Styrene-based terpolymers increase high heat performance

Polyscope Polymers : 12 June, 2013  (New Product)
Polyscope, the producer of styrene maleic anhydride (SMA) copolymers, has added a third dimension to its portfolio by manufacturing terpolymers consisting of styrene, maleic anhydride and N-phenylmaleimide. These new products are commercialised and branded as Xiran IZ grades. Compared to similar materials on the market, the grades are claimed to deliver higher heat performance and by having very low volatile residual levels. This is especially relevant for styrenics like ABS. Furthermore, the processablity of the final product is very likely to improve and the price and performance is attractive.

Two new grades, Xiran IZ1018M and Xiran IZ0721M are designed to increase the high heat performance of many engineering plastics. They were developed to respond to the increasing trend within the plastic industry to create styrenic engineering plastics with high temperature resistance and low volatile residuals. The new Xiran IZ grades exhibit a glass transition temperature (Tg) of 175C or higher and can be exposed to higher processing temperatures with excellent miscibility in styrenic polymers like ABS.

Xiran IZ1018M and Xiran IZ0721M have a different ratio of styrene, maleic anhydride and N-phenylmaleimide.

In order to produce these products Polyscope has upgraded its continuous polymerisation process in Geleen, The Netherlands, enabling an exceptional terpolymer with a high thermal stability and excellent adhesion properties due to the presence of the maleic anhydride groups to be manufactured with the optimum balance of thermal improvement, mechanical properties and cost performance.
