Outstanding Performance Flame Retardant Function Heat Shrink Tubing Dual Wall

 

High Insulation Heat Shrink Protective Tube for Cable Laying

SBRS-125H (3X)High Insulation Heat Shrink Protective Tube for Cable Laying 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.
