More About Niax* Silicone L-620

Niax silicone L-620 typically offers several key benefits for the production of conventional flexible slabstock foams. It can provide superior processing of low-combustibility, all-water foams, as well as methylene chloride blown filled and sponge foams. For formulations with reduced blowing agents using Geolite* modifiers, it generally offers maximum stability. Plus, the agent can provide formulations over a wide range of silicone and tin catalyst levels, for an excellent breathability profile.

A highly efficient silicone, Niax silicone L-620 can create foams with narrow density and IFD gradients, as demonstrated by both bench and full-scale machine trials for a broad range of flexible urethane slabstock formulations.

Potential applications for Niax silicone L-620 include: 

  • The full range of flexible polyether slabstock foams
  • Low-combustibility foams
