Toray Carbon Paper TGP-H-060 (Hydrophilic, No MPL)
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 is untreated (no PTFE / no wet proofing) and therefore exhibits the inherently hydrophilic nature of the carbon fiber substrate. This allows good wettability and makes it suitable for applications requiring liquid absorption or catalyst coating.
