White Color Pure PTFE Joint Expanded Gasket Sealing Sheet Regular Size 1500 * 1500 * 0.5-10 mm
Introduction
The expanded polytetrafluoroethylene sheet material is made of 100% polytetrafluoroethylene, and this special manufacturing process makes its tensile strength almost equal in all directions. Lanle polytetrafluoroethylene expanded sheet is a product processed by more than 20 processes. The requirements for each process are very strict. In the past, foreign companies could produce and monopolize the Chinese market. The expanded polytetrafluoroethylene plate has good creep resistance, cold flow resistance, ultra-low temperature, no pollution, convenient installation and replacement, etc. Under the action of very small pre-tightening force, even in a variable pressure environment, it can also bear considerable internal pressure, and is very suitable for flange sealing with rough enamel surface or uneven wear and tear, which is fragile. The sealing occasions with temperature changes can meet the sealing requirements under harsh conditions, and can be used in various fields such as chemical industry, medicine, etc.
