Niax* Silicone L-6895


Niax silicone L-6895 is an excellent surfactant to consider for use in production of insulation foams for refrigerators and other cool-store applications. Typically providing good pentane solubility, low thermal conductivity and low void formation, Niax silicone L-6895 may enable high use levels of pentane in formulation. This can, in turn, provide extremely fine cells, which promotes low thermal conductivity.


More About Niax* Silicone L-6895

The typical use level of Niax silicone L-6895 is two to three parts per hundred of polyol (php). Niax silicone L-6895 enables switching from c-pentane to less soluble grades like iso- or n-pentane - generally without any haziness or phase separation problems. Niax silicone L-6895 typically demonstrates low thermal conductivity with cyclopentane, along with a mixture of cyclopentane and other hydrocarbons. 

Niax silicone L-6895 promotes superior foam flow and even density distribution. It can significantly reduce void formation, which is particularly evident at the foam surface and end-flowing foams sections. The combined effect on fine cells and void reduction can help deliver foam with low thermal conductivity in the whole foamed cabinet, which may improve overall energy savings. 

Potential applications for Niax silicone L-6895 include foam production for:

  • Refrigerators
  • Other cold-store applications
  • Water heaters
  • Pipe insulation
