Polystyrene 525 is a crystal polystyrene for both injection molding and cap layer co-extrusion. Injection molding applications such as medical and laboratory parts, tumblers and jewel boxes demonstrate the polymers ability to b e molded with minimal stresses and fast cycles. Utilizing 525 as a cap layer in cups, plates, and other consumer disposables takes advantage of this polymers melt rheology. Information provided by Total Petrochemicals, Inc. |
