A thermoplastic rubber composition for medical purposes

The rheology, vulcanization al, and the physico-mechanical properties of a composition of siloxane rubber and ultra-high molecular weight polyethylene are discussed. It is shown that such materials combine elasticity and strength. Inclusions of ultra-high molecular weight polyethylene in siloxane matrix, with large-sized globular structure, imparts material a good impact resistance property. Compositions developed may be used as polymer inserts for new generation of endo prosthetic appliances for hip joints
