|---|
| JPHIPSE is a high impact polystyrene with an excellent balance of flow, toughness, stiffness and heat resistance as compared to other HIPS resins. It is appropriate for extrusion applications where stiffness and toughness combined with trimmability are important. JPHIPSE is also commonly used for deep draw thermoforming and injection molding. A major use of this product is in appliances and housewares as well as food packaging and disposables applications such as cups, lids and serviceware.&& |
