| G.E. Noryl® S.E.1X-780 Polyphenylene Ether High Impact Polystyrene/ Synthetic Thermoplastic Polymer | ||
| Noryl® engineering thermoplastic resin is based on Polyphenylene Ether (PPE). PPE, a high-heat amorphous polymer, forms a miscible, single-phase blend with polystyrene. General characteristics include high heat resistance, good impact strength, stiffness, flame retardency, excellent electrical properties, hydrolytic stability, dimensionally stability, and very low creep behavior at elevated temperatures. Noryl® color is grey. | ||
