"Research progress in flame retardancy and smoke suppression of silicone rubber foam"

Abstract

The flame retardancy and smoke suppression performance of silicone rubber foam (SiFs) greatly affected its promotion and application in the field of high performance materials. Improving the flame retardancy and smoke suppression performance of SiFs had became a hot and difficult topic in recent years. The current research status of flame retardancy and smoke suppression of SiFs in flame retardant systems such as metal hydroxide flame retardants, boron- based flame retardants, phosphorus-and nitrogen-based flame retardants, platinum catalysts, microcapsule flame retardants, and ceramic-based flame retardants had been summarized with 67 references. Besides, the corresponding flame retardancy mechanisms had been expounded. Finally, the future research direction of flame retardancy and smoke suppression of SiFs was presented.
