Product Description
Dual Wall Polyolefin Heat Shrink tube
Adhesive Heat Shrink Sleeving, Polyolefin Dual Wall Tubing the outer layer makes by polyolefin PE material which is flame-resistant, semi-hard and wear-resistant. High shrink ratio, good adhesion performance, and the physical &chemical properties are also good. So it can protect the wire harness very well.
Adhesive Lined Polyolefin Heat Shrink Tubing the inner PA hot melt adhesive :High temperature resistance, waterproof, damp-proof, corrosion resistance.
Dual Wall Tubing apply to automobile wire harness, household wire harness, wire and cable branch, metal pipeline where need insulated protection.
Dual heat shrink tube, Waterproof Dual Wall Tubing is characterized by halogen free, Flame resistant. Dual Walled Electrical Heat Shrink Tubing ,This kind of Heat Shrink Tube is environmentally friendly, soft, Insulation, shrink at low temperature. Voltage level of this heat shrink tube is 600V.
Dual Wall Heat Shrink Tubing typical applications include environmental sealing of in-line splices, sealing and strain relief of connectors and terminals, abrasion protection and electrical insulation of automotive wiring harness splices and valuable components, fleet & marine sealing & protection.
