PB12000 SERIES

Porous PTFE

Porous PolyTetraFluoroEthylene (pPTFE) is a very low-density PTFE material. It combines the uniqueness of PTFE properties with a porous structure. The degree of porosity and porous size can be adjusted as a function of your application needs.

Porous PTFE materials are usually used as venting and filter elements, but their jagged surface also makes PB12000 materials excellent optical diffusers.
