Rapidly recoverable PTFE and process therefore

摘要

This invention relates to porous polytetrafluoroethylene (hereinafter PTFE) materials having the property of rapid recovery and a method for producing these materials. The microstructure of the porous PTFE material consists of nodes interconnected by fibrils, substantially all of the fibrils having a bent or wavy appearance. Artricles made from these materials are particularly suitable for use in the medical field, but are also useful in other areas such as filtration and fabric applications.
