Expanded PTFE Sheet

Description

Expanded PTFE sheet manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions.Widely used for sealing flange joints in pipelines as well as hydraulic and pneumatic systems. Pure, multidirectionally expanded PTFE, asbestos free, chemically resistant to fluids from 0 to 14 in the pH range. It is a food-safe product with great chemical resistance, making it a preferred sealing material in the food, beverage, and pharmaceutical sectors.
