We recommend examining any material prior to use to confirm suitability for your specific application. Typical Applications Gasket cutting and sealing Vibration damping and isolation Protective padding and cushioning Weatherproofing and draught exclusion Anti-slip surface lining Craft and hobby projects Noise and sound attenuation Machinery and equipment protection Packaging and transit protection Temporary flooring and matting Usage Notes Ensure the application surface is clean, dry, and free from oil or grease before bonding. Not recommended for prolonged exposure to petrol, solvents, ozone, or open flame environments. Due to the nature of this product, minor tolerances in size and thickness are inherent and within the stated specification. Frequently Asked Questions What sizes are available? Sheets are supplied in A4 (210 x 297mm), A3 (297 x 420mm), and A2 (420 x 594mm). Larger sizes are available on request. How does the self-adhesive backing work? Each sheet has a factory-applied pressure-sensitive adhesive protected by a release liner. Peel the liner, position the sheet, and press firmly onto a clean, dry surface. Can the sheet be cut to a custom shape? Yes. The material cuts cleanly with scissors or a craft knife, making it straightforward to produce gaskets, pads, or strips to your exact dimensions. What is the hardness and what does it mean in practice? The hardness is 65 Shore A — a medium-firm rubber that resists compression while retaining enough flexibility to conform to uneven surfaces and absorb impact. Is this sheet suitable for outdoor use? It performs reliably across −30°C to +70°C and is waterproof, making it suitable for many outdoor applications. However, it is not recommended for environments with prolonged ozone, petrol, or solvent exposure. What is the thickness tolerance? Thickness is 3mm with a tolerance of ± 0.3mm. Sheet dimensions carry a ± 2% tolerance, which is standard for this type of rubber material.
