Nylon PA11 is a fine bioplastic polyamide powder; The material is among the rare bio-based engineering plastics made out of renewable raw materials derived from vegetable oil, mainly castor oil.
Unlike PA11, Nylon PA12 is a synthetic whitish fine powder derived mainly from petroleum sources. It is optimized as much as PA11 for the use as a laser sintering material.
PA11 has properties quite similar to Nylon PA12. However, PA11 has a lower environmental impact, consumes less non-renewable resources to be produced, and has superior thermal resistance. Indeed, PA11 is stable to light, UV, and weather. It is also characterized by good elasticity, high elongation at break and high impact resistance.
Nylon PA12, on the other hand, is exceptionally strong even when temperatures dip below freezing. It is characterized by high strength, stiffness, strong resistance to cracking under stress, and an excellent long-term constant behavior.
