The polytetrafluoroethylene bubble point membrane prepared from ptfe as raw material is a membrane material with excellent performance for filtration and separation of fine particles.
It can be used for atmospheric dust removal, air purification, etc. The pore size of the membrane can be controlled to 0.2um, and the porosity can reach more than 88%. It is compounded with various filter materials such as needle felt, machine-made cloth, non-woven fabric, and glass fiber. The film-coated filter material with surface filtration performance makes the PTFE film-coated filter material have the characteristics of high peel strength, large air permeability, and uniform pore size distribution.
