High Temp Polyimide Discs - ULD012

High Temp Polyimide Discs – 14mm x 2500 Roll Length | Vital Parts – ULD012

Our Ultra High Temperature Polyimide Discs, or Kapton Discs as they are also known, are perfect for the highest temperature situations, being able to withstand upwards of 260°C. This exceptional thermal resistance makes them ideal for demanding applications such as powder coating, anodising, shot blasting and use within electrical systems and circuitry.

We also offer a range of High Temp Polyester Discs

What are High Temp Polyimide Discs?

High Temp Polyimide Discs are die-cut masking solutions manufactured from polyimide film. Known for their thermal stability and dielectric strength, these discs maintain physical and electrical properties at extreme temperatures. Unlike standard masking tapes, discs offer quick, accurate coverage for small holes and contact points. Their amber colour provides clear visibility during application, while the silicone adhesive ensures clean, residue-free removal.

Key Features:

• Ultra high temperature resistance up to 260°C
• Stable physical properties under thermal stress
• Perfect for fine masking in powder coating and anodising
• Can be supplied in custom shapes and sizes
• Amber polyimide film with silicone adhesive backing
• Clean removal with no residue left behind
• Excellent electrical insulation and thermal conductivity

Key Applications and Industries

In the UK market, High Temp Polyimide Discs are widely used in industries requiring ultra high-temperature resistance and precision masking. Common applications include protecting threads and contact surfaces during powder coating, safeguarding circuits and components in electronic manufacturing and masking restricted zones during shot blasting or surface treatment. They are especially valued in the aerospace, automotive and electrical engineering sectors for their reliability in harsh conditions.
