Product Description
Dual Wall Heat Shrinkable VW-1 Flammability


Description
SBRS-125G(2X)(3X)(4X), Dual Wall Heat Shrinkable VW-1 Flammability, is a cross-linked polyolefin tube that is extruded with an inner layer of adhesive. 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. 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.


Features
²  Standard:UL 224
²  Shrink ratio:2:1 3:1 4:1
²  Flame retardant out layer, environmentally friendly,UV resistant
²  Shrink temperature:70°C~125ºC
²  Continuous operating temperature:-45ºC~125ºC
²  RoHS compliant
²  Standard colors:black,other colors are available on request
