KERATHERM^®green

This silicone elastomer film is characterized by its excellent electrical values. It exhibits good thermal behavior. Optional fibre glass reinforcement leads to very goodmechanicalproperties.Thesefilm types possess excellent mechanical stability along with good perforation strength. Due to its structure, Keratherm green is extremely self-adhesive.

Additional adhesive coatings available.

• - automotive
• - telecommunication units
• - high voltage units
• - DC-DC converters
