Polyols can also be used in non-urethane applications such as surfactants and oil demulsifiers. One NOP producer, Cargill, estimates that its BiOH (TM)polyol manufacturing process produces 36% less global warming emissions (carbon dioxide), a 61% reduction in non-renewable energy use (burning fossil fuels), and a 23% reduction in the total energy demand, all relative to polyols produced from petrochemicals. lt is the base component of polyurethane, a polymer used by various industries including the construction, insulation, furniture manufacturing, automotive and textile industries. The polymerization catalyst is a Lewis . Polyesters are a class of polymers that allows for enormous variation of structural and property design. As polyurethanes are made from the reaction between an isocyanate and a polyol, the section is divided into three parts: a) production of isocyanates b) production of polyols c) production of polyurethanes (a) Production of isocyanates Although many aromatic and aliphatic polyisocyanates exist, two are of particular industrial importance. Open cast molding also starts in a liquid form, but it goes into an open mold which needs heat from a special oven to finish it off. 9 Marketing Channel, Distributors and Customers. First, a starter (polyols are most often used) is treated with KOH in a reaction vessel and is converted to the corresponding alkoxide, the actual active species, after removing the water that is.
