Application

The chemical and physical properties of PA6 are similar to those of PA66. However, its melting point is low and the process temperature range is wide. Its impact resistance and solubility are better than PA66, but its moisture absorption is also stronger. Because many quality characteristics of plastic parts are affected by moisture absorption, this should be fully considered when using PA6 to design products. In order to improve the mechanical properties of PA6, various modifiers are often added. Glass fiber is the most common additive. Sometimes synthetic rubber, such as EPDM and SBR, is added to improve impact resistance. For products without additives, the shrinkage of PA6 is between 1% and 1.5%. Adding glass fiber additives can reduce the shrinkage to 0.3% (but it is slightly higher in the direction perpendicular to the process). The shrinkage of molding assembly is mainly affected by the crystallinity and moisture absorption of the material. The actual shrinkage is also a function of the plastic part design, wall thickness and other process parameters.

PA6 nylon is widely used in the industrial production of bearings, round gears, cams, bevel gears, various rollers, pulleys, pump impellers, fan blades, worm gears, thrusters, screws, nuts, gaskets, high-pressure sealing rings, oil resistant sealing gaskets, oil resistant containers, shells, hoses, cable sheaths, shears, pulley sleeves, shaper sliders, electromagnetic distribution valve seats, cold aging equipment, gaskets, bearing cages Various oil pipelines, pistons, ropes, transmission belts, zero fog materials for textile machinery and industrial equipment, daily necessities and packaging films on automobiles and tractors.
