Description
White Silicone Sheeting — 1.5mm Thick
A premium-grade, food-approved white silicone sheet engineered for precision sealing, insulation, and fabrication across demanding environments. Available in standard A-series sheet sizes — A3, A4, A5, and A6 — this 1.5mm silicone rubber sheeting delivers outstanding flexibility, thermal stability, and longevity. Whether you are cutting custom gaskets, lining food-contact surfaces, or fabricating components for healthcare or industrial use, this material performs reliably from the coldest cold stores to the hottest processing lines.

Key Features
- Food-Approved Material: Meets FDA 21 CFR 177.2600 standards, making it safe for direct food and beverage contact.
- Wide Temperature Range: Performs continuously from −60°C to +230°C without degradation or loss of sealing integrity.
- Excellent Weathering Resistance: Highly resistant to ozone, UV light, oxidation, corona discharge, cosmic and ionising radiation, and general weathering.
- Flexible Yet Durable: 340% elongation to failure combined with a 60 Shore A hardness delivers a material that flexes without tearing.
- Easy to Fabricate: Can be cleanly cut to any shape using scissors or a craft knife — no specialist tooling required.
- Reliable Sealing Performance: Maintains effective seals at both high and low temperature extremes, ideal for gaskets and compression seals.
- Indoor and Outdoor Suitability: UV and ozone resistance make this sheeting equally effective in exposed outdoor environments.
- Non-Conductive: Suitable for electrical insulation applications in electronics and energy sectors.
