Poly-Smith PTFE 15 GL-LF Features & Benefits

Product Highlights

Glass filler is often used to reduce creep in the final product. It improves wear resitance, and is chemically inert to water and solvents. It has the least effect on electrical properties, while slightly increasing the porosity.

Applications & Uses

General Applications

Recommended for valve seats, gaskets, seals and components requiring resistance to creep and chemical attack. Suitable as a bearing material for low PV values. At high loads and speeds the wear increases and there is a risk of scoring shafts.
