Pure PTFE Envelop Gasket
PTFE Envelope Gasket with core material of flexible materials ( consists of asbestos,non-asbestos,rubber,corrugated stainless steel etc ),
which is wrapped by PTFE. It is the ideal solution for applications demanding virtually 100% chemical resistance and where the mechanical
properties of a compressed gasket material are needed. It suits for tower, groove and all kinds of equipments of strong acid,halogen corrosive liquids and anti-contaminated food flanges. It is widely used in the chemical, petrochemical, pharmaceutical and food industries.
Temperature range from- 200~+250oC depending on the core.
Mechanical strength dependent on core selection.
Pressure≤50bar
Compressibility: ≥ 20%
Recovery: ≥ 30%
Stress release: ≤45%
Leakage rate: ≤1x10-3 cm3/s.
