• Influencing the characteristics of raw material systems

Additive processing

Metered addition of liquids and processing of solids

The properties of polyurethane systems can be significantly improved by a wide variety of liquid and solid additives. While raw materials are prepared in a batch process, sometimes liquid additives such as flame retardants have to be metered into the mixhead directly online, or into the flow of one of the main components. Higher flammability ratings for polyurethane products can be achieved when solid flame retardants such as melamine or ammonium polyphosphate are added. High strength is attained by the addition of short glass or mineral fibers. Heavy substances such as barium sulphate can impart excellent acoustic qualities. Regardless of your choice of additive, Hennecke will supply you with customized mixing equipment that is tailor-made to process any filler used as economically as possible.
