Name: DuPont Fusabond N525 Toughener
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of DuPont Fusabond N525 Toughener

Maleic anhydride-grafted ethylene-propylene copolymer offering excellent compatibility with polyolefins and engineering thermoplastics.
Enhances impact strength and ductility without significantly compromising stiffness or heat resistance.
Provides superior interfacial adhesion in multi-material systems, including PP/PA, PP/PC, and TPO composites.
Thermally stable up to 280 °C, supporting high-temperature processing such as injection molding and extrusion.
Low extractables profile, suitable for applications requiring regulatory compliance (e.g., FDA-compliant formulations).

Typical Applications Of DuPont Fusabond N525 Toughener

Automotive interior and exterior trim components requiring dimensional stability and low-temperature impact performance.
Toughened polypropylene (PP) compounds for under-hood parts exposed to thermal cycling and mechanical stress.
Multi-layer coextruded films and laminates where adhesion between dissimilar polymers is critical.
Recycled PP and PE blends, improving mechanical consistency and enabling higher post-consumer content utilization.
Engineering plastic alloys such as PP/PA6 and PP/PC blends used in durable consumer electronics housings.
