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.
L'invention concerne un article densifié en PTFE préalablement expansé, présentant des restes d'une structure fibrillaire et nodale, ainsi qu'un procédé pour fabriquer cet article. Une ébauche en PTFE est comprimée par l'application de chaleur et de pression tandis que l'ébauche elle-même est soumise à un vide, formant ainsi l'article densifié en PTFE expansé. Cet article présente une résistance à la flexion accrue. Une membrane renfermant ledit article sous forme d'une couche est également décrite.
