Keratherm - silicone free
Standard films
In case of concerns about using silicones, we offer you a ceramic-filled polyurethane film as an alternative
material. Besides good thermal and outstanding electrical properties, these films are characterized by very
good perforation strength. These good physical properties are matched with an excellent price-performance
ratio.
optional with adhesive coating
The following optional thicknesses are available: 0.125 mm; 0.250 mm; 0.3 mm; 0,4 mm; 0.5 mm;
