It has been nearly 20 years since China’s heat-shrinkable material products have formed industrialized production, and so far they have basically formed large-scale production. On the whole, the world's heat-shrinkable material market is still in a growth stage, and my country is no exception. The future demand for heat-shrinkable material products has huge potential. As China begins to enter the stage of heavy chemical industry, domestic industrial structure upgrades and international industrial transfers, it is expected that high-speed rail, automobile and power construction will become areas where China's heat shrinkable materials will grow at a faster rate in the future, which is expected to drive China's heat shrinkable materials industry. Enter a new round of high growth period.

High-speed rail heat-shrinkable materials are mainly used on high-speed rail boards, which can serve as insulation protection when transmitting electrical signals on the rail. In addition, the circuit protection of electric locomotives is also useful. According to the national "Twelfth Five-Year Plan", high-speed railway construction will reach a construction mileage of 16,000 and 30,000 kilometers in 2015 and 2020, respectively. According to the forecasts of Qianzhan.com, the market demand for heat-shrinkable materials for high-speed railways is It will reach 930 million and 1.75 billion in 2015 and 2020 respectively.

According to the "China's Heat-shrinkable Materials Industry Market Outlook and Investment Forecast Analysis Report"[1] data show that the current domestic heat-shrinkable materials market share for automobile manufacturing is still very low, only about 20%, and 80% of the global market Compared with the U.S. Raychem and Japan’s Sumitomo, with the domestic automotive industry certification and cost advantages, the market share of automotive heat-shrinkable tubing is expected to further increase. At present, domestically produced automotive double-wall thermal The price of shrink tubing is only 20%-50% of that of Raychem and Sumitomo of Japan. According to the current domestic supply situation analysis of the automotive industry, if all heat-shrinkable tubings for automobiles made in China are replaced, the average use value of each car is about 100-200 yuan, while the price of using foreign heat-shrinkable tubing It is 200-500 yuan. Assuming that the market share of heat-shrinkable tubing for automobiles in China increases to 40%, and the global output of 70 million units per year, the market space for heat-shrinkable tubing for automobiles in China will reach about 4.2 billion.

Power-type heat-shrinkable materials are mainly cable accessories, which account for about 1.3% of the power grid investment. Its market capacity is determined by the total power grid investment in the year and has certain volatility. At present, power-type heat-shrinkable materials are mainly used for medium and low-voltage cable accessories of 35KV and below, while high-voltage cable accessories are mainly prefabricated and cold-shrinkable cable accessories. It is estimated that medium and low voltage cable accessories account for about 40% of cable accessories. According to estimates, the national power grid investment in 2015 will reach 2.5 trillion yuan, of which cable accessories will be 32.5 billion, and the market space of medium and low voltage cable accessories will be 13 billion.
