The usage of PET bottle flakes

PET plastic bottles are widely used for packaging carbonated beverages, drinking water, fruit juices, enzymes and tea beverages, etc., as well as food and chemical industries, and pharmaceutical packaging.

The recycling of PET plastic bottles can not only solve environmental problems, but also serve as a new raw material resource to alleviate the contradiction of China's shortage of PET raw materials.

PET is non-toxic, has the greatest toughness among thermoplastics, has good transparency, is not easily broken, and has good chemical stability. It is suitable for packaging a variety of liquid or solid medicines. Weather resistance, chemical resistance, good stability, low water absorption, resistance to weak acids and organic solvents.

PET is a yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, abrasion resistance, good dimensional stability, low abrasion and high hardness, with the greatest toughness among thermoplastics: good electrical insulation, low temperature influence, but poor corona resistance.

PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, crystallization molding is brittle, and low heat resistance.

PET is mainly used for fibers, and a small amount is used for films and engineering plastics. PET fiber is mainly used in the textile industry. PET film is mainly used for electrical insulation materials, such as capacitors, cable insulation, printed circuit wiring substrates, and electrode slot insulation.

Another application field of PET film is film base and base tape, such as motion picture film, X-ray film, audio tape, electronic computer tape and so on. PET film also uses vacuum aluminum to make metallized films, such as gold and silver wires, micro capacitor films, etc.
