Dow ENGAGE 7447 Impact modifier

Dow ENGAGE™ 7447 is a high melt flow, low density ethylene-butene copolymer designed for use alone or in combination with other elastomers to provide tailored solutions in polymer modification applications. Supplied in pellet form with a talc-dusted surface, it offers excellent processability and complies with food contact safety standards.

Features Of Dow ENGAGE 7447 Impact modifier

  1. High melt flow & low density: Excellent flow properties for high-speed processing, while reducing product weight and cost.

  2. Superior processability: Pellet form blends easily with other polymers; talc-dusted surface reduces blocking and improves production efficiency.

  3. Flexible formulation: Can be used alone or blended with other elastomers to create customized modification systems.

  4. Excellent low-temperature resistance: Glass transition temperature as low as -53.0℃, maintaining elasticity in extreme cold.

  5. Strong compliance: Meets EU 10/2011 and U.S. FDA FCN 368 food contact standards.

Typical Applications Of Dow ENGAGE 7447 Impact modifier

  1. Polymer modification: As a toughener for PP/PE, improving impact resistance and processability of appliance housings and automotive trim.

  2. Elastomer blending: Combined with other POE/OBC materials to create functional compounds with customized hardness and elasticity.

  3. Soft elastic components: Seals and cushions, balancing flexibility and processing efficiency.

  4. Food contact products: Food packaging films and kitchen elastic parts, meeting safety and compliance requirements.
