Inorganic fillers have attracted a great deal of interest as reinforcing materials for fireproof performance in silicone rubber (SR). In this study, magnesium hydroxide (MDH) and aluminium hydroxide (ATH)/SR composites, well known fireproof materials, and mineral wool/SR composites were analyzed for thermal and physical properties. It was confirmed that mineral wool/SR composites have an improved fireproof performance than the (MDH, ATH)/SR composites through gas torch flame test, cone calorimeter, and thermogravimetric analysis (TGA). MDH/SR shows great tensile, tear strength and elongation at break through SEM and UTM due to the fine dispersion of MDH in SR. Also, mineral wool/SR composites show compressive strength and hardness properties higher than those of (MDH, ATH)/SR composites.
