Polyimide Discs, also known as Kapton® discs are made of high temperature polyimide film. These masking discs are used in masking of circuit boards during wave soldering or other electronic manufacturing processes. It can be used in powder coating, automotive and transformer manufacturing. Polyimide masking discs have high dielectric strength. Polyimide masking discs offers excellent performance in electrical and thermal insulation.
Polyimide masking discs have 1.5 mil of silicon adhesive which does not leave any residue. It can withstand temperature up to 500°F/260°C.
