The scientific name of PA12 is poly(dodecalactam), also known as nylon 12. The basic raw material for its polymerization is butadiene, which can be relied on for petrochemicals. It is a semi-crystalline-crystalline thermoplastic material. Its properties are similar to those of PA11, but the crystal structure is different. PA12 is an excellent electrical insulator and, like other polyamides, is not affected by moisture. It has good impact resistance and chemical stability. PA12 has a number of improved varieties in terms of plasticizing and reinforcing properties.
Compared to PA6 and PA66, these materials have lower melting points and densities, and very high moisture retention. DuPont PA12 is not resistant to strong oxidizing acids.The viscosity of PA12 depends mainly on humidity, temperature and storage time. It has good flowability. Shrinkage is in the range of 0.5 %到2%depending on the material variety, wall thickness and other process conditions.PA12 Polyamide 12 or Nylon 12Typical Application Areas:Water meters and other commercial equipment, cable casings, mechanical cams, sliding mechanisms and bearings.

Chemical and Physical Properties
PA12 is a linear, semi-crystalline-crystalline thermoplastic material from butadiene. Its properties are similar to those of PA11, but the crystal structure is different. PA12 is an excellent electrical insulator and, like other polyamides, its insulating properties are not affected by moisture. It has good impact resistance and chemical stability, and there are a number of improved varieties of PA12 in terms of plasticizing and reinforcing properties. Compared to PA6 and PA66, these materials have a lower melting point and density, and a very high moisture retention rate.PA12 is not resistant to strong oxidizing acids.The viscosity of PA12 depends mainly on humidity, temperature and storage time. It has good flowability. Shrinkage is between 0.5%到2% The shrinkage rate is between 0.5 and 0.5, which depends mainly on the material type, wall thickness and other process conditions.

PA12 is also used as a nursing medical material. The mechanical properties of the catheter material are particularly important. The catheter must be easy to thread, but must not bend and never break. PA12 is an excellent material for catheter production because of its high burst pressure, good flexibility, chemical resistance, compatibility with body fluids, and non-toxicity. It meets the requirements of the US Food and Drug Administration and the European Union for medical products.
