Features Of DOW Elvaloy 741 Toughener

  1. Enhanced impact resistance and ductility in rigid thermoplastic matrices, especially PVC and CPVC compounds.

  2. Excellent low-temperature toughness retention without compromising stiffness or heat deflection temperature.

  3. Good compatibility with polar polymers and ease of incorporation via standard melt-blending equipment.

  4. Improved notch sensitivity performance in extruded and injection-molded profiles.

  5. Halogen-free formulation supporting regulatory compliance for building and infrastructure applications.

Typical Applications Of DOW Elvaloy 741 Toughener

  1. PVC-based window profiles and door systems requiring high impact durability.

  2. CPVC piping and fittings for hot-and-cold water distribution systems.

  3. Rigid packaging sheets where puncture resistance and drop performance are critical.

  4. Electrical conduit and raceway systems demanding UL94 V-0 rated flame-retardant formulations.

  5. Automotive under-hood components requiring dimensional stability and thermal cycling resistance.
