DICHTE POLYTETRAFLUORETHYLENE ARTICLES AND A PROCESS FOR PRODUCING THEM
摘要
This invention provides a densified previously expanded PTFE article having remnants of a fibril and node structure and a process for producing the article. A PTFE shape is compressed through the application of heat and pressure while the shape itself is under a vacuum, thus forming the densified ePTFE article. The densified PTFE article exhibits increased flexural strength. A diaphragm containing the densified ePTFE article as one layer is also disclosed.
