Dow ENGAGE 8401 Impact Modifier

ENGAGE™ 8401 is a Dow ethylene-octene copolymer polyolefin elastomer. It delivers high clarity, excellent flow, and compatibility with hot-runner molds. Its low density cuts costs and reduces part weight, providing reliable performance for durable industrial and consumer goods.

Features Of DDow ENGAGE 8401 Impact Modifier

  1. High transparency, suitable for products requiring visual inspection, enhancing appearance recognition and quality control

  2. Excellent flow properties, enabling complex structural injection molding and compatibility with hot-runner molds to improve production efficiency

  3. Low density, effectively reducing raw material and production costs while decreasing end-product weight

  4. High tear strength and elastic recovery, improving product impact resistance and fatigue resistance

  5. Wide temperature tolerance range, maintaining stable mechanical performance between -47°C and 90°C

Typical Applications Of Dow ENGAGE 8401 Impact Modifier

  1. Injection-molded industrial durable components, such as seals, cushions, and equipment housings

  2. Consumer durable goods, including appliance handles, sports equipment parts, and children's toy structural components

  3. Impact modifier for engineering plastics, used to enhance low-temperature toughness of materials like polypropylene (PP)

  4. Automotive interior parts, such as dashboard buffer layers and door seals, balancing flexibility and durability
