Low Temperature Thick Adhesive-lined Dual Wall Heat Shrink Tube
Description:
SBRS-125G(3X) LS 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:
²Shrink ratio:3:1
²Flexible, flame retardant outer layer, environmentally friendly, low temperature shrinkable, UV resistant
²Shrink temperature:60C~1105ºC
²ROHS compliant
²Continuous operating temperature :--45 °c~ 125°c
²Standard colors: black, other colors are available on your request
