Chlorinated polyvinyl chloride (CPVC), also known as perchlorethylene, refers to a new engineering plastic made by further chlorination modification of polyvinyl chloride (PVC). Chlorinated polyvinyl chloride appears as white or light yellow powder. It has the advantages of high dielectricity, good heat resistance, good mechanical properties, and resistance to chemical corrosion. It is widely used in building materials, pipes, electronics and electrical, automobile manufacturing, aerospace, and coatings. It is widely used in other fields.

PVC resin is the main raw material of chlorinated polyvinyl chloride. my country is one of the world’s major producers of polyvinyl chloride resin. In 2022, my country’s polyvinyl chloride resin production capacity will reach 29.24 million tons, accounting for nearly 50% of the world’s total production capacity. The sufficient supply of raw materials lays the foundation for the development of my country’s chlorinated polyvinyl chloride industry. According to the “2023-2028 China Chlorinated Polyvinyl Chloride (CPVC) Industry Market In-depth Research and Development Prospects Forecast Report span>” shows that my country’s chlorinated polyvinyl chloride output will reach 139,000 tons in 2022, a year-on-year increase of 21.6%.

The preparation methods of chlorinated polyvinyl chloride include gas-solid phase method, solvent method and suspension method. The gas-solid phase method, also known as the gas-solid phase chlorination method, refers to the direct chlorination reaction of polyvinyl chloride resin in a dry state to finally obtain the finished product. This method has the advantages of green environmental protection and short production cycle, and is suitable for continuous chemical production; the solvent method is the earliest method used to prepare chlorinated polyvinyl chloride, which easily causes environmental pollution and has been replaced by other emerging methods; the suspension method is the mainstream preparation method of chlorinated polyvinyl chloride, with low production cost and high quality of finished products. With advantages such as good quality, it is currently used in industrial production.

Chlorinated polyvinyl chloride has a wide range of applications, including building materials, pipes, electronics and electrical, automobile manufacturing, aerospace, coatings, etc. In the field of pipes, CPVC pipes are chlorinated polyvinyl chloride end products, which can be used as electroplating solution pipes, gas transportation pipes, thermochemical reagent transportation pipes, hot sewage pipes, etc. Benefiting from strong downstream demand, my country’s chlorinated polyvinyl chloride market continues to expand, reaching 2.13 billion yuan in 2022.

The global chlorinated polyvinyl chloride market is mainly concentrated in Europe, the United States and Japan, including Lubrizol of the United States, KANEKA of Japan, Denka-Sekisui of Japan, France Arkema and BASF are world-renowned chlorinated polyvinyl chloride manufacturers. Driven by technological innovation, the number of participants in my country’s chlorinated polyvinyl chloride market continues to grow, including Hangzhou Dianhua Group, Shanghai Chlor-Alkali Chemical, Xinjiang Tianye, Qilu Petrochemical, etc.

Industry analysts said that as a new engineering plastic, chlorinated polyvinyl chloride has the advantages of high dielectric properties and good heat resistance. , widely used in many fields. Benefiting from the sufficient supply of raw materials, my country’s chlorinated polyvinyl chloride output continues to grow. However, at present, there is still a gap in the quality of my country’s chlorinated polyvinyl chloride compared with overseas developed countries. Local companies mainly produce mid-to-low-end products. In the future, with the improvement of technological level, my country’s chlorinated polyvinyl chloride industry will develop in a high-end direction.
