High Temperature Masking Discs, also known as Polyimide Masking discs, are made of polyimide film. Polyimide masking discs have 1.5 mil of silicon adhesive which does not leave any residue. They can withstand temperatures of up to 500°F/(260°C). These masking discs have high dielectric strength and offers excellent performance in electrical and thermal insulation.

Applications:

• Masking of circuit boards during wave soldering or other electronic manufacturing processes
• Powder coating
• Automotive and transformer manufacturing
• Custom sizes are available upon request
