Product Details
Place of Origin: | Guangdong, China | Brand Name: | KOSOO | Model Number: | DW(3:1.4:1) |
Type: | Insulation Sleeving | Material: | Other, polyolefin | Application: | Low Voltage |
Rated Voltage: | 600V | Tensile Strength: | 9.0MPa Min. |
Product Description
Polyolefin Dual wall heat shrinkable tube DW(3:1)
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 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 mechnical, 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℃
·Minimum full recovery temperature: 110℃
