The application scope of heat shrinkable materials is gradually covering high-tech fields, and the industry development trend is improving.

Heat shrinkable materials, also known as polymer shape memory materials, refer to polymer materials such as polyethylene and polyvinyl chloride as base materials. The base materials are interlaced with functional additive materials such as antioxidants and flame retardants through radiation processing technology. A smart material created by combining. Heat shrinkable materials generally have good electrical insulation properties, flame retardant properties, corrosion resistance, aging resistance, temperature resistance and unique memory effects. They are often used to make heat shrinkable pipes, membrane materials, special-shaped materials and other materials. Electronics, electricity, communications, energy, aerospace, precision instruments, national defense industry, rail transportation and other fields.

Heat shrinkable materials are mainly used as protective materials due to their good properties. They are heated and shrunk to cover the outer surface of objects, thereby achieving good insulation, sealing, moisture-proof, wear-resistant and protective effects. In the automotive field, heat shrinkable materials are mainly used as protective materials for instrument wiring harnesses, door wiring harnesses, oil pipelines, brake system pipes and other components; in the nuclear energy field, they are mainly used for the connection and connection of power cables, measurement cables, low-voltage control cables and other components. Protection scene is one of the important insulation materials required for the safe construction of nuclear power plants.

According to the“China Heat Shrink Material Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center , my country’s heat shrinkable material market size will reach 20.57 billion yuan in 2022. As a type of polymer material with excellent comprehensive properties, heat shrinkable materials are currently expanding in their application fields as their advantages continue to highlight and domestic high-tech industries continue to emerge. In the future, under the background of continuous upgrading of the domestic industrial structure, the rapid development of high-tech industries such as nuclear energy, new energy vehicles, and high-speed rail will become the main driving force for the heat shrinkable materials market to accelerate towards a high-growth stage. It is expected that from 2023 to 2028, my country’s heat shrinkable material market will grow at an average annual compound growth rate of about 7.5%.

Research on heat shrinkable materials in my country started in the 1950s, and started the industrialization process in the late 1980s. After continuous in-depth research and development in recent years, the gap between the product quality of local companies and leading foreign companies has gradually narrowed, occupying market share is constantly expanding. Domestic heat shrinkable material companies mainly include Wall Nuclear Materials, Changyuan Electronics, Yunlin Applied Materials, Nord Co., Ltd., Hongshang Materials, Yonggu Group, Kaiheng Enterprise, Sanlian Heat Shrink, etc.

Industry analysts said that my country currently has many leading companies in the high-end heat shrinkable material market, and at the same time, as the leading companies’ technology continues to Upgrading, its market share is constantly expanding, and the industry is showing a good development trend. But overall, in my country’s heat shrinkable material industry, small and medium-sized enterprises still account for the majority, and they mainly focus on the mid-to-low-end market, and there are fewer companies in the high-end market. In the future, leading local companies will need to seize the development opportunities of domestic high-tech industries. , accelerating the layout of the high-end heat shrinkable material market.
