介绍 | PARALOID BTA-731 is a core-shell general purpose MBS modifier having a poly(butadiene/styrene) core with a polymethyl methacrylate shell. It is designed to 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. It also 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. PARALOID BTA-731 finds utility in a variety of conversion processes typically encountered for Vinyl, including blow molding, calendering, thermoforming, extrusion and injection molding. |
