        Dual wall Heat Shrink tube

        Dual wall Heat Shrink tube

        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.
         

        • Features/Benefits

        ·Shrink ratio: 3:1, 4:1.

        ·Environmentally seals and protects components, joints and interconnections from fluids, moisture and corrosion.

        ·Good mechanical, electrical and chemical properties.

        ·Adhesive has good stickness and bonds to a wide variety of plastics, rubbers and metals.

        ·Conform to RoHS and Sony-ss00259 environmental directive.

        • Operating Temperature Range

        ·Operating temperature range: -55℃~110℃

        ·Minimum shrink temperature: 80℃
