The chemical name of PA6 is polycaprolactam. PA6 is a translucent or opaque milk self-colored crystalline polymer particle, with a melting point of 220°C, a thermal decomposition temperature greater than 310°C, a relative density of 1.14, and a water absorption rate (24h in 23°C water) of 1.8%. It has excellent self-lubricating properties and mechanical properties. High strength, good heat resistance, good electrical insulation performance, excellent low temperature performance, self-extinguishing, good chemical resistance, especially excellent oil resistance. Processing and molding is easier than PA66, the surface gloss of the product is good, and the service temperature range is wide. However, the water absorption rate is high and the dimensional stability is poor. Compared with PA66, it has less rigidity, lower melting point, can be used for a long time in harsh environments, and can still maintain sufficient stress in a wide temperature range. The continuous use temperature is 105°C, the dielectric loss is 0.03MHz, and the breakdown voltage is 16kV/mm , Flame retardant grade V-2, cold temperature -30 ℃.
the
PA6 is one of the varieties with large output, large consumption and wide application in the nylon series. Widely used in automobiles, electronics, electrical appliances, machinery, transportation, textiles, chemicals, paper, packaging and other industries.
Mechanical industry: PA6 components used in mechanical products mainly include transmission gear bushings, sealing gaskets, bearing frames, rollers of moving machinery, rolling steel slide plates and matching power supply device components. Antistatic reinforced PA6 is used as a textile shuttle, its service life is several times that of wood, and it saves a lot of wood for the region.
