According to the China PETG Market Forecast and Strategic Research Report (2022) released by Limu Information Consulting, PETG is a copolymerized product obtained by replacing some ethylene glycol with other glycols (comonomers) during PET synthesis. Replacing ethylene glycol with comonomers will reduce the melting point of copolyesters, increase the glass transition temperature and decrease the crystallinity. PETG products have high transparency, excellent thermoforming performance, toughness, weather resistance, ease of processing, and chemical resistance. They are suitable for forming thick wall transparent products, and are ideal substitutes for existing polycarbonate and polymethyl methacrylate materials.
PETG is an environment-friendly material, which meets the requirements of food contact management, is non-toxic and harmless to human beings and the natural environment, does not produce unpleasant smell during thermal processing, does not release toxic gas during incineration, and does not pollute groundwater after landfill treatment. With the improvement of environmental protection requirements in China, PETG products are facing broad development opportunities.
The global enterprises that can produce PETG copolyester include Eastman Company, SK Company in South Korea, Liaoyang Petrochemical and China Resources Chemical Materials Technology Co., Ltd. in China.
Eastman has many PETG brands, which can be used to produce sheets, shrink films, injection molded products, etc. SK Company mainly produces three brands of products: Sky Green PETG S2008, Sky Green PETG K2012 and Sky Green KNl00.
In 2021 and before, Eastman Company of the United States will have a market share of 70% - 80% in China's PETG market, especially in extrusion molding and extrusion blow molding. SK Company of South Korea has a market share of 10% - 20% in China. Because its market price is lower than Eastman Company, it has a higher market share in injection molding. PETG of domestic manufacturers only accounts for about 5% of the domestic market.
In the first half of 2022, Liaoyang Petrochemical will open the whole industrial chain of PETG copolyester, develop 10 new customers, and sell about 50000 tons of PETG copolyester in the first half of 2022; Another enterprise, China Resources New Materials PETG Phase I with an annual output of 50000 tons, will be put into production in the first half of 2022.
In 2021, China's PETG total polyester output will be 18198.6 tons, with a year-on-year growth of 25.7%; In the first half of 2022, China's PETG polyester output will be 52200.0 tons, with a year-on-year growth of 473.7%.
At present, the domestic development of PETG copolyester chips and their plastic products is still at the initial stage, and the processing experience and product design are still weak. The product cost is high, and the product added value is not high. In addition to the product processing technology is not mature enough, the new products developed at present have not been widely recognized by the market. It is believed that with the continuous deepening of technology research and development and the continuous maturity of production technology, the cost performance of PETG copolyester will be improved by one step.
