Silicone Polyimide Tape
Polyimide film tape with silicone adhesive for high-temperature masking and electrical insulation. Standard grades are rated up to 260°C; specified HT silicone grades are rated up to 300°C.
Technical overview
Silicone polyimide tape
CGS silicone polyimide tapes combine a polyimide film backing with a pressure-sensitive silicone adhesive. Select the standard or HT adhesive grade according to the process temperature, exposure time, substrate, and removal requirements.
