The Introduction of Heat Shrink Tubing

The Introduction of Heat Shrink Tubing

The Waterproof Heat Shrink Tubing is a special polyolefin heat-shrinkable sleeve. The outer layer of Waterproof Heat Shrink Tubing is made of high-quality soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, wear resistance, etc., and the inner layer of Waterproof Heat Shrink Tubing has advantages of low melting point, waterproof sealing and high adhesion, etc.

Performance: Polyolefin Heat Shrink Tubing has the functions of high temperature shrinkage, softness, flame retardancy, insulation and corrosion resistance. Polyolefin Heat Shrink Tubing is widely used in the insulation protection of various wire harnesses, solder joints, and inductors, and the antirust and anticorrosion of metal pipes and rods. Voltage level 600V.As the temperature goes from low to high, the polymer material will go through the glass state-high elastic state, the performance of the glass state is close to that of plastic, and the performance of high elastic state is close to that of rubber.The material used for heat shrink tubing is glassy at room temperature and becomes highly elastic when heated.Use: Heat the Polyolefin Heat Shrink Tubing to a high elastic state during production, apply a load to make Polyolefin Heat Shrink Tubing expand, and cool it rapidly while maintaining the expansion, so that it enters a glass state, and this state is fixed. Once heated during use, Polyolefin Heat Shrink Tubing will return to a high elastic state, but when the load is gone, it will retract.Shrink ratio: 2:1;Shrinkage temperature: 84℃～120℃;Working temperature: -55℃～125℃;Fire rating: VW-1

Wear Resistance Heat Shrink Tubing classification

PVC heat shrinkable sleeve
The PVC heat-shrinkable sleeve has a special function of shrinking when heated, and it can shrink when heated above 98°C, which is convenient to use. The products are divided into two series of 85°C and 105°C according to the temperature resistance, and the specifications are Φ2-Φ200. The products comply with the EU RoHS environmental protection directive. Used in electrolytic capacitors and inductors, the product has good high temperature resistance and no secondary shrinkage, and can be printed instead. It is used for single and combined packaging of various rechargeable batteries, and can design and print patterns on behalf of customers, and can also cut them on behalf of customers. It is used for the outer coating of various curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, telescopic rods, garden tools, poles and other tubular items.PVC Waterproof Heat Shrink Tubing can also be used for low-voltage indoor busbar copper bars, connectors, wiring harness identification, and insulation coating. High efficiency, less investment in equipment, and low overall cost. It is a new generation of packaging materials for lighting, LED pin wrapping, and guitar and packaging bottle wrapping. Whether it is for civilian, vehicle or military use, it is the best choice.
PET Waterproof Heat Shrink Tubing
PET Waterproof Heat Shrink Tubing (polyester heat shrinkable tubing) greatly surpasses pvc heat shrinkable tubing in terms of heat resistance, electrical insulation, and mechanical properties. More importantly, PET Waterproof Heat Shrink Tubing is non-toxic, easy to recycle, and harmless to the human body. And the environment will not produce toxic effects, more in line with environmental protection requirements.
The environmental protection performance of PET heat shrinkable tube is higher than the EU RoHs directive standard, and can meet the Sony SS-00259 environmental protection standard. Free of cadmium (Cd), lead (Pb), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBBEs/PBDEs), polychlorinated biphenyls (PCBs), polychlorinated terphenyls ( PCT), polychlorinated naphthalene (PCN) and other Class 1 environmental management prohibited substances, are the outer coating of electrolytic capacitors, inductors and other electronic components, high-end rechargeable batteries, toys and medical equipment, which can fully meet the export requirements.

Adhesive Polyolefin Heat Shrink Tubing
The outer layer of the adhesive-containing double-wall Polyolefin Heat Shrink Tubing is made of high-quality polyolefin alloy, and the inner layer is compounded with hot-melt adhesive. After the product is formed, it is cross-linked and continuously expanded by electron accelerator irradiation. The outer layer has the advantages of softness, low temperature shrinkage, insulation, anti-corrosion, wear resistance, etc., and the inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering performance. Widely used in wiring waterproof and air leakage prevention of electronic equipment, sealing and waterproofing of multi-strand wiring harnesses (such as household wire harnesses, automobile wiring harnesses, etc.), sealing and waterproofing of wire and cable branches, anti-corrosion protection of metal pipelines, repairing of wires and cables, water pumps and Submersible pump wiring waterproof and other occasions.
The double-wall Polyolefin Heat Shrink Tubing is produced by the double-layer co-extrusion process of polyolefin halogen-free flame-retardant materials and hot-melt adhesive. The outer layer is polyolefin, which has the characteristics of insulation, halogen-free flame retardant, and low-temperature shrinkage; the inner layer is hot-melt adhesive, which has the advantages of low melting point, good adhesion, waterproof sealing and mechanical strain buffering.
