Ptfe Paste Extrusion Film

Ptfe paste extrusion film is used as primary insulation for high-temperature wires, cable jackets, and convoluted hose walls. These products are used in microwave and coaxial cable applications where low dielectric constant and high velocities are required. Cross-winding spools and flat spools are adapted to individual needs. We can offer widths from 4mm and very low thicknesses and densities.

Storing Recommendations for Unsintered Tapes

For maximum shelf life, it is recommended that PTFE films are stored in a clean, temperature-controlled environment at or below 21C with relative humidity below 50%.

 

FAQ:

 

Customer: How is your packing for ptfe film?

Foreverseal: The packing is flat pad and step pack/solid pad

 

Customer: How does PTFE FILM affect the fire resistance of cables?

Foreverseal: PTFE FILM has properties of and fireproof. When burning, the insulating material is not in direct contact with the flame but is melted by heat. At the same time, PTFE FILM will not affect the softness of the cable.

 

Customer: What’s the ptfe film width you can make?

Foreverseal: 4mm to 200mm
