Specifics

TEFLON® FEP, PFA, TEFZEL®, and KAPTON® Film Fabrications (Heat-sealed)
200 gauge (.002") to 2,000 gauge (.020") is the most satisfactory range for heat-sealing. Gauges thinner than 200 tend to distort and will take on "wavy" appearance; gauges heavier than 2,000 are more difficult to seal. Type C and C-20 FEP film are not usually recommended for heat-sealing or vacuum-forming.

Lay Flat Tubing
We can fabricate heat-sealed "Lay Flat" tubing of TEFLON® FEP, PFA, TEFZEL®, and KAPTON® Films, and provide seamless, thinwall, FEP lay flat tubing in long lengths.

Size Limitations
Our Thermoforming capabilities allow us to fabricate both simple and complex configurations in various sizes.

Film fabrications have no length and width limitations, but these films are difficult to handle in large, bulky, configurations without creasing, attracting air-borne dust, etc. We will be pleased to discuss.
