More About Niax* Silicone L-500

Niax silicone L-500 can also be used in High Resilience/Combustion Modified High Resilience foam as a co-stabilizer to generally increase block stability and improve top to bottom density gradient. Niax silicone L-500 may also reduce the so called "cold-flow" phenomenon typically observed in medium- to high-density HR/CMHR foams.

Potential applications for Niax silicone L-500 polyurethane include:

  • High-resilience foam used in the manufacture of furniture and bedding
  • Viscoelastic MDI-based polyurethane foams
