Bertech High Temperature Polyimide Tapes are made of 1 mil polyimide film with 1.5 mil silicone adhesive for a total thickness of 2.5 mil. These tapes have been used in applications at temperatures as low as -269°C (-452°F) and as high as 260°C (500°F). Polyimide High Temperature Tapes are reliable and durable with a unique combination of electrical, thermal, chemical, and mechanical properties that withstand extreme temperatures, vibration, and other demanding environments. Polyimide Tapes are used in a range of industries including aerospace, automotive, consumer electronics, industrial, solar photovoltaic, and wind energy applications. They have a high dielectric strength. Silicon adhesive protection leaves no residue. They conform to MIL-P-46112, TYPE I. Available in amber color. These tapes are designed to be used for temporary masking purposes. RoHS Compliant.
