Thermoset processing

Creating cross-linked polymers

Due to their reactive processing, thermoset materials require specialized manufacturing technology. This begins with the mixing of the initial formulation and extends to the cross-linking or shaping and post-treatment. We have a wide range of modern equipment at our disposal to handle a variety of thermoset moulding compounds and materials safely and efficiently. These include epoxy resins, polyurethanes, polyesters, acrylates, and many more. The focus is particularly on the production of fibre composites with thermoset matrix systems.
