Here we are describing all properties of polyester. One is Physical Property and another is chemical property. They when mixed with hardener get activated, as hardener works as a catalyst for chemical reaction called polymerization. The figure below shows the idealised chemical structure of a typical polyester. The chemical formula of an ester takes the form RCO 2 R′, where R is the hydrocarbon parts of the carboxylic acid, and R′ is the alcohol. It finds major uses in the textile and packaging industries. As a thermoplastic, PET is mainly used for the production of films and blow-molded bottles for carbonated … Ethanolamine, hydrazine hydrate, ethylene glycol and a benzophenone derivative were applied to the fabric by padding technique prior to the thermal treatment. PET is spun into fibers for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into photographic film and magnetic recording tape. We measure it by categorizing into two way. Poly(ethylene terephthalate) British Chemists Whinfield and Dickson finally patented PET or PETE (polyethylene terephthalate) in 1941.
