NDW is a semi flexible dual wall heat shrinkable sleeving. As the sleeving shrinks, the inner adhesive lining melts and flows to encapsulate the components contained within, providing a permanent moisture barrier.

The versatility of this product for protecting cable jackets, wire splices or electrical components is further enhanced by the 3:1 and 4:1 shrink ratios, so that only a few sizes are required for a comprehensive range of diameter applications. NDW is available in a range of colours both as 1.2 mtr lengths and as continuous reels for certain sizes.
