my country’s polyester chip production continues to rise and export scale continues to expand

Polyester chips, also known as polyethylene terephthalate and polyester resin, refer to polyester raw materials produced through polymerization, which are processed into flaky particles of about 4*5*2 mm. Polyester chips appear as colorless and transparent particles. They have the advantages of excellent electrical insulation, good physical and mechanical properties, and no odor. They are widely used in textiles, packaging materials and other fields. According to different uses, polyester chips can be divided into three types: film-grade polyester chips, fiber-grade polyester chips and bottle-grade polyester chips.

The production process of polyester chips includes transesterification method (DMT method) and direct esterification method (PTA method). The transesterification method is the earliest process route for polyester chips. It uses dimethyl terephthalate and ethylene glycol as the main raw materials. Polyester chips are generated through the transesterification reaction. This method will produce a large amount of formaldehyde during the production process, which is easy to Cause environmental pollution. The direct esterification method is the mainstream process route for polyester chips. It uses purified terephthalic acid as the main raw material. It has the advantages of short reaction time and low raw material consumption, and is suitable for large-scale production.

According to the “2022-2027 China Polyester Chip Industry Market Supply and Demand Research Consultation Report released by the Industrial Research Center, polyester chips It has a wide range of applications, including textiles, packaging materials, medical and health care, household appliances, automobile manufacturing, engineering plastics, etc. In recent years, with the rapid economic development and the continuous improvement of national living standards, the market demand for packaging materials has become increasingly strong, driving the rapid development of my country’s polyester chip industry. In 2021, my country’s polyester chip production reached 16.039 million tons, a year-on-year increase of 7.2%. Zhejiang, Shanghai, Guangdong, Fujian and Jiangsu are the main polyester chip production areas in my country, with Zhejiang’s output ranking first in my country.

Benefiting from the mature development of production technology, my country’s polyester chip production capacity has rapidly expanded and output has continued to grow. While meeting local market demand, it has further developed overseas markets. Against this background, the scale of my country’s polyester chip exports continues to expand. According to statistics from the General Administration of Customs of China, my country’s polyester chip exports in 2021 will reach 672,000 tons, a year-on-year increase of 72.1%; imports will reach 378,000 tons, a year-on-year increase of 13.8%.

my country’s polyester chips market is highly competitive and the industry is highly concentrated. Zhejiang Juhua Co., Ltd., Jiangsu Shuangxing Color Plastic New Materials, Jiangsu GCL Energy Technology, Zhejiang Wankai New Materials, etc. are the leading polyester chip companies in my country. According to the financial report of Juhua Co., Ltd., the company achieved operating income of 17.99 billion yuan in 2021, a year-on-year increase of 12.0%.

Industry analysts said that my country is a major producer of polyester chips. As local companies continue to accelerate the optimization of industrial structure layout, it is expected that in the next period Over time, my country’s polyester chip production capacity will maintain a steady growth trend. As production technology matures, the output and quality of polyester chips in my country continue to improve. At present, local companies have competitive advantages and voice in the global market.
