PA610 (Polyamide 610 or nylon 610) is an ivory-white to light yellow translucent solid made by the condensation polymerization of the neutralized salt of sebacic acid and hexanediamine. It has toughness, dimensional stability, wear resistance, oil and alkali resistance, low water absorption, and self-lubricating property. Processing methods of PA610 include extrusion, injection molding, and blow molding. End use applications include gears, bearings, cushions, sealants, insulators, electronic boards, thin films, filaments, etc.

PA612 (Polyamide 612 or nylon 612) is a milky white to light yellow translucent solid made by the condensation polymerization of the neutralized salt of dodecanedioic acid and hexanediamine. General properties are similar to those of PA610 except it has better flexibility and dimensional stability, and has lower water absorption. End use applications include monofilaments, cables and ropes, coil skeletons, mechanical components, tool frames, ammunition boxes, etc.
