Product Overview
Description
UL Coating adhesive insulation Heat shrink tube
Model: G-3 & 4
Dual wall, high-shrink-ratio, adhesive-lined flexible polyolefin tubing
1) Application
G-3&4 is a flexible, irradiated heat-shrinkable, flame-retardant, dual wall, high-shrink-ratio, tubing manufactured by co-extrusion of polyolefin and hot-melt adhesive, adhesive coated in the innerwall, with good stickness and outer is flexible, irradiated cross-linked polyolefin. It is widely used to environmentally seal and protect interconnections, jointsand 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.
2) 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 European RoHS environmental directive.
3) Operating Temperature Range
Operating temperature range: -55℃~110℃
Minimum shrink temperature: 80℃
Minimum full recovery temperature: 110℃
4) Specifications/Standards
UL224,UL Approval,125℃ 600V
