Rubber heat shrinkable tube

The outer layer of the double-wall heat-shrinkable sleeve is made of high-quality polyolefin alloy and processed by inner layer hot melt adhesive. After the product is formed, it is formed by cross-linking and continuous expansion by electron accelerator. The outer layer has the advantages of softness, low temperature shrinkage, insulation, corrosion resistance, wear resistance, etc. The inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering performance. Widely used in the wiring of electronic equipment, waterproof, anti-leakage, multi-strand wire harness sealing and waterproofing (such as home wiring harness, car wiring harness, etc.), sealing and waterproofing of wire and cable branches, corrosion protection of metal pipelines, repair of wire and cable, water pump and The submersible pump is wired and waterproof.

The double-wall heat shrinkable sleeve is produced by a polyolefin-based halogen-free flame retardant material and a hot melt adhesive double-layer coextrusion process. The outer layer is polyolefin with insulation, halogen-free flame retardant, low temperature shrinkage, etc.; the inner layer is hot melt adhesive with low melting point, good adhesion, waterproof sealing and mechanical strain buffering.

feature of product:

Heat shrinkable sleeve has excellent flame retardant and insulating properties, very soft and elastic, low shrinkage temperature and fast shrinkage. It can be widely used in wire connection, wire end treatment, solder joint protection, wire harness identification, resistance and capacitance insulation protection. , corrosion protection of metal rods or pipes, protection of antennas, etc. The linear polymer material forms a three-dimensional network crosslinked structure under the action of high energy rays. The crosslinked polymer material is greatly improved in terms of mechanical strength, temperature resistance, chemical solvent resistance, and aging resistance, and in particular, acid resistance and alkali resistance are greatly improved.
