Thermal conductive plastic pipes have broad prospects and high-end raw materials rely on imports

Thermal conductive plastic pipes are pipes that are extruded and modified by hot-melt blending of pipe-grade thermoplastic resin with good corrosion resistance and thermally conductive material micropowder with good corrosion resistance and high thermal conductivity. Currently, commonly used thermally conductive plastic pipes include random copolymer polypropylene (PP-R) pipes, heat-resistant polyethylene (PE-RT) pipes, cross-linked aluminum-plastic composite pipes, polybutylene (PB) pipes, etc.

Compared with traditional metal pipes, thermally conductive plastic pipes have the advantages of light weight, corrosion resistance, high compressive strength, hygiene and safety, small flow resistance, energy saving, metal saving, improved living environment, long service life, and easy installation.

Thermal conductive plastic pipes can be directly used as heat exchange tubes for soil heat source pumps, water source heat pump systems, ground radiant heating systems, etc. in the construction field. They can also be directly used for special industrial fluid transportation. They can also be welded and processed into different forms and structures. Heat exchangers are used in chemical, food, pharmaceutical and other industrial manufacturing fields.

With the continuous improvement of the technical level of my country’s thermally conductive plastic pipe industry and the development of downstream industries such as heat exchangers and heat exchange tubes, the market demand for thermally conductive plastic pipes in my country has shown a growing trend. According to the “2022-2026 In-depth Market Research and Investment Strategy Suggestions Report on Thermal Conductive Plastic Pipe Industry released by the Industrial Research Center, in 2021 The annual demand for thermally conductive plastic pipes in China exceeds 800,000 tons.

There are many companies in the thermally conductive plastic pipe industry in my country, including large comprehensive pipe companies such as Weixing New Materials, Zhongcai Investment, and Lesso Group, as well as larger professional floor heating pipe manufacturers such as Hebei Rita Pipe Materials and Aikang Group, as well as There are a large number of small and medium-sized manufacturers and small or family-run enterprises, and the competition is very fierce.

Industry analysts said that although China is a major producer of thermally conductive plastic pipes, its production and supply capabilities in high-end materials are relatively Weak, some thermally conductive plastic pipes in China need to be imported from foreign companies such as Dow, LG, LyondellBasell, SABIC, etc. Imported brands such as Dalin Company, LG Company, SK Company, DuPont, etc. occupy the domestic PE-TR pipe market. For about half of the market for special materials, only two domestic companies, PetroChina and Sinopec, have large-scale production capabilities.
