Low temperature thick dual wall heat shrink tubing
Heat shrink tubing description
Low temperature thick dual wall heat shrink tubing, is a cross-linked polyolefin tube that is extruded with an inner layer of adhesive. Low temperature thick dual wall heat shrink tubing, The inner layer of adhesive, with superior sealing capability, is also a buffer against mechanical strain. Dual wall heat shrink tubing is designed to provide superior sealing against water, corrosive gas and chemicals. Low temperature thick 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 and wire bundling etc.
