English name: polyhexamethylene dodecanamide resin；polyamide 612；nylon 612；PA612
PA612 Molecular formula:  NH(CH₂)₆CONH(CH₂)₁₀CO]_n
PA612 Uses/Features:
PA612 is a polymer material, fully named polyamide 612, also known as nylon 612. It is a semi crystalline engineering plastic with excellent physical properties and chemical stability. Compared to PA610, PA612 has a low density, extremely low water absorption, good transparency, high toughness and strength, excellent wear resistance, small molding shrinkage, good molding processability and dimensional stability, and excellent chemical resistance. Mainly used as a modified substrate, as well as as for covering bristles, monofilaments, and cables of high-end toothbrushes. It is also used for injection molding and extrusion production according to customer requirements, and can be widely used in industrial sectors such as aviation, electrical, shipbuilding, automotive, textile, and chemical machinery.
