Niax* Silicone L-5348

Reliable, Low-Density Foams

An organosilicone copolymer used in the manufacture of rigid polyurethane and polyisocyanurate foams, Niax silicone L-5348 is an excellent candidate to consider for the stabilization of one-component foam prepolymers. Generally compatible with commercial isocyanates used by the rigid foam industry, it can be used in the building and construction trades, as well as packaging.

More About Niax* Silicone L-5348

An efficient stabilizer with a wide range of compatibility, Niax silicone L-5348 may be a good choice for creating one- and two-component low-density, open-cell foams for pour-in-place applications that use either water or low-boiling hydrocarbon blowing agents. Niax silicone L-5348 may also be adapted for one-component gun foams, as well as canned foams dispensed with a straw adapter. Niax silicone L-5348 is typically compatible (or nonreactive) with other isocyanates used by the rigid foam industry and can extend the shelf life of prepolymers.

Potential applications for Niax silicone L-5348 include:

  • Sprayed or pour-in-place foams in construction
  • Packaging foams
  • One-component foams dispersed in foam guns or with a straw adapter
