More polymers take the heat

More polymers take the heat

Polyscope is expanding its XIRAN® heat booster range. Originally introduced to increase the high temperature resistance of acrylonitrile butadiene styrene (ABS) and acrylonitrile styrene acrylate (ASA), XIRAN® heat boosters are now also proving succesful in increasing the heat performance of other styrenic polymers, such as polystyrene (PS) and styrene acrylonitrile (SAN), as well as polymethylmethacrylate (PMMA). The extensive XIRAN® heat booster range has positioned Polyscope as the pioneer for heat perfomance promotion of engineering plastics.

Leading Position in ABS and ASA
Polyscope has build a leading position at large global ABS and ASA polymer producers and compounders since the introduction in 2013 of a special XIRAN® grade with high efficiency (XIRAN® IZ). The XIRAN® IZ-grades, which are terpolymers based on styrene, maleic anhydride and a third monomer, N-phenylmaleimide, are an efficient solution for improving the thermal performance, with very low levels of residual volatiles and easy processability at standard processing conditions. The compounds based on XIRAN® IZ are used in automotive applications, consumer products and appliances where increased heat resistance is required.

Extensive Heat Booster Range
Building on the current success, Polyscope recently added a new grade, which boosts heat resistance even further. The new grade has a glass transition temperature (Tg) of 198oC and can be exposed to high processing temperatures with excellent miscibility in styrenic polymers.
Building even further, the benefits of XIRAN® heat booster additives are now also proving succesful in increasing the heat performance of other styrenic polymers, such as PS and SAN, as well as PMMA. An example is high-impact polystyrene with an increased heat resistance for microwaveable food packaging.

Ferdi Faas, Business Unit Director Engineering Plastics at Polyscope Polymers B.V. says: 

‘Polyscope and its customers are continuously exploring new opportunities and applications for XIRAN® in combination with other polymers. Since Polyscope was founded ten years ago, our ability to transfer Fresh thinking into Great products, our efficient organisation, and management with global ambitions have made Polyscope into a multiple award winner in the engineering plastic and specialty chemical markets.’
