Product Details

 WynPUF® XH-1544 is 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.

Physical Data

● 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.

Levels of Use (additive as supplied)

1.5% is recommended for preparing polyurethane rigid foam. Use levels for this type of foam can vary from 1.5 to 2.5 parts per 100 parts polyols.

Package and storage stability

Available in 200kg drums.

24 months in closed containers.
