PPA plastic PPA is made by polycondensation of aliphatic diamine or diamine with benzene ring-containing diamine or diamine. Compared to aliphatic polyamides, the introduction of a rigid benzene ring in the molecular chain results in a significant increase in mechanical strength and heat resistance, as well as a significant decrease in water absorption. Compared with aromatic polyamides, semi-aromatic polyamides have more flexible aliphatic structures in the molecular weight and lower melting points, which effectively improves the processing performance of aromatic polyamides. Because PPA has both the excellent performance of aromatic polyamide and aliphatic polyamide good molding processability, after years of development has become one of the most important varieties of special engineering plastics, is widely used in electronic and electrical appliances, automotive industry and other fields. PPA filling Long glass fiber compounds Glass fiber reinforced PPA composites are considered to be the best resin for replacing steel with plastic because of their high temperature resistance, high strength and low density. Long glass fiber reinforced PPA composites have better physical and mechanical properties than conventional short-cut fiber reinforced pellets.
