Webb1. Scope * 1.1 This test method is intended to measure shrinkage from mold cavity to molded dimensions of thermoplastics when molded by compression or injection processes with specified process conditions. 1.2 This test … WebbHigh Density Polyethylene (HDPE) is a cost-effective thermoplastic with a linear structure. It has no or low degree of branching. It is flexible, translucent/waxy, and weather resistant. The chemical structure of HDPE is: HDPE Molecular Structure HDPE is more rigid due to high crystallinity (> 90%).
