Spray schiuma

Tensioattivo in silicone per schiuma spray xh - 1544

Silicone surfactant for Spray foam XH-1544

Breve descrizione:

WynPUF® is our brand of silicone regulator for PU. Silicone foam control selection is important when developing open-cell and closed-cell spray systems. XH-1544 help to create the performance advantages you need. Silicone surfactant for spray foam is used in a variety of applications, from basement and attic insulation to acoustic insulation and soundproofing. It is also used to fill gaps in walls and ceiling, providing a tight seal to prevent air and moisture from entering the structure. Spray foam can be used to protect pipes from freezing during cold weather.

XH-1544 is equal to L-6950, B-8518 in international markets.

Dettagli del prodotto

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.
