Grade 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 polymer's ability to be molded witr minimal stresses and fast cycles. Utilizing 525 as a cap layer in cups, plates and other consumer disposables takes advantage of this polymer's melt theology.
