WynPUF® XH-1544 is a non-hydrolyzable silicone surfactant which may be an excellent candidate for use in difficult-to stabilize rigid foam formulations.
XH-1544 may be 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.
Viscosity at 25℃：400-800 CS
