FUSABOND® is Dow’s line of functional grafted polymers used as compatibilizers or coupling agents in polyolefins and engineering plastics. With PE or PP backbones grafted with functional groups such as MAH, they improve compatibility and adhesion with polar materials. They are widely applied in wood–plastic composites (WPC) and wire & cable (W&C). The products are produced from ethylene–acrylic acid copolymers modified through MAH grafting.

FUSABOND® M603

Features

• PP-based resin grafted with maleic anhydride (MAH)

• Designed for GF-reinforced PP and PP/PA, PP/PET blend systems

• Significantly improves interfacial adhesion, enhancing bonding between GF and PP

• Improves impact strength, tensile strength, and heat resistance of composites

• Ensures stable processing and good dimensional stability

Applications

• Automotive parts: bumpers, interior components, under-the-hood parts

• Glass-fiber–reinforced PP: improved strength, heat resistance, and durability

• PP/PA and PP/PET blends: enhanced compatibility and mechanical properties

• Industrial components and appliance housings requiring high rigidity and heat resistance
