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

Frequently Asked Questions

What rubber compounds are available in solid sheet?

SBR, EPDM, nitrile, neoprene and natural rubber compounds are available.

Can solid rubber sheet be cut to custom dimensions?

Yes — all solid rubber sheet is available cut to your exact size.

What is the difference between solid and sponge rubber sheet?

Solid rubber sheet is dense and non-compressible — used for anti-vibration, sealing and flooring. Sponge rubber is soft and compressible — used for cushioning and gasket applications.

What thicknesses are available?

Solid rubber sheet is available from 1.5mm up to 25mm in most compounds.

How is solid rubber sheet priced?

Priced per linear metre based on roll width. Contact us for bulk pricing.
