Chemfilm skived PTFE is produced by compression molding a cylindrical billet and "skiving" the film off of the billet in a lathe. Saint-Gobain has made extensive investments in the latest skiving technologies, enabling us to provide customers with high quality, competitively priced products. Skiving is carried out at three locations in the U.S., Germany and China. Skived film is produced in very clean areas with a major focus on contamination control. Our state-of-the-art skiving lathes make it possible to control to the tightest tolerances in the world.

Fluorowrap paste extruded PTFE is produced by blending fine-powder PTFE with a lubricant and pressing the film through an extrusion die. Multiple series of calendar rollers and dry cans set the dimensions of the film and drive off the lubricant. Paste extruded film is unsintered.

Applications include wire insulation and battery/fuel cell components; the most common use is in plumber's thread seal tape.

Saint-Gobain services the leading companies in these markets from our Hoosick Falls facility. Recent investments include automated equipment that enables us to achieve very tight tolerances. Our computerized slitting and winding equipment can slit to 3 mm, and wind flat pads, universal packages of nearly any configuration and StablEdge®. We produce films in many RoHS compliant colors.
