Product Details

WynPUF^®XH-1544is a non-hydrolyzabel silicone surfactant which maybe an excellent candidate for use in difficult to stabilize rigid foam formulations. XH-1544 maybe 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.
