Self-Adhesive EPDM Foam Sheets | Sponge Rubber Gasket Sheet | Flashback® Tape

Product Description

Flashback® EPDM Foam Sheet lets you cut your own gaskets, seals and pads to exactly the shape you need. It is the same closed cell EPDM sponge rubber as our EPDM foam tape, supplied as a 500mm wide sheet so you can cut shapes that a tape width cannot cover.

Closed cell EPDM sponge rubber compresses to fill gaps and uneven surfaces, then holds its shape. It has excellent resistance to ozone and weathering, so it suits both indoor and outdoor use.

For outdoor and weather-exposed seals, EPDM is often a better choice than neoprene sponge sheet. Neoprene is usually preferred where oils or fuels are present, as EPDM is not suitable for contact with them.

The self-adhesive backing means you can cut, peel and stick. It cuts cleanly with scissors or a sharp knife. For a good bond, stick it to a clean, dry, smooth surface.

Manufactured in the UK.

Which Thickness?

• 1.5mm: for thin, close-fitting gaskets and seals, lining and padding where space is tight
• 3mm: for slightly larger or less even gaps, where you need more compression
• 6mm: for larger or uneven gaps, and where you need more cushioning

As a rule, choose a thickness slightly larger than the gap so the sponge rubber compresses when fitted. Need something thicker? Our EPDM foam tape comes in thicknesses up to 15mm, and our thickness calculator will help you choose.

Sizes

• 500 × 500mm sheet: for small gaskets and one-off jobs

Important

EPDM foam sheet is a compression seal for use behind a trim, frame, panel or lid. It is not a cover tape, roofing membrane or waterproof covering.
