Application areas:
It is mainly used for insulation protection of medium and low voltage cable terminals or intermediate joints, as well as corrosion protection and wear resistance of various pipelines.
Product Description
Product Introduction:
Semi-rigid adhesive-lined inner wall tubes are composed of two layers: a semi-rigid polyolefin outer layer and a heat-shrinkable adhesive inner layer. The product provides both insulation and waterproof sealing. It is mainly used for insulation protection of medium and low voltage cable terminals or intermediate joints, as well as for corrosion protection and wear resistance of various types of pipes.
Features:
Heat shrink ratio : 3:1
Initial shrinkage temperature: ≥ +70 ℃
Complete shrinkage temperature: ≥ +125 ℃
Operating temperature: -45 ℃ ~ +110 ℃
UV resistant and waterproof
Environmental Standards: RoHS
Standard color: Black (other colors can be customized)
