what is PA12 or nylon12 in 3D printing

       

PA12 is also called nylon 12. The basic raw
material of polymerization is butadiene, which can rely on petrochemical
industry. The material is thermoplastic semi crystalline. Its properties are
similar to PA11, but its crystal structure is different. PA12 is a good
electrical insulator and, like other polyamides, will not be affected by
humidity. It has good impact resistance and chemical stability.

The viscosity of PA12 mainly depends on
humidity, temperature and storage time. It's very liquid. The shrinkage is
between 0.5% and 2%, which mainly depends on the material variety, wall
thickness and other process conditions. PA12 polyamide 12 or nylon 12 typical
applications: water meter and other commercial equipment, cable sleeve,
mechanical cam, sliding mechanism, photovoltaic backplane and bearing, etc.
