KOSOO DW(3:1, 4:1)
Dual wall, high-shrink-ratio, adhesive-lined flexible polyolefin tubing
Application
KOSOO 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 srink ratio allows for connector-to-cable sealing and makes it possible to repair most damaged cable jackets without removing connectors.
Features/Benefits
1Shrink ratio: 3:1, 4:1.
2Environmentally seals and protects components, joints and interconnections from fluids, moisture and corrosion.
3Good mechnical, electrical and chemical properties.
4Adhesive has good stickness and bonds to a wide variety of plastics, rubbers and metals.
5Conform to RoHS and Sony-ss00259 environmental directive.
