   What is high molecular weight high density polyethylene (HMW HDPE)?

   • High molecular weight high density polyethylene (HMW HDPE) can be defined as a linear homopolymer or copolymer having an average molecular weight in the range of 0.2–1.0 million g/mol. To facilitate melt processing, such polymers are typically produced with a relatively broad or bimodal molecular weight distribution.

   Sep 1, 2020 · In this context, the term ‘ultra-high’ indicates a weight average relative molar mass, ˉM w, greater than 10 6. In practice, the minimum ˉM w for orthopaedic grades of polyethylene (PE) is about 5 × 10 6, which for linear PE means that chains have a contour length of at least 45 μm.
