شريط حشية PTFE الموسع
Expanded PTFE gaskets are special Teflon gasket tapes made from micro-porous and fibrillated مادة بولي تترافلورو إيثيلين. The Expanded PTFE joint sealant gasket tapes are both flexible and soft.
By expanding مادة PTFE البكر, you will get the perfect material for all your expanded PTFE tape gaskets. The EPTFE gasket tapes are thermal resistant and chemically inert with a relatively low friction coefficient.
Furthermore, the working temperature of expanded PTFE gasket tape varies from -400 and +550°F. When it comes to installing the expanded EPTFE gasket tapes, they can conform to uneven surfaces. Additionally, these tapes are suitable for low bolt torque applications.
Your Expanded PTFE Gasket Tape Specialists
Depending on the specific requirements, some expended PTFE gasket tapes have backing adhesive. The backing adhesive help to form tight sealing between components.
These easy-to-compress EPTFE gasket tapes come in different lengths and thicknesses.
Applications of EPTFE Gasket Tapes
