Soft Expanded PTFE Sheet ePTFE For Gasket Sealing
Expanded PTFE Gasket is made of 100% PTFE of puffed PTFE material cut or punched. Expanded PTFE material (eptfe) expands PTFE into a unique material with strong, tough and porous properties and is highly fibrotic.
It not only maintains the unique properties of PTFE itself - excellent chemical stability (not affected by general chemicals); extremely low coefficient of friction; wider operating temperature; non-aging and permanent durability.
Application
Chemical, petrochemical, oil refining, chlor-alkali, acid making,
phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting,
iron and steel, atomic energy and high-purity products production (such as ion membrane electrolysis),
viscous material transportation and operation, highly strict hygiene requirements of food, beverage and other processing and production
