Product Description

DW(3:1 4:1)

Dual wall, high-shrink-ratio, adhesive-lined flexible polyolefin tubing

DW (3:1 4:1) is a flexible, flame-retardant, dual wall, high-shrink-ratio, irradiated heat-shrinkable tubing manufactured by co-extrusion of polyolefin and hot-melt adhesive. Inner is hot-melt adhesive with good stickness and outer is flexible, irradiated cross-linked polyolefin. It is widely used to environmentally seal and protect interconnections, joints and components from fluids, moisture and corrosion. High shrink ratio allows for connector-to-cable sealing and makes it possible to repair most damaged cable jackets without removing connectors.
