Fiberglass needled felt with PTFE membrane

Fiberglass needled felt with PTFE membrane is an excellent new type of high temperature resistant filtration material

Fiberglass needled felt with PTFE membrane is an excellent new type of high temperature resistant filtration material with reasonable structure, which uses 100%of fiberglass as raw material and is needle punched into felt. The felt has three dimensional micro porous structures with high void rate and less air resistance, which could eliminate up to 99.9% of the dust. Its filtration speed is 100% higher than the filtration material made by woven fabrics and suitable for use in the filters using the principal deducts.
