Silicone Surfactant SiBH-2690

Description

SiBH-2690 foam stabilizer is a Si-C bond, non-hydrolytic type polysiloxane polyether copolymer. This is a versatile foam stabilizer used for the production of polyurethane rigid foam plastic used in appliances and construction industry. It is suitable as general-purpose surfactant for other rigid foam applications and with different blowing agents including iso-, cyclopentane, HCFC-141b and high water content foaming system.

Properties
• Non-ionic silicone surfactant
• Excellent water solubility with any ratio
• Excellent emulsifying and wetting ability

Application

• Suitable for use in systems for refrigeration, lamination and pour-in-place foam applications, using hydrocarbons as blowing agents and co-blown with water
• Provides good solubility of cyclo-pentane and cyclo/iso-pentane mixtures in the typical polyol formulations used in the appliances industry
• Delivers extremely fine celled foams, thus obtaining foams with very good thermal insulation performances
• Stabilization of foam growth in pour-in-place applications, in systems using CH, water and HCFC-141b as blowing agents as well as HFCs.
