Self Adhesive Sponge Strip (Expanded Neoprene)
Our self adhesive sponge strip is available in a range of widths and thicknesses. This sticky backed closed cell sponge rubber does not absorb water and is suitable for making a watertight seal on boat hatches, lockers, car boots, enclosures, and cabinets. Also known as sponge tape, this product can be easily stuck to most clean flat surfaces by peeling off the backing paper and sticking in place.
Manufactured from expanded neoprene, self adhesive sponge strip is a soft, flexible and waterproof material that has an excellent resistance to UV, air and ozone. It has an operating temperature range between -40°C to +100°C. We recommend that you compress our expanded neoprene by approximately 30% to minimise the chance of damaging the seal with excessive and prolonged compression. For example, we recommend using 6mm thick sponge tape to seal a 4mm gap.
The self adhesive backing is suitable for applications with limited water exposure, such as falling water droplets and light splashes. It is not recommended for use in environments that will cause the sponge strip to experience constant water immersion. Where a large amount of moisture or water is present, we recommend that you use plain expanded neoprene and a good contact adhesive, such as our A262.
