Silicone Foam Stabilizer RJ-F1800

※MSDS Download ※TDS Download Inquiry


Silicon Stabilizer RJ-F1800 is a non-hydrolyzable silicone, designed to provide excellent foam stability and fine regular cell structure in extremely low density foams using liquid carbon dioxide as the blowing agent. In stretched formulations with high TDI, high water, high CO2, Silicone RJ-F1800 provides superior nucleating efficiency and dramatically reduces striations in the foam bun. It has full hydrolytic stability and can be used as a separate stream or in water/amine/ silicone preblends. Silicone RJ-F1800 offers enhanced stability while yielding foams with good breathability.
