Niax* Silicone L-580

Excellent Stability

As a nonhydrolyzable silicone, Niax silicone L-580 typically offers excellent foam stability in extremely low-density foams that use liquid carbon dioxide as the blowing agent. It is also designed to provide fine regular cell structure, which yields foams with good breathability.

More About Niax* Silicone L-580

Niax silicone L-580 can provide superior nucleating efficiency and can reduce striations in the foam bun when used in stretched formulations with high toluenediisocyanate, high water and high CO 2 . It also has full hydrolytic stability and can be used as a separate stream or in water/amine/silicone preblends.

This additive generally works well on most commercially available CO 2 equipment, including Cannon's CarDio machine, Beamech's CO-2 machine and Hennecke's NOVAFLEX machine. In fact, most foams poured using Niax silicone L-580 on CO 2 pilot scale equipment of the aforementioned brands achieved a finer, more uniform cell structure than the competitive product, and good density distribution as well

Potential applications for Niax silicone L-580 include: 

  • Extremely low-density foams that use liquid carbon dioxide as the blowing agent
  • Furniture
  • Bedding
