The polyester resin used in most molding applications is a viscous liquid requiring the addition of catalysts and accelerators to complete the curing process. It exhibits various physical properties, such as high tensile, binding and impact strength, along with resistance against heat and corrosion. POLYESTER RESINS, are a group of thermosetting synthetic resins, which are poly condensation products of dicarboxylic acids with dihydroxy alcohol’s, used along with Fibre Glass Mats for production of FRP Components which are durable and outstanding in Mechanical, Electrical and Chemical properties. Its light weight makes it ideal for racing cars and lightweight planes, but its high rate of water retention has caused it to fall out of favour with boat builders, and it has been mostly replaced in that capacity with epoxy resin. She is also an authority on sustainable design, having studied, practiced and written extensively on the subject. Typically 8-10% of the output from MEG production is DEG. Shower image by Semfamily from Fotolia.com. Gelcoat or 'Gel Coat' is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite.The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. A short summary of this paper. Moreover, UP resins are broadly classified as DCPD, orthopthalic, isopthalic, and others (consisting of vinyl ester resins and other specialty resins). Prefabricated shower stalls and closet fixtures are often made of a mixture of polyester resin and acrylic, and decorative metal pieces are often gel-coated with a polyester resin-based colourant to match decor. Polyester resin is an unsaturated, thermosetting resin produced by a reaction between several organic acids and polyhydric alcohols. It is most commonly used in the construction of molded reinforced fiber and composite products. These resins are advanced products of saturated acids (such as isophthalic acid and phthalic acid) and unsaturated acids (such as maleic or fumaric acid), condensed with dihydric alcohols. Polyester resin is a thermosetting unsaturated polymer resin, which is formed from the reaction between organic acids and polyhydric alcohols. Unsaturated polyester resins containing long chain fatty acids and styrene as cross-linking agents are easily available in Pakistan. Typical polyols used are glycols such as ethylene glycol; acids used are phthalic acid, isophthalic acid and maleic acid.

Ellis discovered that unsaturated polyester resins made by reacting glycols with maleric anhydride could be cured to insoluble solids simply by adding a peroxide catalyst. They were unlike the unsaturated polyester resins available nowadays. UPR also finds its use in the manufacturing of tanks and pipes in the chemical industries. Polyester resin is commonly used to bond the fibreglass on the inside of many "wet" appliances, including dishwashers and washing machines. The same lightweight strength that has made polyester resin popular in so many other applications also makes it useful for the manufacture of patio furniture. An unsaturated polyester resin (UPR) is a form of thermoset moulding resin that is used for the manufacturing of glass fiber reinforced plastics (FRP). According to a leading report by Transparency Market Research, the global unsaturated polyester resins market is expected to witness rapid growth in the near future due to the high use of UP resins in fiberglass reinforced plastics (FRP), which have extensive applications in the construction industry. Initially, maleic anhydride was allowed to react with propylene glycol for some time before the addition of phthalic anhydride. Currently, most polyester resin manufacturers across the globe use glycols and acids as a raw material. The unsaturation present in this type of polyesters provides a site for subsequent cross-linking [23-24]. Unsaturated polyester is formed by chemical reaction between glycol with di-basic unsaturated acid. Download Free PDF.
