Polyethylene terephthalate (PET), also commonly known as polyester chips, PET Chips, PET Resin, is prepared by ester exchange between dimethyl terephthalate and ethylene glycol or by esterification between terephthalic acid and ethylene glycol to synthesize dihydroxyethyl terephthalate, and then polycondensation reaction. And it is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range, and its operating temperature can reach 120°C.

PET resin also has good electrical insulation properties, and its electrical properties are still good even at high temperature and high frequency. As a commonly used resin, PET resin has the characteristics of good creep resistance, fatigue resistance, wear resistance and dimensional stability, low wear and high hardness, and has the greatest toughness, electrical insulation properties among thermoplastics Well, less affected by temperature, but poor corona resistance.

PET Water Bottles

Bottle grade pet resin has a uniform crystal structure and narrow molecular weight distribution; non-toxic, odorless, glass-like transparency and luster; good impact toughness and high strength; low gas permeability (that is, good barrier performance), can Extend the shelf life of beverages; simple processing, small dimensional change or small creep under load; compared with glass, it has many characteristics of light weight and good safety.

The end use of bottle grade polyethylene terephthalate resin is primarily determined by intrinsic viscosity (IV). PET chips with IV 0.80 are mainly used in drinking water bottles and mineral water bottles. PET flakes with an IV of 0.85 are mainly used to make carbonated beverage bulk bottles and 3-5 gallon water bottles because these bottles should have good strength and high pressure resistance. PET resin bottle grade has the characteristics of low processing temperature, wide processing range, good transparency and high yield.

Fiber-grade PET chips are polymers with an amorphous structure. When the PET resin is heated to a certain temperature, its amorphous structure can be transformed into a crystal structure with a certain degree of crystallinity. The density is 1.33-1.38g/cm3. This product has heat resistance, good light resistance and acid resistance. It is not easy to react when it is in contact with oxidizing agents and reducing agents. However, it has poor alkali resistance, low hygroscopicity and poor electrical conductivity. .

According to the content of matting agent tio2, the textile or fiber grade polyester chips can be divided into: super bright (high gloss), glossy, semi-dull, (full) matte PET chips. In addition, there are cationic polyester chips. Fiber-grade polyester chips are suitable for spinning all kinds of polyester staple fibers and filaments, making various clothing fabrics, cords and woven paper filter nets, etc.

In general, high quality PET resin (silica and titania free) can be used to make PET films. Film grade polyester chips are usually available in super bright and additive (silica) varieties. It is characterized by excellent transparency, and because the gauge of the film is so thin that even the slightest raw material error can have a negative effect on the film quality. Its main applications are printing and lamination, metallization, embossing, holograms, thermal lamination.

1. Packaging industry

  • Food and beverage packaging. In the food and beverage industry, PET polyethylene terephthalate is the preferred material for making beverage bottles, including water, soft drinks and juice bottles. PET bottles are lightweight, transparent, shatterproof, and well sealed. They can effectively protect the contents and reduce the weight of the package, meeting the requirements of environmental protection and sustainable development. According to statistics, PET bottles have occupied more than 70% of the market share in this field.
  • Polyester film. Polyethylene terephthalate resin can also be made into polyester film for packaging materials, films, and tapes. Polyester film has excellent transparency, water resistance, oil resistance, and chemical stability, and can effectively protect the packaged items.
