White Color Pure Expanded PTFE Sheet Regular Size
1500~3000*1500*0.5-10mm
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.
