Plastic Fluropolymer PFA Film

PFA film exhibits many of the performance characteristics of PTFE in a clear, transparent form but can be heat sealed & thermoformed, metalized or laminated to a wide variety of materials. PFA film has a combination of excellent dielectric properties across a wide temperature and frequency range, the highest level of chemical & stress crack resistance together with excellent clarity and good weatherability.

PFA Film Applications:

Forbest offers one universal grade of PFA film to service applications that require high flex life and stress crack resistance such as thin film diaphragms for all kinds of chemical pumps and thermoformed flat products designed for extremely harsh environments.

The combination of chemical resistance and high temperature performance over a wide frequency range make PFA film an ideal component in circuit board fabrication and flat cable insulation applications. The high temperature performance and non-wetting surface of PFA film also make it an ideal material for use as a high temperature release film for composite manufacturers.

Usage:

·    F4 varnished belt, conveyor belt, tent head bonding

F4 plate fusion welding film

Dielectric

Making high temperature adhesive tape substrate

Anticorrosive lining

Utilization characteristics:

Excellent adhesion and heat sealability with F4

Below the melting point, do not allow any object to wet, above the melting point and F4, metals have good adhesion. And self-adhesive (sealing)
