PA66 plastic raw materials PA66 performance translucent or opaque white crystalline polymers, with plasticity. Density 1.15g / cm3. A melting point of 252 ℃. Brittle temperature -30 ℃. The thermal decomposition temperature greater than 350 ℃. Continuous heat 80-120 ℃, the equilibrium water absorption of 2.5%. To acid, alkali, most of the inorganic salt solution, alkyl halides, hydrocarbons, esters, ketones, such as corrosion, but soluble in phenol, formic acid and other polar solvents. With excellent wear resistance, self lubrication, high mechanical strength. However, water absorption, and thus dimensional stability is poor PA66 PA series, the highest mechanical strength, the most widely used species, because of its high crystallinity, so the rigidity and heat resistance are high. PA66 applications for high temperature electrical socket parts , electrical parts, gears, bearings, rollers, spring brackets, pulleys, bolts, impellers, fan blades, propellers, high pressure sealing gaskets, valve seats, pipelines, storage containers, rope, cable ties, belts, wheel adhesion agents, battery boxes, insulated electrical parts, wire core, spinning like.
