Polyester films / Polyester adhesive tapes
PET films and PET adhesive tape
Polyester films (PET, polyethylene terephthalate) are regarded worldwide as high-quality engineering films. They combine many positive properties with a favorable price, which is why they are used in a wide range of industries. Polyester films are chemical-, age- and tear-resistant plastic films that can be used in the temperature range between -70 to +150°C. Examples of such applications are voltage-resistant electrical insulation, mechanical or chemical barriers, highly transparent protective films or in the packaging industry as aroma and transport protection.
PET films....
- offer a very high dielectric strength up to 280kV/mm
- are available in a wide variety of designs
- are chemically very stable
- can be highly transparent (screen films)
- can be printed and are very gas- or aroma-tight
- have excellent dimensional stability even at elevated temperatures
- can be thermoformed or colored
- can be die-cutted and coated
CMC Klebetechnik mainly stocks Hostaphan® polyester films from Mistubishi and Mylar® polyester films from DuPont. However, Lumirror™ from Toray, for example, can also be offered.
In addition to the cutting of precisely fitting rolls, further processing into die-cut parts and laminates is possible. Customized coatings of the universal polyester films are also possible on two large coating lines.

Mylar®
Mylar® is DuPont's trade name for a family of polyester films that become milky opaque with increasing thickness. It offers an excellent combination of electrical as well as chemical, thermal and physical properties. PET films are also inexpensive due to the large volume of film produced.
The polyester film is characterized by excellent resistance to common solvents. Mylar® films can be used at temperatures from -70 °C to 150 °C. Since they do not contain any plasticizers, they do not become brittle when aging under normal conditions. Some grades are particularly UV-resistant and others are now extremely resistant to hydrolysis. Mylar® polyester film can be used permanently up to 130°C (class B according to UL 746C) as insulation in transformers, electric motors and other electrical and electronic equipment. The UL file number is E93687 Mylar® films are available in a wide range of thicknesses. For example, there are 4µm versions used in capacitor manufacturing. In the range between 19µm and 350µm they are stocked as standard by CMC Klebetechnik.

Hostaphan® films are available in many specific designs.
Hostaphan® films can be used in the temperature range from -70 °C to 150 °C. Since they do not contain any plasticizers, they do not become brittle or fragile when aging under normal conditions.
