CB-DWT(3000) is semi-rigid, flame retardant and adhesive-lined polyolefin heat shrinkable tubing, it is designed to meet automotive requirements for sealing and electrical insulation for wire splices, terminations and components. It can provides abrasion protection of wire splices and fluids and moisture proof, which help to protect the wire bundles from corrosion.
