PTFE and ETFE Adhesive Tapes

Polytetraflourethylene (PTFE) is characterised by its extremely high chemical resistance. High thermal resistance and very good dielectric strength (even with corona discharge) complete the advantages of this product family. Teflon adhesive tape is also a familiar name in the industrial field.

The films are used e.g. in mould making as a separating film because of their very smooth and repellent surface, which has a non-stick effect. They can also be used as a film to reduce frictional resistance between sliding surfaces or as high-quality electrical insulation.

Ethylentetrafluorethylene (ETFE) - Films for the architecture sector. Opt for the highest quality. The ageing-resistant ETFE film and weatherproof, transparent adhesive reduce maintenance costs to a minimum and will therefore increase customers’ confidence in you over the long term. The durable ETFE adhesive tape is more cost-effective than most alternative solutions. This means that you will win more contracts and your applications will be more successful. And the width you or your customers require is always available.

Adhesive repair tape for film greenhouses: Adhesive tapes made of ETFE film are ideal for repairing greenhouses made of high-quality films. The adhesive tapes in the product range CMC 777xx adhere to almost any sub-surfaces permanently and are resistant to weathering. Even moisture and light dirt do not prevent an effective repair (although cleaning is always recommended as a matter of principle).

CMC 75100
​PTFE-Adhesive Tape 
Colour: grey 
Liner: Silicone Paper

Adhesive: on one side Acrylate

Substrate Thickness: 0,100 mm
Total Thickness: 0,130 mm
Chemical-resistant PTFE tape for sealing and as an anti-stick surface against various adhesive materials, very good corrosion resistance (insulation).
The film was equipped on one side with a very cohesive, chemically very stable, weather-resistant acrylic adhesive, which is also very suitable for long-term applications under maximum thermal load (Thermal class H).
PTFE films have an extremely low sliding resistance. The chemically extremely resistant polytetrafluoroethylene film is also used as a seal for containers in the chemical industry or as wall linings in paint shops. In mold making, the PTFE film facilitates the molding of e.g. GRP, CFK or concrete components. The acrylic adhesive facilitates the fixation and provides a reliable hold.

Main advantages of using ETFE films

  • Self-cleaning surface (no complex cleaning equipment)

  • Highly transparent >92 %, including UV light (positive for plants and people)

  • Light weight, therefore sub-structure does not have to be as complex as for glass

  • Good heat insulation when using ETFE cushions as a result of the air cushion between the layers of film

  • Good acoustic properties, as the soft film does not form any hard reflective surfaces and therefore no disruptive echoes are created in the space

  • Non-flammable film that melts in the event of a fire without spreading the fire

  • Mechanically very practical material with good elasticity and resistance to ripping and tearing

  • Can be thermoformed and thermo-welded

  • Extremely strong resistance to UV, weathering, chemicals and both high and low temperatures

  • Unlike glass, ETFE films follow subsequent deformation of the structure

  • Low smoke generation, low toxicity in the event of a fire

  • Better mechanical strength (pressure, tensile) than PTFE

  • Adhesion with CMC 77700, CMC 77701 and CMC 77703 adhesive tapes also stable under water (adhesion in dry state)

  • Self-adhesive ETFE films are excellent protective surfaces that are easy to clean and offer high chemical resistance

  • ETFE adhesive tapes from CMC Klebetechnik are an excellent choice for adhering ETFE films. Good adhesion force, no risk of sub-surface migration and high transparency are guaranteed.
