Polyimide Pressure Sensitive Adhesive Tape with Silicone Resin
This kind of tape is made of polyimide material
with heat-resistant silicone adhesive, which shows excellent
dielectric insulation properties, high heat resistant, excellent
solvent resistant, mask-off gold finger contacts during wave
soldering, short-term temp. 250c x 5sec, and is widely used for
electrical insulation on motor, transformer, coils, PCB making and
so on.
