Polyethylene terephthalate (PET or PETE) has a much stronger, stronger, brighter and harder structure compared to other thermoplastics. At the same time, it is resistant to many solvents. Polyethylene terephthalate, obtained by using the polymerization technique of ethylene glycol and terephthalic acid, is melted and turned into a sticky material that can be processed into plastic after the process. This resulting material and product is used in the production of disposable water bottles called PET bottles. The resistance rates of these substances against chemical conditions are quite high. In addition, polyethylene terephthalate, which is colorless and transparent, also has a typical crystallization rate of 50%.
