Dow Engage 8400 Impact modifier

Dow ENGAGE™ 8400 is a pelletized ethylene-octene copolymer with high flowability and clarity, compatible with hot runner molds to boost production efficiency. Its low density helps control resin and production costs while reducing end-product weight. Blended with PP and PE, it delivers excellent impact properties, making it ideal for durable injection molded goods and impact modification.

Features Of Dow Engage 8400 Impact modifier

  1. High clarity, suitable for products requiring visual inspection without additional processing.

  2. Excellent flow properties, compatible with hot runner molds to shorten cycle times and improve productivity.

  3. Low density for cost and weight reduction, cutting material and production costs while lightening end products.

  4. Significant toughening effect, greatly enhancing impact resistance of PP/PE blends, especially in high melt flow modification scenarios.

  5. Versatile processing, supporting injection and compression molding for elastic components like gaskets.

Typical Applications Of Dow Engage 8400 Impact modifier

  1. Injection molded durable goods: Industrial parts and consumer durables such as transparent containers and tool housings.

  2. PP/PE impact modification: Enhancing impact resistance and low-temperature toughness of appliance housings and automotive trim.

  3. Compression molded gaskets: High-clarity sealing gaskets for equipment requiring visual inspection.

  4. Thin-wall injection parts: Suitable for thin-wall products, ensuring strength and processing efficiency.
