79793-81-0 - Introduction
Adipate-1, 4-cyclohexanedimethanol-neopentyl glycol-phthalic anhydride-propane trimethanol copolymer, commonly known as PCTG copolymer. The following is an introduction to the properties, uses, preparation methods and safety information of PCTG copolymers:
1. Nature:
PCTG copolymer is a thermoplastic polyester with good rigidity and strength. It has excellent chemical resistance, heat resistance and impact resistance. It is also transparent and has good electrical insulation properties.
2. Use:
PCTG copolymers are widely used in plastic products and packaging materials. Due to its excellent mechanical properties and chemical resistance, it is often used in the manufacture of durable consumer goods, such as beverage bottles, food containers, cosmetic bottles and medical devices. In addition, PCTG copolymers are also used in the electronic field, such as battery cases, circuit boards and optical components.
3. Preparation method:
The preparation of PCTG copolymer is mainly achieved by polymerization reaction. The raw materials of adipic acid, 1,4-cyclohexanedimethanol, neopentyl glycol, phthalic anhydride and propane trimethanol were mixed and then subjected to transesterification and polycondensation under heating. Specific conditions and operations may be determined according to the specific process and reaction conditions selected.
4. Safety Information:
The PCTG copolymer is considered to be a relatively safe material suitable for applications in contact with food and beverages. It meets food safety standards and does not produce harmful substances dissolved under general conditions of use. However, specific safety assessments and tests are required for specific applications and treatments. When using PCTG copolymer, high temperature, chemical substances and mechanical damage should be avoided to ensure its performance and safety.
Summary:
PCTG copolymer is a thermoplastic polyester material with excellent performance, which is widely used in the field of plastic products and packaging materials. It has good mechanical properties, chemical resistance and transparency, and can be used to manufacture durable consumer goods and electronic products. The preparation of PCTG copolymer is mainly through polymerization reaction, and the specific process can be adjusted according to needs. When using PCTG copolymer, attention should be paid to safe use and handling methods to ensure its performance and safety.
