New high temperature blowing agents

With the Tracel G 6800 series of blowing agents for TPEs Tramaco has developed a new solution to overcome a well-known problem: Encapsulated physical blowing agents (so-called microspheres) for injection moulding and extrusion of TPEs are often limited to relatively low processing temperatures. The new series opens up a much wider range of applications as the products enable processing temperatures even above 200 °C.

The Tracel G 6800 series is a joint development by Tramaco and Müller Kunststoffe. Initial tests with both soft and hard TPEs show that the G 6800 products greatly improve the surface quality and foam structure compared to conventional chemical blowing agents, said the companies. The products are in granular form and are therefore very easy to dose and dust-free in operation.

The Rowa group will inform about these and other new products at the Fakuma. hall B1, stand 1215
