BIOSTABLE POLYETHER POLYURETHANE PRODUCT

摘要

A biostable polyether polyurethane article comprises a medical implant and/or a substratum for tissue and/or cell growth formed from an organic diisocyanate, a polyether polyol, a chain extender and a blowing agent. The density of the biostable polyether polyurethane article is less than 200 kg/m<3>. The ratios of the reaction components are selected to promote the formation of a three dimensional porous molecular structure of polyether polyurethane biomaterial.
