Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Viscosity (cps) Acid Value mg KOH/gm. Unsaturated polyesters are copolyesters—that is, polyesters prepared from a saturated dicarboxylic acid or its anhydride (usually phthalic anhydride) as well as an unsaturated dicarboxylic acid or anhydride (usually maleic anhydride). It is located on the National Road SS 12 close to the exit Modena-Brennero (A22) and Trieste-Torino (A4) motorway exit. It is often known by its trivial name, polyethylene terephthalate (PET). R10X0 Pure Orthophthalic Resin for Casting. Textile field. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... …the aliphatic group are the unsaturated polyesters, a class of resins that are molded into fibreglass-reinforced structures such as pleasure-boat hulls. Our editors will review what you’ve submitted and determine whether to revise the article. There is a whole range of polyesters made from different acids, glycols and monomers, all having varying properties. Updates? Fiberglass-reinforced unsaturated polyesters find wide application in bodies of yachts and as body parts of cars. Unsaturated polyester resins in styrene as comonomer solvent gels to a thermoset stageby network formation due to free radicals produced by the redox reaction between cobalt octoate (promoter) and methyl ethyl ketone peroxide (MEKP) as initiator. Unsaturated polyester resin is a thermoset, capable of being cured from a liquid or solid state when subject to the right conditions. Institute of Materials Science and Technology (INTEMA), University of Mar del Plata–National Research Council (CONICET), (7600) Mar del Plata–Argentina . The maleic anhydride units of this copolyester are unsaturated because they contain carbon-carbon double bonds that are capable of undergoing further polymerization under the proper conditions. Unsaturated polyester resin (UPE) * was one of the earliest liquid polymers to be rotationally molded. You can define the polyester resin as a polymer obtained by the polycondensation reaction between polyacids and polyalcohols. Appearance. Therefore, we can categorize them as condensation polymers. Polyesters display a wide array of properties and practical applications. tgel indicates commencement of polymer cross-linking (setting) while θpeak controls shrinkage and cracking of polymer. Required fields are marked * Chemical corrosion resistance is good.Unsaturated polyester resin resistance to water, dilute acid, dilute alkali performance is better, poor resistance to organic solvents performance, at the same time, the chemical corrosion resistance of resin with its chemical structure and geometric switch, can … Isophthalic, thixotropic, Non Accelerated, • Used where high performance water and chemical resistant required and suitable for fuel tanks and chemicals storage tanks, Isophthalic, thixotropic, Pre Accelerated, Isophthalic, Thixotropic , Non Accelerated, • Excellent durability & chemical resistance. Chemical nature: Trade Name: Other Names: Product Use: Creation Date: This version issued: Poisons Information Centre: Unsaturated Polyester Resin SYNTHEPOL PE Resin Resin Solution, Flammable. Unsaturated polyester resins are the condensation products of unsaturated acids or anhydrides and diols with/without diacids. • Suitable for boat hulls and also used for top coat of laminate • Coating for water tanks, boat, wall panels, cooling towers etc. Reviews (0) Reviews There are no reviews yet. Polyester, a class of synthetic polymers built up from multiple chemical repeating units linked together by ester (CO-O) groups.
