Description
Our Plain Expanded Neoprene/EPDM Sponge Strip is a versatile, non-adhesive closed-cell rubber strip supplied in convenient 10-metre rolls. Available in a choice of widths and thicknesses, it is suitable for sealing, cushioning, insulation, vibration reduction and gap-filling applications.
The closed-cell construction provides excellent resistance to water absorption, air, weathering and UV exposure. It also offers good resistance to acids and remains flexible across a wide operating temperature range. The strip can be easily cut to the required length using a sharp knife or scissors.
Please note: This product is plain and does not have a self-adhesive backing.
