylon 12 has the lowest water absorption rate among nylon products, which reduces the change of performance and size of products caused by water absorption, which makes nylon 12 have great advantages. After water absorption, the tensile strength of nylon 12 decreases very little, while nylon 66 and nylon 6 have great changes. 4) Impact strength Impact strength is an important technical index, and it is especially important for nylon 12 tubes that are often exposed to air. Nylon 12 at -20 ℃ and -40 ℃ according to the standard test, no fracture phenomenon, fully meet the requirements of use. Nylon 12 impact resistance is very good. 5）Low temperature performance Nylon 12 has the lowest brittleness temperature of -70 degrees Celsius, so it can be widely used for parts with low temperature resistance. 6) Flexibility The effect of plasticizers on the physical properties of nylon 12 is concentrated on the elastic modulus of the resin. There are three basic types of nylon 12 resins, the main difference between them is the different plasticizer content and the formation of different flexibility. As the content of plasticizer extractable components increases, the elastic modulus of the resin decreases. 7）Low abrasion and low friction properties Nylon 12 has excellent low-wear and low-friction properties and self-lubricating properties, so the frictional noise of Nylon 12 products is very low. 8）Fuel resistance In the automobile, the current use of oxygenated fuel, high aromatic fuel and alcohol mixed fuel will lead to the decomposition of many hose materials. Only nylon 11, nylon 12 and fluorocarbon elastomers have been tested for use in this environment. Under the action of motor fuels, all nylons dissolve, resulting in dimensional changes, especially in methanol-containing gasoline, where nylons containing large amounts of amide groups such as nylon 6 dissolve much more than nylons containing small amounts of amide groups such as nylon 12 %. It is found that the fuel containing 15% methanol has a great effect on nylon. 9) Resistant to zinc chloride solution Zinc chloride will appear in the environment under the car. Under certain temperature and humidity, the salt on the road reacts with galvanized steel or zinc-containing primer to form a small amount of zinc chloride. Zinc chloride is highly corrosive, but Nylon 12 is highly resistant to zinc chloride solutions. Ozone aging, UV exposure, temperature conditions, etc., can bring varying degrees of damage to parts and reduce service life. Since nylon 12 does not contain the + 2 3 2 + unsaturated double bond, which is susceptible to ozone attack, it does not suffer from ozone aging. In addition, the high crystallinity of nylon 12 and its high melting temperature make it more stable in terms of heat resistance, and the addition of heat stabilizers increases its heat resistance exponentially. When exposed to sunlight, its energy can cause the chemical bonds of organic materials to break. The bonding energy of C-H, C-O and C-N bonds in nylon 12 is so large that UV light is not enough to break them, but only the C-C bonds with smaller bonding energy; therefore, after adding appropriate anti-aging agents to the raw materials, the UV resistance of nylon 12 is excellent.
