Wet proofed Toray Paper 090 - TGP-H-090 - is a Teflon treated carbon fiber composite paper suitable for use as a catalyst backing layer. It has a total thickness of 280 um (microns). Toray Paper 090 is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials. Toray carbon paper 090 comes with a standard 5% wet proofing. The Teflon gives the carbon material a hydrophobic property to better function as an electrode backing material. All dimensions are nominal.
