Silicone Surfactants

Everchem’s SILSTAB® silicone surfactants are used to stabilize rigid polyurethane foam systems. The selection of the proper silicone stabilizer depends on the chemical formulation (polyols, isocyanates, blowing agents, etc.) of the foam system, the manufacturing process (spray, pour, etc.) and the desired foam properties. Siltech offers a comprehensive range of silicone surfactants for water-blown systems, including both open and closed cell. Siltech also offers novel silicone surfactants for the next generation of blowing agents such as HFC, HFO and hydrocarbons. Typical applications include spray, boardstock, pour-in-place and high-density molded foams.
