Introduction
  Description


SBRS-125G (3X) (4X)-Aisacross-linked polyolefin tube that is extruded with an inner layer of adhesive.The inner layer of adhesive, with superior sealing capability, is also a bufferagainst mechanical strain. Dual wall heat shrink tubing is designed to providesuperior sealing against water, corrosive gas and chemicals. Typicalapplications include environmental sealing of in-line splices, sealing andstrain relief of connectors and terminals, abrasion protection and electricalinsulation of automotive wiring harness splices and valuable components, fleet& marine sealing & protection and wire bundling etc. 


Features


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