Does Polypropylene Shrink When Heated. When it comes to polypropylene, determining shrinkage can be complicated by the material's high shrinkage characteristics. This value is referred to. In summary, some plastics seem to shrink when heat is applied, due to the negative thermal expansion (nte) phenomenon. Pvc, commonly used for pipes and cable insulation, can exhibit high shrinkage upon cooling. The shrinkage of molded plastic parts can be as much as 20% by volume when measured at the processing and ambient temperature. This page displays a chart that provides an. This volume contraction of polymers often. The chart below outlines typical mold shrink rates, as well as tonnage recommendations (per in²) and vent. But there are steps beyond tweaking the die that can mitigate these effects. Sometimes orientation is unbalanced, resulting in misshaped parts. The rate of shrinkage varies depending on the type of plastic and the conditions in which it is produced.
