Heat shrinkable tubes have a wide range of applications and the industry is developing well

Heat shrink tubing, also known as heat shrink sleeve and heat shrink tube, is a new environmentally friendly, halogen-free, flame-retardant casing made of polyolefin material. The inner layer of the heat shrinkable tube has the advantages of good adhesion, good sealing, and waterproofing, while the outer layer has the advantages of wear resistance, softness, insulation, and anti-corrosion. It is widely used in wires and cables, electronic equipment, metal pipelines, automobile wiring harnesses, and other fields. According to different base materials, heat shrinkable tubes can be divided into three categories: adhesive heat shrinkable tubes, PVC heat shrinkable tubes and PET heat shrinkable tubes.

The main production process of heat shrinkable tubes includes raw material preparation, molding, radiation cross-linking modification, expansion, packaging, etc. Molding and radiation cross-linking modification are key links in the production of heat shrinkable tubes and play a decisive role in their quality. At present, the mainstream molding methods of heat shrinkable tubes include injection molding and single-screw extrusion molding. Injection molding is suitable for producing heat shrinkable tubes of various shapes; single-screw extrusion molding is suitable for producing high-temperature heat shrinkable tubes and single-wall heat shrinkable tubes. tubes, medium-thick wall heat shrinkable tubes and other products. Radiation cross-linking modification means that the structure of raw materials is changed under the action of radiation cross-linking, which can effectively improve the wear resistance, aging resistance and other properties of heat shrinkable tubes.

Heat shrinkable tubes include adhesive heat shrinkable tubes, PVC heat shrinkable tubes and PET heat shrinkable tubes. The inner layer of adhesive-containing heat-shrinkable tubes is made of hot-melt adhesive and is widely used in electronic equipment, wires and cables and other products; PVC heat-shrinkable tubes have extremely strong heat-shrink properties and can be used as packaging materials; PET heat-shrinkable tubes are also Polyester heat shrinkable tubes are called polyester heat shrinkable tubes and have the advantages of being recyclable and non-toxic. In the context of environmental protection, PET heat shrinkable tubes are expected to become the mainstream product in the heat shrinkable tube market.

According to the “2023-2028 China Heat Shrink Tube Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Heat shrinkable tubes have a wide range of applications, including wires and cables, electronic equipment, metal pipelines, automobile wiring harnesses, etc. In the field of wires and cables, heat shrink tubes can be used to connect terminals and cable cores; in the field of electronic equipment, heat shrink tubes can be used as insulating coating materials; in the field of automotive wiring harnesses, heat shrink tubes can insulate automotive parts. Protective effects. Driven by market demand, the development of my country’s heat shrinkable tube industry has accelerated.

There are many heat shrinkable tube manufacturers in my country, and the market competition is fierce. Shenzhen Woer Nuclear Materials Co., Ltd., Tyco Electronics (Shanghai) Co., Ltd., Yonggu Group Co., Ltd., and Shenzhen Hongshang Material Technology Co., Ltd. are the main manufacturers of heat shrinkable tubes in my country.

Industry analysts said that with the rapid development of downstream industries, the demand for heat shrinkable materials in our country’s market will continue to be released, and heat shrinkable tubes As a segmented product of heat shrinkable materials, its market development space is broad. PET heat shrinkable tubes have environmental protection advantages and are expected to become the mainstream product in my country’s heat shrinkable tube market in the future. It is expected that in the future, as the technical level of local enterprises continues to improve, the development trend of my country’s heat shrinkable tube industry will continue to improve.
