According to the plasticizer content, PVC plastic is often divided into: rigid PVC, plasticizer content less than 10%; semi-rigid PVC, plasticizer content of 10-30%; soft PVC, plasticizer content 30-70%
Type of PVC wire bundles
According to the plasticizer content, PVC plastic is often divided into: rigid PVC, plasticizer content less than 10%; semi-rigid PVC, plasticizer content of 10-30%; soft PVC, plasticizer content 30-70%.
Industrial PVC has no obvious melting point, starts to soften at about 80 °C, heat distortion temperature (at 1.82 MPa load) is 70-71 ° C, starts to flow at 150 ° C under pressure, and begins to slowly release hydrogen chloride, resulting in polymerization Vinyl chloride discoloration (from yellow to red, brown, and even black).
