Polyscope expands portfolio with XERAN® compatibilizers

Polyscope has broadened its portfolio of XIRAN® neat resins, compounds, powders and liquids with a range of XERAN® compatibilizers. The maleic anhydride functionality in these XERAN copolymers and terpolymers makes them extremely suitable as a compatibilizer and coupling agent in many applications.

Polyscope is constantly researching new opportunities for its specialized maleic anhydride functionalized copolymers and terpolymers. The XERAN portfolio opens a window to new polymer systems that need compatibilization, as XERAN improves the adhesion between two polymers which are normally immiscible. Additionally it optimizes the interfacial tension and offers stabilization of the morphology against high stresses during conversion. The compatibilization results in a significant improvement of the mechanical properties, predominantly impact performance. The styrene based XERAN polymers are highly suitable for compatibilizing styrene based engineering plastics.

Different immiscible polymeric systems need different compatibilizers. The new XERAN portfolio consists of polymers with varying molar mass and varying maleic anhydride functionality. Polyscope has developed XERAN grades that compatibilize compounds of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) or acrylonitrile styrene acrylate (ASA), compounds of polyamide (PA) and ABS and compounds of polybutylene terephthalate (PBT) and ABS or ASA. The technical and commercial benefits are clear in these systems and it is expected that XERAN will demonstrate its capabilities in many more polymeric engineering compounds in the near future. Polyscope even offers a XERAN coupling agent to enhance performance of styrene acrylonitrile (SAN) with glass fibres.

Peter Tackx, Business Director Engineering Plastics at Polyscope Polymers explains: “Polyscope has a customer driven mindset to continuously develop new materials for new applications to enhance plastic performance in the global engineering plastics industry. 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 polymerization asset creates added value”.

About Polyscope
Polyscope is the global leader in research, product development, production and supply of styrene maleic anhydride (SMA) copolymers, compounds, aqueous solutions and styrene, maleic anhydride and N-phenylmaleimide (SMANPMI) terpolymers. Polyscope offers a full spectrum of styrene maleic anhydride copolymers and compounds for engineering plastic and specialty chemical applications under the trade name XIRAN®. The XIRAN® resins have a very broad molar mass range and a broad maleic anhydride variation. For engineering plastics the SMA/ABS based compounds have varying impact modification levels and glass fiber content. For specialty chemical applications Polyscope offers low molecular weight XIRAN® base resins and solutions that are chemically modified to meet customer needs.

A global customer base is supported from corporate headquarters and production in Geleen, The Netherlands, and with local compounding and contact manufacturing facilities, as well as sales & marketing support in Europe, North America, and Asia.
