December 18, Liaoyang Petrochemical Company independent research and development of new products PETG copolyester successful trial production of raw materials, all performance indicators have reached similar foreign product standards, breaking the monopoly of foreign technology, making China the world's third oil with independent intellectual property rights And PETG copolyester industrial production enterprises, to fill the blank of such products.
PETG is a non-crystalline copolyester with glass-like transparency and good gloss, as well as excellent chemical resistance, impact resistance and environmental protection. Its products are highly transparent, impact resistance, processing and molding excellent performance, especially for production of thick-walled transparent article, can be widely used for plates, sheets, high performance shrink films, bottles, and profiles, and other fields.
PETG copolyester trial production of raw materials for Liaoyang Petrochemical Company to the film polyester, functional polyester, high-end polyester development has laid a solid foundation.
In recent years, Liaoyang Petrochemical Company has been committed to the research and development of polyester research results and transformation, through the development of differentiated, characterized, high-end new products to enhance the core competitiveness of enterprises. 100,000 tons / year PETG copolyester industrialization pilot project PETG copolyester was also independently researched and manufactured by PetroChina. In October 2012, it first produced qualified industrial PETG copolyester test products, successfully breaking the gap between Eastman in the United States and SK in South Korea Of the technical monopoly.In October 2014, PETG copolyesters key raw materials 1, 4-cyclohexane dimethanol intermediate industrial test to achieve a breakthrough, and completed the preparation of 10,000-ton process package, which formed from the raw materials to the product Downstream integration technology.
