Toray Paper 120 - TGP-H-120 - is a carbon fiber composite paper suitable for use as a catalyst backing layer. It has a total thickness of 370 um (microns). Toray Paper 120 is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.

Toray carbon paper 120 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.

Quantity discounts, custom sizes, and custom wet proofing available upon request.

A great subsitute for Toray Carbon Paper 120 is AvCarb MGL370. The MGL370 has similar specifications to Toray 120 and is much cheaper per sheet.

Lead time may be four to five business days.
