Features Of DOW Fusabond E588 Toughener

  1. Enhances impact resistance and ductility in polyolefin-based compounds without compromising melt processability.

  2. Provides excellent adhesion promotion between non-polar polymers (e.g., PP, PE) and polar substrates or fillers.

  3. Offers superior compatibility with polypropylene homopolymers and copolymers, enabling uniform dispersion at low loadings.

  4. Delivers improved stress cracking resistance in demanding structural and automotive applications.

  5. Features controlled maleic anhydride grafting level for balanced reactivity and thermal stability during processing.

Typical Applications Of DOW Fusabond E588 Toughener

  1. Automotive interior trim components requiring high impact performance and paint adhesion.

  2. Under-hood parts exposed to elevated temperatures and mechanical stress.

  3. Toughened polypropylene compounds for industrial containers and material handling equipment.

  4. Multi-layer coextruded films where interlayer adhesion between PP and EVOH or PA is critical.

  5. Recycled polyolefin blends needing consistent toughness and phase compatibility enhancement.
