Polyethylene Terephtalate (PET)

Polyethylene terephthalate (PET) is a thermoplastic composed from polymerization of ethylene glycol and terephthalic acid, it has high hardness and high abrasion resistance, it is resistant to ultra violet light, X rays, and γ-rays radiation. PET is resistant to organic solvent ; such as acetone, benzene, toluene, Trichloroethane, and oil, it also have good resistant to oxidant such as peroxide and sodium hydroxide Be aware that PET have relatively higher water absorption, also its chemical resistance properties reduces, when its temperature and humility increases. Although there are study on the risk of toxic migration from PET at higher temperature, but so far it have not proven any hazard risk to human body.
