PA12 is butadiene linear, semi-crystalline - crystalline thermoplastic material. Its characteristics and PA11 similar, but different crystal structures. Polyamide PA12 and other moisture will not affect insulation performance, it is a good electrical insulator. It has good chemical stability impact resistance. PA12 has many features and improved varieties in plasticizing characteristics of glass fiber reinforced. PA6 and PA66, and compared these materials have a lower melting point and density, with a very high moisture regain. PA12 attacked by strong oxidizing acids. PA12 viscosity depends on humidity, temperature and storage time. Its flowability. Shrinkage of between 0.5% to 2%, depending on the variety of materials, wall thickness and other process conditions PA12 scientific name polydodecalactam, also known as nylon 12. The basic raw material polymerization of butadiene, may rely on petrochemicals. Semi-crystalline - crystalline thermoplastic material. Its characteristics and PA11 similar, but different crystal structure Drying: moisture content must be below 0.1% prior to processing. If the material is exposed to the air storage, it is recommended to be dried in a 85C hot air for 4 to 5 hours. If the material is stored in a sealed container, then the temperature equilibrium after three hours can be used directly. Melting temperature: 240 ~ 300 ℃; for the general properties of the material should not exceed 310 ℃, the flame-retardant properties of the material should not exceed 270 ℃. High-speed injection molding can make good speed.
