CMC 70105 is an adhesive tape based on a 50μm Kapton® HN polyimide film. The film is an excellent insulation film for the highest requirements and has a high breakdown voltage and good mechanical properties even at high temperatures. The polyimide film is one of the most powerful high-performance polymers on the market, chemically, physically and electrically. The film was equipped with a very cohesive, chemically stable, weather-resistant acrylate adhesive, which is also very suitable for long-term applications under maximum temperature loading (heat class H) up to a continuous temperature of 180 ° C. The material thickness and the very high breakdown voltage make this adhesive tape ideal for electrical insulation. Due to the thicker film (50μm instead of 25μm), the material has a higher breakdown voltage than the CMC 70100 product.
