my country’s polyvinylidene chloride production has gradually increased and exports have increased

Polyvinylidene chloride (PVDC) is a polymer with high barrier properties. It has a head-to-tail linear polymer chain structure, strong cohesion between molecules, and high crystallinity. The melting temperature of polyvinylidene chloride is between 198 and 205°C, and it mostly appears as a white porous powder under normal temperature and pressure. Due to its strong polarity, polyvinylidene chloride is insoluble in general solvents at room temperature.

After years of development, my country’s polyvinylidene chloride product types have become increasingly rich, which can be roughly divided into polyvinylidene chloride emulsion, polyvinylidene chloride resin, etc. Among them, polyvinylidene chloride emulsion is mostly used to produce PVDC coated films; polyvinylidene chloride resin is mostly used to produce PVDC shrink film, PVDC composite film, PVDC casing film, PVDC cling film, etc.

At this stage, the preparation process of polyvinylidene chloride has been basically mature and can be roughly divided into emulsion polymerization, suspension polymerization, etc. The emulsion polymerization method has been gradually eliminated by the market due to defects such as large residual amounts of additives and complex production processes. The suspension polymerization method has become the mainstream process for producing polyvinylidene chloride due to its advantages such as low production cost and excellent overall product performance.

From the perspective of the industrial chain, the upstream of my country’s polyvinylidene chloride industrial chain is mainly the raw material industry, providing hydrogen, chlorine, caustic soda and other raw materials; the midstream is mainly the polyvinylidene chloride production industry, responsible for the production, Manufacturing link; downstream mainly has application fields. Polyvinylidene chloride is mostly used in chemical packaging, food packaging, pharmaceutical packaging, electronic product packaging and other fields.

Polyvinylidene chloride has the advantages of corrosion resistance, flame resistance, oxygen resistance and moisture resistance, and has excellent barrier properties to gas, oil and other products. At present, polyvinylidene chloride has become the plastic packaging material with the best comprehensive performance in terms of barrier properties. According to the “Polyvinylidene Chloride (PVDC) Industry In-depth Market Research and Investment Strategy Suggestions Report 2023-2027” released by the Industrial Research Center shows that driven by downstream market demand, my country’s polyvinylidene chloride production capacity has gradually expanded and output has increased. In 2022, my country’s polyvinylidene chloride production will be 130,700 tons, a year-on-year increase of 12.91%.

From the perspective of import and export, in recent years, my country’s polyvinylidene chloride production capacity has gradually expanded, and the export scale has increased. According to data released by the General Administration of Customs, in 2022, my country’s polyvinylidene chloride export volume was 5,200 tons, a year-on-year increase of 119.13%; the export value was US$16 million, a year-on-year increase of 225.88%.

Industry analysts said that the main foreign polyvinylidene chloride companies include Dow Chemical, Japan’s Kureha, Solvay, and Asahi Kasei etc. Domestic polyvinylidene chloride companies mainly include Juhua Co., Ltd., Juhua Chemical Co., Ltd., etc. Among them, Juhua Co., Ltd., as the leading enterprise of polyvinylidene chloride in my country, has relatively advanced production technology and large production capacity. With the rapid development of my country’s polyvinylidene chloride market, Juhua’s operating income has gradually increased. According to data in the company’s annual report, Juhua’s operating income in 2022 will be 21.489 billion yuan, a year-on-year increase of 19.48%.
