Product description

Description

PTFE  Teflon Film has made extensive investments in the latest skiving technologies, enabling us to provide customers with high quality, competitively priced products. For its excellent dielectric capability, anti-aging and anti-corrosion property, super thin PTFE teflon skived Tape and Film has been used in a wide range of industries including the electronics and semi density industries.

PTFE is an amazing non-stick material, but what about when you need to glue it to the surface of another material, In order to bond standard PTFE to another surface such as stainless steel, a process called "etching" is required. Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium ammonia etching is usually the most economical answer. This process uses of a mixture of sodium and ammonia that is formulated to create a bondable surface both quickly and efficiently. 

From microchips to full size rolls, any shape or complexity, including tape, sheet, tubing, molded shapes & machined parts of any configuration can be etched & bonded. This treatment can be accomplished on one or more surfaces, or selectively within close tolerances.

Feature

1. Temperature resistance ---It is able to work stably between -180°C to +260°C.

2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.

3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.

4. Anti-aging, weathering resistance.

5. Excellent insulation property.
