PTFE film and tape

Polymer Company LLC specializes in supply of high-quality PTFE-4 film and tape.

 

PTFE-4 FILM

Main purpose of PTFE-4 film — insulation of electric wires. PTFE-4 films are strong and elastic, used for insulation of pipes, cables and various gaskets, and also submersible pumps used in aggressive media.

Method of production:

Film is made from pressurized cylindrical PTFE blanks by cold process. Wide film shaving cut from the blank, passes rolling reducing its thickness and forming same strength features along length and width of the product. Then ready confined film is rolled into rolls.

The obtained PTFE film, depending on the grade, is subjected to additional calibration and heated roll forming to orientate polymer molecules. Properties of PTFE films correspond to properties of the source materials.

PTFE-4 TAPE:

PTFE-4 tape gasket not oriented, grade PN (GOST 24222-80)

The tape is made by mechanical method from PTFE-4 blanks, pressurized with further thermal treatment from PTFE-4 powder grades P and PN (GOST 10007–80).

The tape is resistant to action of all media except gaseous fluorine, chlorine trifluoride, molten alkali metals. Tape working temperature range — from minus 269°С to plus 260°С.

Tape grade «PN» 0,5 and 0,7 mm thick is made with limit deviations ±0,07 mm at width 60 mm. According to agreement between the customer and manufacturer it is possible to produce tape with sizes not given in the table.

Tapes from PTFE compositions grades F4К15М5–L and F4К15М5–L–EA. TU 6-0505-138-80

  • Tapes grades F4К15М5–L and F4К15М5–L–EA are intended for production of antifriction parts: pads for guides of metal cutting machines, sliding supports, etc., used in machine tool building and other machine-building industries.
  • Tape grade F4К15М5–L is obtained by stripping cylindrical blank from compositions F4К15М5 per TU 6–05–1413–76.
  • Tape grade F4К15М5–L–EA is obtained by processing tape grade F4К15М5-L by glow discharge at both sides.
  • Tape grade F4К15М5–L–EA may be attached to metallic bases by various glues (for example, glues based on epoxy resin К–153А or B, etc.).

Warranty storage period for tape F4К15М5–L — 3 years since day of production.

Warranty storage period for tape F4К15М5–L–EA — 1 year since day of production (treatment with glow discharge).
