Features Of DOW Fusabond C250 Toughener

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

  2. Provides excellent adhesion between non-polar polymers (e.g., PP, PE) and polar substrates such as fillers, fibers, or engineering resins.

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

  4. Delivers consistent performance with low gel content and high molecular weight distribution for uniform dispersion.

  5. Enables formulation flexibility as a masterbatch-compatible additive for tailored toughness modification.

Typical Applications Of DOW Fusabond C250 Toughener

  1. Automotive interior trim components requiring dimensional stability and crash-energy absorption.

  2. Heavy-duty industrial packaging films where puncture resistance and seal integrity are critical.

  3. Fiber-reinforced polypropylene (PP) compounds for structural under-hood applications.

  4. Recycled polyolefin blends seeking improved mechanical performance and compatibility.

  5. Multi-layer coextruded barrier structures incorporating EVOH or PA layers.
