Material:
Outer: irradiation crosslinked modified polyolefin material
Inner layer: hot melt adhesive
(Single-wall type thick-walled tube does not involve the inner layer)
Shrink ratio: 3.5: 1 4: 1

Features:

  • High shrink ratio, the greater the diameter of the quilt was coverage;
  • Black sleeving, has excellent UV resistance;
  • semi-rigid walled polyolefin material has excellent electrical insulation propertiesand mechanical protection properties;
  • Minimum fully shrink temperature: 135 ℃.Application: High magnification of the polyolefin heat-shrinkable tubing material with good electrical insulation properties and mechanical protection properties, its high rate shrinkage characteristics, particularly suitable for a wide range of sizes harness connection or component connection, the thicker type of wall thickness characteristics, especially for electrical insulation protection and mechanical protection, inner layer of hot melt adhesive in high-voltage power cable connected to the connecting member can play a waterproof seal.
