Three grades of polyethylene, with weight-average relative molar masses, ¯¯¯ ¯M W M ‾ W, of approximately 0.6 × 10 6, 5 × 10 6, and 9 × 10 6, were supplied as compression mouldings by a leading manufacturer of ultra-high molecular weight polyethylene (UHMWPE). They were code-named PE06, PE5, and PE9, respectively.
Ultra-high molecular weight polyethylene (UHMWPE) fibers are the strongest and lightest fibers available, due to their combination of high strength and low density. The basis for the development of high-strength UHMWPE fibers was laid down in the 1960s by the discovery in the DSM research laboratory of a new fibrillar crystal form for UHMWPE ...
