Uses
Polyester fiber synthesis: It is an important monomer for the production of polyester fiber. Polyester fiber has the advantages of high strength, good elasticity, wear resistance, corrosion resistance, etc. It is widely used in clothing, home textiles, industrial fabrics and other fields.
Resin manufacturing: It is used to manufacture polyester resin, which can be further processed into various plastic products, such as plastic film, plastic bottles, plastic pipes, etc., which are widely used in packaging, building materials, electronics and other industries.
Film production: The polyester film produced has good transparency, mechanical properties and barrier properties, and can be used for food packaging, electronic and electrical insulation, photographic film and other aspects.
Polyester paint preparation: It is one of the raw materials for the production of polyester paint. Polyester paint has good decorative and protective properties and is often used for the coating of furniture, automobiles, ships, etc.
Engineering plastics field: It can be used to synthesize engineering plastics, improve the performance of engineering plastics, and make them used in high-end fields such as aerospace, automobile manufacturing, and electronic appliances.
Other aspects: It can also be used to produce plasticizer dioctyl terephthalate, and can also be used as various organic synthesis intermediates for the synthesis of polyamide and other chemicals.
