※MSDS Download ※TDS Download Inquiry


Silicone Stabilizer RJ-F1803 a medium-high potency silicone for use in the production of flexible slabstock foam. It is a high performance stabilizer that can help promote well-balanced processing and yield good foam breathability, fine regular cell and exceptional density distribution. RJ-F1803 typically demonstrates broad process latitude in all grades of conventional flexible foam including those with low density where a high loading of auxiliary blowing agents is used. It can also provide good stability for the slabstock foam using a liquid CO2 processs.
