CAS:Ethylene terephthalate (ET) is a polymer that is used in the textile industry. ET is made by the reaction of ethylene glycol with terephthalic acid, which results in the formation of linear polyesters. This process can be done as a batch or continuous process. The polymerization process starts by heating the reactants and then adding an appropriate catalyst to initiate the reaction. This step is called “extrusion” and it involves forcing the reactants through a small hole under high pressure, which creates long strings of molecules of polyester. After this, the polymer strands are heated to remove any remaining water and are stretched out into long fibers under tension. These fibers are then drawn to make them thinner and stronger before they are cut into lengths. Finally, they are wound onto spools for later use.Formula:C40H16D16O16Purity:Min. 95%Molecular weight:784.77 g/molAlverine EP Impurity D
