Kapton® film (Dupont)

Polymide (Kapton® Dupont) is film developed by Dupont which remains stable in a wide temperature range, from -269° C to +400° C. It is used in flexible printed circuits and in the outer layer of the astronauts’ space suits, designed to provide thermal protection and protection against micro-meteorites.

FEP film

FEP is a tetrafluoroethylene and hexafluoropropylene copolymer. It differs from PTFE (polytetrafluoroethylene) because of its hot workability using conventional injection moulding and extrusion techniques. FEP shares the characteristics of PTFE with low friction and low chemical reactivity, but it is more workable. FEP is softer than PTFE and melts at 260°C. It is highly transparent and resistant to UV rays.

We manufacture:

  • Reels to the height required by the customer
  • Parts to drawing
  • Transparent protective walls

Polyolefin (UHMW polyolefin film) is an organic compound produced following the polymerisation of unsaturated aliphatic hydrocarbons or olefins, such as polyethylene.

Mylar® (Dupont)

Terephthalic acid and ethylene glycol polymer, in the form of translucent film. Polyethylene terephthalate or polyethylene terephthalate (trade names: Arnite, Tecapet, Impet and Rynite, Ertalyte, Hostaphan, Melinex and Mylar films, and Dacron, Diolen, Tergal, Terital, Terylene and Trevira fibres), part of the polyester family, is a thermoplastic resin composed of phthalates suitable for contact with food.

Depending on the production processes and the thermal history, it can exist in amorphous (transparent) or semi-crystalline (opaque white) form. It is also used for its electrical properties, chemical resistance, high temperature performance, self-extinguishing capacity and moulding speed. It is often indicated by the abbreviations PET, PETE, PETP or PET-P. PET decomposes at a temperature of 340° C, with the formation of acetaldehyde and other compounds.

Our polyethylene terephthalate film is supplied in variable thicknesses (standard thickness 0.25 mm) and heights up to 2,500 mm.
