PARALOID™ BTA-733ER

Core-shell general purpose MBS modifier. Having a poly (butadiene/ styrene) core with a polymethyl methacrylate shell. It is designed to help improve the impact performance of transparent vinyl containers, either blow molded or thermoformed. It is a particularly efficient impact modifier at low temperatures because of the low glass transition temperature of the rubber core. Provides good chemical resistance and deters water blush. Because of the core-shell structure, the improvement in impact performance is obtained with only minor effect on other mechanical properties such as modulus and heat distortion temperature. Finds utility in a variety of conversion processes typically encountered for vinyl, including blow molding, calendering, thermoforming, extrusion and injection molding. Used for semi-rigid and rigid vinyl plastics for food packaging as well as for food-contact applications, blow molded containers (bottles/jars), calendered sheet (blister pack applications), extruded sheet (transparent signs), injection molded clear fittings.
