STRETCHED POLYTETRAFLUOROETHYLENE FORMED ARTICLE, METHOD FOR PRODUCTION THEREOF, AND COMPOSITE ARTICLE

摘要

A stretched polytetrafluoroethylene formed article wherein at least a part of a formed article in a rod form comprising a stretched polytetrafluoroethylene porous material is coated or impregnated with a synthetic resin having a tensile modulus higher than that of polytetrafluoroethylene, and the part coated or impregnated with the synthetic resin is so deformed by twisting as to have a diameter less than that of the part not twisted; a method for producing the stretched polytetrafluoroethylene formed article; and a composite article using the stretched polytetrafluoroethylene formed article.
