HYRENE^®

Entec Polymers offers an array of both branded prime and generic prime options in our commodity polymer portfolio. Our HYRENE® branded Polystyrene is an excellent option for customers seeking top level quality in either the GPPS or HIPS markets.

GPPS is most commonly used in applications requiring high levels of clarity and surface gloss or single use food packaging. The mechanical properties of GPPS allow it to be used in a variety of applications. Our HYRENE® GPPS products range from 1-18 melt flow which allows your design and manufacturing team to find an optimized balance between processing and mechanical properties. Styrenic Polymers have an extremely forgiving process window which can help with increased throughput and reduced scrap rate.

ADVANTAGES OF GPPS:
