Applying its extensive expertise in polyurethane technology, Covestro has developed a broad portfolio of Desmodur® systems specifically for Rotational Casting of industrial rollers with a wide range of hardness values suitable for paper and steel mill rollers.
This range contains cast polyurethane systems designed for Rotational Casting available in ether and ester. Because the components are processed at high temperatures, dedicated equipment is required. Rotational Casting molding technique enables the coating of rollers with liquid polyurethane without a mold.
