PARALOID™ BTA-730 is an MBS modifier ideal for high-impact film and sheet applications where transparency is critical. This spherical white powder is free flowing, which allows for dust-free mixing and higher-output production.
Dow PARALOID™ BTA impact modifiers are designed for use in polyvinyl chloride (PVC) film and sheet applications. PARALOID™ BTA-730 is a methacrylate butadiene styrene (MBS) impact modifier that imparts impact resistance, clarity, and crease whitening resistance for general purpose applications. PARALOID™ BTA-730 is recommended for use in transparent PVC applications, such as bottles or containers utilizing blow molding processing.
