Silicone surfactant SiBH-2644

Description

SiBH-2644 is a non-hydrolyzable silicone surfactant rigid foam formulations. It is an effective stabilizer for rigid foam formulations incorporating reduced levels of auxiliary blowing agent, for example, high-water/reduced-CFC systems. The foams contained a narrow distribution of small, fine, closed cells that contribute to excellent k-factor performance. It may also be suitable for HCFC-141b systems with excellent dimensional stability and compressive strength.

Application

• Effective for stabilization of high water-reduced HCFC rigid foam formulations
• Provides excellent compressive strength and dimensional stability in reduced-HCFC systems
• Imparts chemical stability and compatibility in slow reacting rigid foam systems
• Maximizes HCFC retention by preventing cell coalescence
• Produces fine, uniform cell structures with a high degree of closed cells
