Tomoegawa High Performance PTFE Sheets

Tomoegawa's High Performance Sheet F (HPS-F) is a porous thin sheet made of 100% polytetraflouroethylene, manufactured using Tomoegawa's unique wet laid process. HPS-F is characterized by excellent chemical and heat resistance, high electrical resistance, a non-adhesive nature, and uniform pore distribution. HPS-F can be processed into boards and tubes by laminating together sheets of varying pore diameters.
