Toray Carbon Paper without MPL – TGP-H-060 (Hydrophilic)
Product Name & Description
Toray Paper TGP-H-060 is a carbon fiber composite paper suitable for use as a catalyst backing layer. It has a total thickness of 190 um (microns). Toray Paper TGP-H-060 is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.
Toray carbon paper TGP-H-060 comes with a minimum of 5% weight wet proofing. The Teflon gives the carbon material a hydrophobic property to better function as an electrode backing material.
