Features Of DOW Fusabond PTW Toughener

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

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

  3. Offers superior thermal stability during high-shear compounding and extrusion processing.

  4. Enables consistent performance across a broad range of formulation systems, including talc- and mineral-filled composites.

  5. Designed for low-volatility operation with minimal odor and extractables—supporting automotive interior and food-contact-adjacent applications.

Typical Applications Of DOW Fusabond PTW Toughener

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

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

  3. Appliance housings demanding improved toughness at low temperatures.

  4. Medical device carriers and trays requiring enhanced drop resistance and chemical compatibility.

  5. Recycled polyolefin upcycling formulations to restore mechanical performance.
