DOW FUSABOND® Functional Polymer
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 MAH, they enhance compatibility and adhesion with polar materials. They are widely used to improve the performance of wood–plastic composites (WPC) and wire & cable (W&C). The products are produced from ethylene–acrylic acid copolymers modified with MAH grafting technology.
Features
PE-based polyolefin grafted with maleic anhydride (MAH)
Designed for flame-retardant filled systems; excellent compatibility with MDH, ATH, CaCO₃, and other inorganic fillers
Maintains good dispersion and processing flow even at high filler loadings
Enhances mechanical properties, flexibility, and flame-retardant performance
Applications
Wire & cable (W&C): compatibilizer and coupling agent for halogen-free FR compounds
High-filler flame-retardant composites
Industrial sheathing and piping materials
