Features Of DOW Fusabond E528 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 or fillers.

  3. Offers superior thermal stability for high-temperature extrusion and injection molding processes.

  4. Enables low-addition-level toughening (typically 2–10 wt%) for optimized cost-performance balance.

  5. Compatible with conventional compounding equipment and standard polymer processing conditions.

Typical Applications Of DOW Fusabond E528 Toughener

  1. Automotive interior trim components requiring dimensional stability and impact durability.

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

  3. Appliance housings combining polypropylene with mineral fillers or recycled content.

  4. Medical device trays and containers demanding consistent mechanical performance across sterilization cycles.

  5. Consumer electronics enclosures requiring improved drop resistance and surface aesthetics.
