Lanle expanded ptfe sheet has excellent properties such as creep resistance, cold flow resistance, ultra low temperature resistance, no pollution, easy installation and replacement. Under very small pretightening force, even under the changing pressure environment, it can withstand considerable internal pressure, which is very suitable for the sealing of flanges with rough or worn uneven and fragile enamel surface, The sealing occasions with temperature change meet the sealing requirements under harsh conditions and are used in various fields such as chemical industry, medicine and so on.
Application:
● Aerospace ● Petrochemical ● General Chemical ● Pulp and Pape
● Food and Beverage ● Power Generation
Advantages:
◆ Good chemical resistance ◆ Resistance to cold flow
◆ Excellent mechanical strength ◆ Reliable sealing
◆ Flexible & easy cutting ◆ Clean and non-toxic
