Features Of DuPont Fusabond E588 Toughener

  1. Maleic anhydride-grafted ethylene–propylene copolymer designed for enhanced interfacial adhesion in multi-material systems.

  2. Enables improved impact resistance and ductility in polyolefin-based composites without compromising melt processability.

  3. Offers excellent thermal stability during extrusion, injection molding, and rotational molding operations.

  4. Provides superior compatibility with both non-polar polyolefins (e.g., PP, PE) and polar substrates (e.g., glass fibers, talc, nylon).

  5. Low volatility and minimal odor—suitable for demanding automotive and consumer goods applications requiring low VOC emissions.

Typical Applications Of DuPont Fusabond E588 Toughener

  1. Automotive interior trim components requiring high toughness and scratch resistance.

  2. Under-hood parts where dimensional stability and heat resistance are critical.

  3. Multi-layer coextruded films for packaging with enhanced seal integrity and puncture resistance.

  4. Recycled polyolefin blends to restore mechanical performance and broaden end-use suitability.

  5. Engineering thermoplastic composites incorporating mineral or natural fiber fillers.
