Silicone Surfactant

L-626 is a specialty silicone designed specifically viscoelastic foam and low permeability

slab formulations. Its unique cell opening characteristics helps improve processing latitude in tight foam formulations.

◎ L-626 provides a fine and open cell structure, with good processing latitude. ◎ Generally, L-626 is used in conjunction with other surfactants(SC-154/SC-155/L-620). ◎ L-626 can also be used in semi-rigid slab foams for automotive headliner systems to help prevent shrinkage.

Properties	Specification
Form	Slightly Hazy Liquid
Viscosity(25℃, cSt)	14,000
Specific gravity(25℃)	0.92
Flash Point(PMCC, ℃[℉])	88[190]

L-626 can either be premixed with other surfactants or diluted in a polyol

▶Applications

L-626 has found use in the manufacture of high density viscoelastic foams like those used in high-performance bedding. This unique surfactant is of greatest utility when foam having density ≥3.0 pcf is desired.
