PET (Polyethylene terephthalate) is a thermoplastic engineering plastic with excellent properties, and its full name is Polyethylene terephthalate. It has good transparency, wear resistance and chemical resistance, and has good mechanical properties and insulation properties. Based on these characteristics, PET is widely used in many fields:
1. packaging industry: PET is one of the main materials for the production of beverage bottles, such as mineral water bottles, carbonated beverage bottles, etc. It is not only transparent and beautiful, but also light weight, high strength, easy to process and low cost.
2. Textile industry: As an important part of synthetic fibers, PET is often used in the manufacture of clothing, carpets, ropes, etc. Its fiber products have good elasticity and wrinkle resistance.
3. Electronic and electrical fields: Due to its excellent electrical insulation properties, PET can be used to manufacture electronic product components such as film switches and circuit board substrates.
4. Medical field: PET film can be used to produce disposable medical device packaging materials to ensure transport and storage in a sterile state.
5. Automotive industry: In recent years, with the development of lightweight trend, PET composite materials began to be applied in automotive parts, such as car lampshades, bumpers and so on.
6. Construction industry: Membranes made from PET can be used in glass interlayers to improve safety and insulation.
