Outer layer: PTFE (polytetrafluoroethylene) film; inner layer: EPDM rubber; high-temperature pressing and integral molding.
Outer layer: PTFE (polytetrafluoroethylene) film; inner layer: EPDM rubber; high-temperature pressing and integral molding.
Corrosion Resistance: PTFE isolates corrosive media, superior to ordinary rubber gaskets.
Excellent Sealing Performance: The rubber has sufficient elasticity, adaptable to flange irregularities and slight unevenness.
Non-stick to Flanges: Leaves no adhesive residue during disassembly and assembly; not easily stuck or torn.
Aging Resistance and Permeability Resistance; specially designed for leak prevention in acid and alkali chemical pipelines.
Chemical, electroplating, pharmaceutical, petroleum, wastewater treatment, corrosion-resistant equipment, acid and alkali valve flange sealing.
