Dow ENGAGE™ 8411 is an ethylene-octene elastomer designed for durable injection molded industrial and consumer goods and compression molded gaskets. It offers high clarity for products requiring visual inspection and is compatible with hot runner molds to enhance production efficiency. Its low density helps control resin and production costs while reducing end-product weight. Blended with PP and PE, it delivers good impact properties, especially in automotive TPO applications requiring high melt flow modifiers.
High clarity & visual compatibility: High transparency meets the needs of products requiring visual inspection without additional processing.
High flow & hot runner compatibility: Melt index up to 18g/10min enables high-speed injection molding and hot runner compatibility, significantly reducing cycle times.
Low density for cost & weight reduction: Density of only 0.880g/cm³ effectively lowers resin and production costs while lightening end products.
Significant toughening effect: Greatly enhances impact resistance of PP/PE blends, especially in high melt flow modification scenarios.
Versatile processing: Supports injection and compression molding for elastic components like gaskets.
Strong compliance: Meets EU 10/2011 and U.S. FDA FCN 424 food contact standards.
Automotive TPO products: Bumpers and exterior panels, improving low-temperature crash resistance and clarity.
Injection molded durable goods: Industrial parts and consumer durables such as transparent containers and tool housings.
Compression molded gaskets: High-clarity sealing gaskets for equipment requiring visual inspection.
Thin-wall injection parts: Suitable for thin-wall products, ensuring strength and processing efficiency.
Food contact products: Food machinery seals and kitchen elastic components, meeting safety and compliance requirements.
