Product Details

Ultra-Thin Silicone Film Sheet UK | 20 Micron Translucent Gasket and Sealing Material

Our 20-micron (20μm) silicone film sheet is the thinnest silicone available in our UK range — engineered for precision sealing, gasketing, and insulation where conventional sheet thicknesses would compromise performance or fit. Fully translucent, food-grade and temperature-resistant.

Why Choose 20 Micron Silicone Film?

Ultra-Thin Profile (20μm) – negligible added thickness for tight-tolerance assemblies
Translucent Appearance – visually unobtrusive in sensitive applications
Food-Grade Compliant – safe for contact with food processing equipment
Excellent Temperature Range – performs from -60°C to +200°C
Chemical Inertness – resists oils, solvents, acids and alkalis
Flexible & Conformable – wraps easily around curved or irregular surfaces
Dielectric Properties – suitable for electrical insulation applications

Typical Applications

Precision gasketing in medical and laboratory equipment
Food-grade sealing in processing machinery
Thin-film electrical insulation and circuit protection
Release liner in composite manufacturing
Microfluidics and diagnostic device sealing
Aerospace and automotive precision assemblies

Why Choose Ultra-Thin Silicone Film?

When standard silicone sheet is too thick for precision sealing applications, ultra-thin silicone film delivers consistent performance at just 20 microns. Key benefits:

Extreme precision sealing — ideal for tight-tolerance flanges and instrument housings
Excellent temperature resistance — stable from -60°C to +230°C
Chemical inertness — resistant to most acids, alkalis and solvents
Low outgassing — suitable for vacuum and cleanroom environments
FDA compliant — food-safe and medical device applications

Common Applications

Precision instrument and electronics sealing
Medical device manufacturing gaskets
Pharmaceutical packaging lines
Mould release and parting film in composite manufacturing
