Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. [3] This isomer is also known as Pure MDI.

WebIn general, polyurethane can be used in the temperature range of -62°C to 93°C (-80°F to 200°F). Special formulations can extend polyurethane’s performance reach to as high as 150°C (300°F). High-Temperature Operation We select the optimum polyurethane formulation to ensure dynamic performance at high temperature. WebThermoplastic polyurethanes are elastic and melt-processable. Additives can improve dimensional stability and heat resistance, reduce friction, and increase flame retardancy, fungus resistance, and weatherability. Aromatic TPUs are strong, general-purpose resins that resist attack by microbes, stand up well to chemicals.
