Key factor for the high-quality and efficient processing of polyurethane

Whether rigid or flexible, integral skin, filling or energy-absorbing foam is concerned, Hennecke has the appropriate high-pressure polyurethane mixhead for almost every application that requires mixing based on the impingement injection principle, from standard to specific applications. Variable sizes and injector shapes as well as a comprehensive range of accessories ensure that the mixheads can be adapted to suit a great variety of conceivable requirements - including yours!

Various raw materials and applications make mixing using impingement injection impossible. This is the case, for example, when casting systems or high-viscosity components are used. For many reactive components and additives - e.g., in continuous slabstock lines - mixheads are fitted with special stirrers to ensure that the reactive systems and additives are mixed homogeneously in the mixing chamber and a laminar output is achieved. To a certain extent, processors can influence factors such as the cell structure and cell size of foaming systems by means of particular types of stirrer. High-strength stirrers are used in compact and cellular elastomer systems, ensuring optimal results even when the processing parameters are extremely difficult.
