Ultra-high molecular weight polyethylene (UHMWPE) bearing surfaces in knee and hip prostheses are frequently manufactured by direct compression moulding of the as-polymerised powder. A study was made of the important role of the temperature–time sequ...

A problem in applications of ultra-high molecular weight polyethylene (UHMWPE) is the tendency for components to contain fusion defects, arising during processing of the as-polymerized powder. These defects have been implicated previously in failures... Read More about Processing of ultra-high molecular weight polyethylene : modelling the decay of fusion defects.
