Product Details

This tape is manufactured from commercial grade polyimide film with a special silicone adhesive. The polyimide carrier is only 1 Mil, making this tape extremely conformable for irregular shapes and surfaces. Polyimide tape has the ability to maintain its excellent physical, mechanical and electrical properties over a wide temperature range. Used for high temperature masking found in conformal coating of PCBs, protection of gold fingers during circuit board soldering and electrical insulation of high temperature coils, motors and transformers.
