Dow ENGAGE™ 11547 Polyolefin
Categories:	Polymer; Thermoplastic; Polyolefin
Material Notes:	Product Description: ENGAGE™ 11547 is a Polyolefin Elastomer offering very high flow and excellent rubber loading efficiency as superior impact modifier in thermoplastic polyolefin (TPO) compounds. Its improved toughening capability compared to other commercially available polyolefin elastomers allows for greater ease in optimizing elastomer levels to meet impact resistance requirements in global automotive specifications. TPO formulations containing ENGAGE™ 11547 combine very good processing behavior with very excellent stiffness/toughness balance for automotive parts, such as bumper fascia. The designed to ENGAGE™ 11547 polyolefin elastomer enables shorter injection molding cycle time for the TPO compound. Its designed characteristics contribute to morphology control and improved temperature resistance for final parts. Main Characteristics: High rubber loading efficiency for optimum cost/performance balance Improved toughens for better stiffness/toughness balance Very good flow characteristics High crystallization temperature for short cycle time High melting point for improved temperature resistance Pellet form with partitioning agent for ease of handling Applications: Impact modification of TPO Injection molded polyolefin compounds Availability: Asia Pacific; Europe; Latin America; North America Additive: Antiblock: No; Processing Aid: No; Slip: No Agency Ratings: EU No 10/2011; FDA FCN 424 Form: Pellets Information provided by The Dow Chemical Company
