Polyscope Polymers (Geleen / The Netherlands; www.polyscope.eu) has added a range of “Xeran” compatibilisers to its portfolio. The company said Xeran opens a window to new polymer systems that need to be made compatible as it improves the adhesion between two polymers which are normally immiscible. This compatibilisation results in a significant improvement of mechanical properties, mainly impact performance, said Polyscope. Xeran also optimises interfacial tension and stabilises morphology against high stresses during conversion.

Polyscope explained that different immiscible polymeric systems need different compatibilisers. As such, the “Xeran” portfolio comprises polymers with varying molar mass and maleic anhydride (MA) functionality, as well as styrene-based grades that are highly suitable for compatibilising engineering plastics containing styrene. Grades have been developed to make compatible compounds of PC and ABS or ASA; PA and ABS compounds, as well as those of PBT and ABS or ASA. A Xeran coupling agent is also offered to enhance performance of SAN with glass fibres. The company said it expects to demonstrate Xeran’s capabilities in many more polymeric engineering compounds in the near future.

Peter Tackx, business director, engineering plastics at Polyscope Polymers, commented: “The Xeran product line is the result of close co-operation with our customers wherever we see that product innovation and the uniqueness of our polymerisation asset creates added value.”
