VET-090, also known as VET-H-090, is a high-quality carbon fiber composite paper designed as a catalyst backing layer. With a thinness of only 280 microns (µm), it provides a lightweight and cost-effective alternative to traditional woven carbon cloth Gas Diffusion Layer (GDL) materials.
One of its standout features is the minimum 5% weight wet proofing treatment, which imparts hydrophobic properties to the paper. This treatment, incorporating Teflon, enhances its water repellency and makes it an excellent choice as an electrode backing material. The hydrophobic nature of Toray Paper 090 prevents water flooding and ensures optimal performance of the catalyst.
In summary,VET-090 offers a refined solution for catalyst backing applications. Its thin and lightweight composition, coupled with the hydrophobic properties from the wet proofing treatment, makes it a cost-effective and efficient choice as an electrode backing material.
