PTFE skived sheet

PTFE skived sheet production process,

First, PTFE resin molded into work-blank. Then skived to custom thickness to produce sheet/tape/film. It with the excellent chemical resistance, highly dielectric and long working life.

Common sheet can be processing to semi-density and high-density.Our technical can make sure the thickness min 0.015mm and max as customer request. In some specially application, we can filled some other materials to strengthen the physical strength/ electric conductivity/ slide coefficient,etc. And those strengthen to make our PTFE skived sheet to fitting more and more application.
