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

Technical Specifications

Ultra-Thin Silicone Film Sheet UK — Technical Specification

Property Value
Material 100% Silicone rubber
Thickness 20 micron (0.02mm)
Temperature Range -60°C to +230°C
Colour Translucent
Application Gaskets, seals, mould release, medical devices
Compliance FDA compliant grade available

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
