Polyester Discs - HID012

High Temp Polyester Discs – 14mm Disc Diameter & 2500 Discs per roll | Vital Parts – HID012

Our High Temp Polyester Discs are a durable and versatile masking solution designed to withstand extreme heat during powder coating, e-coating, anodising, and industrial painting. These discs offer a clean, precise finish by masking off round or irregular areas without wrinkling or lifting under thermal stress. Commonly known as die-cut polyester discs, they are crafted from high-performance green polyester film and backed with a silicone adhesive for clean removal post-curing.

What are High Temp Polyester Discs?

High Temp Polyester Discs are circular die-cut shapes made from the same high-grade polyester film used in industrial masking tapes. Designed for use in high-temperature finishing environments, these discs provide excellent resistance to temperatures up to 220°C. They feature a low tack silicone adhesive that ensures a residue-free release, even after extended exposure to heat during baking or curing. Their robust construction makes them suitable for precise masking of bolts, threads, contact points, or complex features on metal and plastic components.

We also offer a range of High Temp Polyimide Discs

• Custom shapes and sizes available on request

Key Applications and Industries

In the UK market, High Temp Polyester Discs are used widely in finishing and manufacturing operations where heat-resistant masking is critical. These discs are commonly applied in powder coating plants for masking off threads and holes prior to baking. Electronics and electrical manufacturers rely on them for insulating contact points during soldering or wave processes. Automotive and aerospace sectors use them during multi-stage finishing where masking accuracy and residue-free removal are essential. Their fast, uniform application also benefits high-volume production lines requiring consistent masking performance.
