features

PET is one of those plastics that are an important part of your daily life. It is an important commercial polymer that has applications ranging from packaging, fabrics, films, car parts, electronics ... and many more. You can find this famous transparent plastic around you like a bottle of water or a soda container.

 

Polyethylene terephthalate (PET or PETE) is a commonly used thermoplastic polymer that belongs to the family of polyester polymers. Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance and dimensional stability.

 

PET is one of the most recycled thermoplastics, and has the number «1» as a recycling symbol.

 

Thanks to the good electrical insulation properties, high structural and dimensional stability, polyethylene terephthalate is widely used in the electrical and electronic industry. It is an effective polymer to replace metal and thermostable molds in applications such as: electrical encapsulation, solenoids, smart meters, photovoltaic parts, solar junction boxes, etc. The outstanding flow characteristics of the polymer allow design freedom and miniaturization to produce high performance parts.

 

PET is being used successfully in many applications in the automotive industry. It is currently being used in the following applications: wiper arms and gears, headlight retainer, motor cover, connector housings.

Applications

Polyethylene terephthalate is used in several packaging applications, as mentioned below:

  • Because polyethylene terephthalate is an excellent barrier material against water and moisture, plastic bottles made of PET are widely used for mineral water and soft drinks.
  • Its high mechanical strength makes poly (ethylene terephthalate) films ideal for use in tape applications.
  • PET packaging applications a material of choice for food packaging applications
  • The non-oriented PET sheet can be thermoformed to make packing trays and ampoules
  • Its chemical inertia, along with other physical properties, has made it especially suitable for food packaging applications.
  • Other packaging applications include rigid cosmetic bottles, microwave containers, transparent films, etc.

 

PET monofilament is mainly used for the manufacture of screen printing mesh fabrics, filters for oil and sand filtration, bracing wires for agricultural applications (greenhouses, etc.), knitting / knitting belts, filter cloths and other applications Similar industrial.

 

PET has wide applications in the textile industry. Polyester fabrics are strong, flexible and offer an additional benefit of less wrinkles and shrinkage over cotton. Polyester fabrics are lightweight, reduce wind, are drag resistant and more tear resistant.
