This Plain Expanded Neoprene Sheet is 25mm thick and supplied in 2 metre by 1 metre sheets. This closed cell sponge material does not absorb water so is suitable for making a watertight seal on boat hatches, lockers, car boots, enclosures, and cabinets.
We manufacture this product from high quality Expanded Neoprene which is a non-marking compressible material suitable for a wide range of every day and industrial applications. When compressed to approximately 30%, Expanded Neoprene will create a good long-term watertight seal without risk of compression set. This material has a good modular resistance to most substances including UV, air and ozone. Expanded Neoprene has a density of 130Kg/m3 and an operating temperature range between -40°C to +100°C.
Expanded Neoprene can be bonded onto most clean flat surfaces such as plastic, wood and metal. If there is a large amount of moisture or water present we recommend using a good quality contact adhesive such as our A262 (available from our website).
