3M PTFE Tape

3M PTFE Film Tapes (Electrical) 3M™ PTFE Film Electrical Tapes are high-temperature tapes used in applications requiring consistent performance and minimum shrinkage across a wide range of temperatures

3M PTFE Film Tape (Industrial)

5490, 5491, 5480, 5481;

Gray PTFE slick-surface extruded film with pressure-sensitive silicone adhesive and smooth, lay-flat backing

Benefits include:

• Wrap web rollers with a slippery, low-energy surface for smoother material movement
• High heat reflectivity to protect temperature-sensitive materials against heat damage and hot spots
• Cover web-former edges to minimize friction during folding
• Anti-stick for ready release and clean-up of hot plastic; prevent plastic film from sticking to heat bar
• Protect surfaces against heat, chemicals, and friction

Characteristics:

• Low coefficient of friction for a slippery, self-lubricating surface
• High temperature resistance
• Anti-stick, ready release facilitates clean-up of hot plastic and prevents build-up
• Chemical barrier for harsh conditions
• Conforms to rollers for easy application and effective service

Key customer needs:

• Sealing, shielding and noise reduction
