Our PTFE sheet is made of 100% PTFE through a special process. It has high tensile strength, low creep, high and low temperature resistance, corrosion resistance, no asbestos, no additives, non-toxic, aging resistance. It also comply with RoHS requirements. It's airtight, watertight and better performance of anti leakage. Under severe corrosive environment and high temperature, it can still maintain excellent sealing. When tank lining in the chemical processing and semiconductor industries, where the prevention of leakage and contamination is vital to material purity and integrity.
