Features Of DOW Fusabond P353 Toughener

  1. Maleic anhydride-grafted ethylene–propylene copolymer for enhanced interfacial adhesion.

  2. Improves impact resistance and ductility in polyolefin-based composites and blends.

  3. Enables robust bonding between non-polar polyolefins and polar substrates (e.g., fillers, fibers, polar polymers).

  4. Offers excellent melt processability with low viscosity and good thermal stability during extrusion and injection molding.

  5. Compatible with a broad range of polypropylene (PP), polyethylene (PE), and thermoplastic elastomer (TPE) systems.

Typical Applications Of DOW Fusabond P353 Toughener

  1. Automotive interior trim components requiring high impact strength and dimensional stability.

  2. Under-hood parts where chemical resistance and heat aging performance are critical.

  3. Appliance housings combining aesthetic surface quality with structural toughness.

  4. Recycled polyolefin modification to restore mechanical performance in post-consumer applications.

  5. Engineering thermoplastic composites reinforced with mineral fillers or natural fibers.
