polyamide 12 is nylon 12, and the scientific name of polyamide 12 is polydolactam. It is a semi-crystalline-crystalline thermoplastic material. The basic raw material for polymerization is butadiene. It depends on petrochemicals. Its properties are similar to those of PA11, but its crystal structure is different.
polyamide 12 is a good electrical insulator and, like other polyamides, does not affect insulation properties due to moisture. It has good impact resistance and chemical stability. Polyamide 12 has many improved varieties in terms of plasticizing properties and reinforcing properties.
The viscosity is mainly determined by humidity, temperature and storage time. It is very fluid. The shrinkage is between 0.5% and 2%, depending on the material variety, wall thickness and other process conditions.
Application range mainly includes these aspects: cable sleeves, water gauges and other commercial equipment, mechanical cams, sliding mechanisms and bearings.
Polyamide 12 has excellent mechanical properties and is easy to polymerize rapidly. After modification, the compressive strength and corrosion resistance are obviously enhanced.
Can be widely used in the production of automotive bushings, fuel tanks, bearings, gears, steering wheels, gear shift handles, pulleys, fuel hose hose assemblies, joysticks, plastic brackets, protection frames. Injection molded with polyamide 12 can also produce automotive coupling parts, bumpers, joystick covers, fenders, accelerator pedals, wheel covers, etc., as well as other complex shapes. High production efficiency and stable product size.
E M S Chemicals of Switzerland has introduced polyamide 12 and a blend of linear low-density polyethylene grafted with a blend to produce containers for various engine components such as cooling system components, fuel filters and brake fluids.
