Polyimide Masking Discs, also known as Polyimide Discs, are primarily used in circuit board production, wave soldering and other applications. They are made from 1 mil thick polyimide film with 1.5 mil of silicone adhesive which does not leave any residue. Polyimide Masking Discs can withstand temperatures of up to 500°F/260°C. They are packaged in a 3" core.
- High temperature masking
- Insulation on Transformers, Motors and Coils
- Protection of circuit board during wave solder
- Solar Panels
