Features Of DOW Fusabond N416 Toughener

  1. Enhances impact resistance and ductility in polyolefin-based composites without compromising melt processability.

  2. Provides excellent adhesion promotion between non-polar polymers (e.g., PP, PE) and polar substrates (e.g., fillers, fibers, pigments).

  3. Offers superior thermal stability during extrusion and injection molding processing up to 280 °C.

  4. Delivers consistent performance across a wide range of shear rates and processing conditions.

  5. Enables formulation flexibility with low loading levels (typically 1–5 wt%) for cost-effective toughening.

Typical Applications Of DOW Fusabond N416 Toughener

  1. Automotive interior and exterior components requiring dimensional stability and low-temperature toughness.

  2. Industrial packaging films where puncture resistance and seal integrity are critical.

  3. Electrical and electronic housings demanding high impact strength and flame-retardant compatibility.

  4. Consumer appliance parts exposed to mechanical stress and thermal cycling.

  5. Recycled polyolefin blends needing improved interfacial adhesion and mechanical property retention.
