Title:
フッ素ポリマーのバリア材料の製造方法
Document Type and Number:
Japanese Patent JP4782774
Kind Code:
B2
Abstract:
A novel densified fluoropolymer article is described which has a water vapor permeation of about 0.015 g-mm/m2/day or less, and preferably has a matrix tensile strength of at least 10,000 psi in two orthogonal directions. The articles are made by compressing expanded porous PTFE at pressures, temperatures and times which result in elimination of the pores, and subsequent stretching above the crystalline melt temperature.
