Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
The majority of the world's PET production is for synthetic fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).
PET consists of polymerized units of the monomer ethylene terephthalate, with repeating (C10H8O4) units. PET is commonly recycled, and has the digit as its resin identification code (RIC).
Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The semicrystalline material might appear transparent (particle size less than 500 nm) or opaque and white (particle size up to a few micrometers) depending on its crystal structure and particle size.
The monomer bis(2-hydroxyethyl) terephthalate can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct (this is also known as a condensation reaction), or by transesterification reaction between ethylene glycol and dimethyl terephthalate (DMT) as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with water as the byproduct.
PET (Polyethylene Terephthalate) Resin is cream or pale-yellow crystal, with smooth and shiny surface. Resistance to creep deformation, fatigue resistance, abrasion resistance and dimensional stability are perfect. Small wear and tear but high hardness, its toughness is the largest in thermoplastic. The electrical insulation of PET is perfect and little be affected by temperature, however, poor corona resistance. PET is non-toxic, weather resistance, and anti-chemical stability is very good. PET is low water absorption, resistance to weak acids and organic solvents. Intolerance of hot water immersion and alkali.
Feature:
1.Oil resistant, fat resistant, acid resistant, alkali resistant, resistant to most solvents.
2.Excellent resistance performance of high and low temperature.
3.Non-toxic, tasteless, health and safety.
4.Transparent, UV blocking, good glossiness.
