The materials of heat shrinkable sleeves are mainly plastics, including PVC, ABS, EVA, PET, etc.
Heat shrink sleeve is a kind of heat shrink packaging material that shrinks when exposed to heat. According to the material, it can be divided into PVC heat shrink sleeve, PET heat shrink sleeve and radiation cross-linked PE heat shrink sleeve. Pipe, 10KV high voltage busbar protection heat shrinkable sleeve, 35KV high voltage busbar protection heat shrinkable sleeve, glue-containing double wall heat shrinkable sleeve, imitation wood grain heat shrinkable sleeve.
Heat shrink tubing has flame retardant, insulating, and temperature resistance properties. Heat shrink tubing is a special polyolefin heat shrink tubing, also called EVA. It is soft and elastic. It will shrink when heated (125℃).
Extended information
The outer layer of the adhesive double-wall heat shrinkable sleeve is made of high-quality polyolefin alloy and the inner layer is made of hot melt adhesive. After the product is formed, it is cross-linked by electron accelerator irradiation and continuously expanded.
The outer layer has the advantages of softness, low-temperature shrinkage, insulation, anti-corrosion, and wear resistance, while the inner layer has the advantages of low melting point, good adhesion, waterproof sealing, and mechanical strain buffering properties.
Widely used in waterproofing and air leakage prevention for wiring of electronic equipment, sealing and waterproofing of multi-strand wiring harnesses (such as home wiring harnesses, automobile wiring harnesses, etc.), sealing and waterproofing of wire and cable branches, and anti-corrosion protection of metal pipelines. Repair of wires and cables, waterproofing of water pumps and submersible pumps, etc.
Double-wall heat shrinkable sleeves are produced using polyolefin halogen-free flame retardant materials and hot melt adhesive double-layer extrusion process. The outer layer is made of polyolefin, which has the characteristics of insulation, halogen-free flame retardant, and low-temperature shrinkage; the inner layer is made of hot-melt adhesive, which has the advantages of low melting point, good adhesion, waterproof sealing, and mechanical strain buffering.
