Polyester (PET) is an organic material, a polymer plastic that is commonly used as a fiber for cloth production, or a matrix for glass fibers in Fiberglass
In situ Production
Polyesters are polymers (chains) that contain ester groups in their repeating structure. The most common form is polyethylene terephthalate (PET). Polyethylene terephthalate is produced from ethylene glycol and dimethyl terephthalate (DMT) (C6H4(CO2CH3)2) or terephthalic acid.
