Industrial Silicone Rubber Cerium Oxide Heat Stabilizer Heat Stabilizer Cerium oxide can prevent free radical reactions caused by oxidation in silicone rubber within a certain temperature range and regenerate under the influence of atmospheric oxygen. By absorbing trace amounts of acidic or alkaline substances in silicone rubber that catalyze degradation reactions, it provides thermal stabilization to the material. 【Application】 It is suitable for Silicone heat stabilizers.
