PA12 PA12 polyamide or nylon 12 Chemical and physical properties of PA12 PA12 is a linear, semi-crystalline - crystalline thermoplastic material from butadiene. Its properties are similar to PA11, but its crystal structure is different. PA12 is a good electrical insulator and will not be affected by moisture as other polyamides. PA12 has good impact resistance mechanical and chemical stability. There are many improved varieties of PA12 in terms of plasticizing and reinforcing properties. Compared with PA6 and PA66, these materials have lower melting point and density, and have very high moisture recovery. PA12 has no resistance to strong oxidizing acids. The viscosity of PA12 depends mainly on humidity, temperature and storage time. PA12 It's very liquid. The shrinkage rate of PA12 is between 0.5% and 2%, depending on the variety of PA12 material, wall thickness and other process conditions. PA12 compounds plastic Nylon glass fiber material is a kind of composite material, adding glass fiber on the basis of the original nylon material, so that the material has the following characteristics: High temperature resistance, good dimensional stability, good toughness, good insulation, corrosion resistance, high mechanical strength.

Nylon 6 is a suitable material for injection molding. The resulting molded nylon parts possess great strength, as well as chemical and temperature resistance. When molding nylon 6, the material is sometimes injected with a specified amount of glass or carbon fibers (usually between 20% and 60%) to boost its tensile strength.

Polyamides can come in various colors including: yellow, white, and light brown. However, polyamide fibers can be dyed to any color, and solid polyamides can be surface finished with a wide variety of paint colors. 

With its unique balance of strength, barrier performance, and stability, MXD6-LGF is the ideal solution for demanding applications.

The reason behind choosing polyamide over other materials will vary for different applications. When using polyamide for electrical cable protection, it offers better performance, flexibility, and impact resistance than PVC protection. In the automotive industry, it is used because it is cheaper and lighter than metal. In machines, it is used over other materials due to its high flexibility and durability. 

PA6 & PA6-LGF Long Glass Fiber Reinforced Nylon PA6, also known as Nylon 6, is a high-performance polyamide widely used in engineering plastics, fibers, and films. It is a thermoplastic polymer with repeating amide groups (-NH-CO-) in the main chain, offering strong mechanical properties and versatile processing capabilities. What is PA6 Plastic? PA6 is an aliphatic polyamide that provides excellent strength, wear resistance, and chemical resistance to weak acids, alkalis, and certain organic solvents. Its lightweight and processable nature make it widely applied in fibers, engineering plastics, and thin films. However, the polar amide groups in PA6 easily form hydrogen bonds with water molecules, which can result in high moisture absorption, dimensional changes, and reduced impact strength in dry or low-temperature conditions. Advantages of PA6 High mechanical strength and toughness with excellent tensile and compressive properties Outstanding fatigue resistance, maintaining strength after repeated bending High softening point, heat resistant Low friction and wear-resistant surface Corrosion resistance to alkalis, salts, weak acids, oils, and most solvents Self-extinguishing, non-toxic, odorless, and good weather and biological resistance Excellent electrical insulation even in high humidity environments Lightweight, easy to dye, and easy to mold due to low melting viscosity Limitations of PA6 High moisture absorption (up to 3% when saturated) Poor light and thermal stability; prolonged high-temperature exposure may cause discoloration and surface cracking Strict injection molding requirements; trace moisture can affect product quality Dimensional stability is sensitive to thermal expansion and wall thickness variations Not resistant to strong acids or oxidizing agents; unsuitable for acid-resistant applications Why Reinforce PA6 with Long Glass Fiber? To overcome the natural limitations of PA6, long glass fiber (LGF) reinforcement is applied. PA6-LGF composites combine the lightweight, chemical, and heat resistance of PA6 with the mechanical strength and dimensional stability of long glass fibers. LGF reinforcement improves tensile, compressive, and flexural strength, reduces shrinkage, enhances fatigue resistance, and provides improved thermal and chemical stability. This makes PA6-LGF ideal for high-performance structural components. Applications of PA6-LGF PA6 reinforced with 30% long glass fiber (30% LGF) is widely used in: Power tool shells and components Engineering machinery parts Automobile structural and functional components The composite improves mechanical strength, dimensional stability, heat resistance, aging resistance, and fatigue resistance. Its fatigue strength can be up to 2.5x that of unreinforced PA6. Processing and Forming Tips for 30% PA6-LGF Shrinkage is reduced to ~0.3% compared with 1–1.5% for pure PA6. Excessive fiber content may cause surface floating fibers and poor compatibility. 30% LGF is recommended for balanced performance. Recycled material content should be kept below 25% to avoid color and mechanical property degradation. Gradual cooling after molding prevents warping due to fiber orientation during injection molding. Mold design, gate position, and temperature control are critical. Customers & Staffs Certificates

Nylon 66 material for machining has improved temperature resistance and lower rates of water absorption when compared to standard nylon 6.

PA6 long carbon fiber reinforced material offers high strength, excellent impact resistance, and lightweight properties. It provides outstanding dimensional stability and fatigue resistance, making it ideal for automotive and industrial applications. Suitable for replacing metal components to achieve weight reduction and enhanced performance.

PA6-LGF PA6 modified plastics use pure PA6 as the matrix and enhance internal and external properties through blending, filling, strengthening, copolymerization, crosslinking, and other methods. They account for approximately 15% of PA6 applications. Long glass fiber content ranges from 20%–60%, adjusted according to product requirements, providing high strength, superior heat resistance, good impact resistance, and lightweight alternatives to certain metals. Common applications include power tool shells, garden tools, gears, sports equipment, and automotive parts. Other Specifications of PA6-LGF Flame Retardant PA6: PA6 is naturally flammable, but adding flame retardants changes its combustion properties. Mechanical mixing incorporates nitrogen, phosphorus, bromine-based, or mineral flame retardants. These materials are suitable for switches, low-voltage electrical housings, wiring terminals, and circuit breakers. Toughened PA6: Incorporating toughening agents improves low-temperature resistance, flexibility, fluidity, reduces shrinkage and water absorption, enhances impact and aging resistance. Ideal for baby carriage parts, rolling belts, line clips, and connectors. Applications Beyond daily applications, PA6 modified plastics are increasingly used in high-end fields such as rail transit, medical devices, military, and aerospace. TDS for Reference Nylon reinforced materials are made from PA6/PA66 resins with 20–60% glass fiber to increase strength. 30% fiber content is most common, but 40–50% can be used based on product requirements. Advantages of Long Glass Fiber Compounds 1. High-temperature resistance improves significantly after glass fiber reinforcement, especially for nylon plastics. 2. Shrinkage decreases and rigidity increases due to limited polymer chain movement. 3. Stress cracking is reduced and impact resistance improves. 4. Mechanical properties such as tensile, compression, and bending strength are enhanced. 5. Flame retardancy improves; most reinforced materials become self-extinguishing.
