PA12 information

Long carbon chain nylon is a nylon with amide group in the main chain repeating unit of nylon molecule, and the length of methylene group between two amide groups is more than 10. We call it as long carbon chain nylon, including nylon 11, nylon 12, etc..

PA12 is nylon 12, also known as poly(dodecalactam) and poly(laurolactam), which is a kind of long carbon chain nylon. The basic raw material for polymerization is butadiene, a semi-crystalline - crystalline thermoplastic material. Nylon 12 is the most widely used long carbon chain nylon, it has most of the general properties of nylon, in addition to low water absorption, and has high dimensional stability, high temperature resistance, corrosion resistance, good toughness, easy processing and other advantages. Compared with PA11, another long carbon chain nylon material, PA12's raw material butadiene is only one-third the price of PA11's raw material castor oil, and can be used in most scenarios instead of PA11, and has wide applications in many fields such as automotive fuel hoses, air brake hoses, submarine cables, and 3D printing.

Among long-chain nylon, PA12 has great advantages compared with other nylon materials, its advantages are the lowest water absorption, lowest density, low melting point, impact resistance, friction resistance, low temperature resistance, fuel resistance, good dimensional stability, good anti-noise effect, etc. PA12 has the properties of PA6, PA66 and polyolefin (PE, PP) at the same time, to achieve the combination of lightweight and physical and chemical properties, with performance It has the advantages of light weight and physical and chemical properties.

PA12-LCF

If the base material is compared to concrete, the fiber is like steel reinforcement, and mixing the two is like adding steel reinforcement to concrete. If there is only concrete, the castings will easily crack under external forces, but once the high-strength reinforcement is added to it and the concrete wraps it sufficiently, they will become a single unit. When the object is subjected to external forces, the rebar can withstand most of the external forces, making the structural strength of this whole very high.

Carbon fiber has many excellent properties, high axial strength and modulus of carbon fiber, low density, high specific performance, no creep, resistance to ultra-high temperature in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmittance. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance.

Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness is also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance. Therefore, carbon fiber reinforced nylon (CF/PA) composites have developed rapidly in recent years.

Frequently asked questions

1. How does thermoplastic carbon fiber composite material achieve low cost and environmental protection?

Thermoplastic carbon fiber composites are used to make parts for high-end machinery. They have excellent machinability, vacuum forming, stamping mold plasticity, and bending processability.


2. Thermoplastic carbon fiber composites are only suitable for injection molding?

From the process point of view, injection molding has a higher degree of automation compared with molding, and the raw material is not in contact with the outside world, so the product appearance quality is guaranteed, and there are no black spots, impurities, uneven colors, etc. The mechanical properties, dimensional stability and precision of the product are relatively higher. At present, Japan Toray, these carbon fiber giants in the application of carbon fiber reinforced thermoplastic composites, the main use of injection molding method, and this method is suitable for the production of complex-shaped parts and mass production. It should be noted, however, that thermoplastic carbon fiber composites using injection molding must be reinforced with short-cut or powdered carbon fibers, and this process is not applicable to continuous carbon fiber reinforced thermoplastic composites.

Compared to injection molding equipment, compression molding equipment and its mold structure are relatively simple and less expensive to manufacture. The molding equipment can be used for both thermosetting and thermoplastic resins, and in the molding of thermoplastic carbon fiber products, it is the full experience of manufacturing thermosetting carbon fiber parts. The use of molding to make thermoplastic carbon fiber composite parts, the loss of raw materials is smaller and will not cause excessive losses, and when applied to mass production, the price is better to meet market demand compared to the injection molding process.
