Silicone Heat Stabilizer Cerium Oxide Stabilizers thermal management

Cerium oxide can reduce the content of prothrombin, inactivate it.The oxidation aging mechanism of silicone rubber is mainly caused by the oxidation reaction of side chains caused by free radicals. If this chain reaction is prevented, the oxidation process will stop. The composite metal oxide prepared by liquid-phase co precipitation method can significantly improve the heat resistance of silicone rubber. Research has shown that cerium oxide is more effective in improving the heat resistance of silicone rubber. This is because the crystal structure of the prepared composite metal oxide has changed, and their respective antioxidant effects have a synergistic effect. It can inhibit oxidation and improve the heat resistance of silicone rubber.

【Application】

It is suitable for silicone stopper heat stabilizers.

【Specification】

1. chemical properties: TREO>99%

2. Color:light yellow

3.PSD: D50=06-1.0 um

【Product features】

(1) CeO₂ has good oxygen storage through controlling the surface activity of CeO₂, thus restrain the oxidation of side chain.

(2) CeO₂ and silicone rubber has good compatibility which is helpful for them mixing fully, through controlling the size and surface characteristics of CeO₂.

【Application methods】

The addition of ceria into silicone rubber can prevent the side chain from oxidative crosslinking and main chain cyclization degradation. In a certain temperature range, it can prevent the free radical reaction produced by oxidation in the silicone rubber, and can regenerate under the action of oxygen in the air; by absorbing some trace acid or alkaline substances which can catalyze the degradation reaction in the silicone rubber, it plays a thermal stability role on the silicone rubber. At the same time, the special electronic structure (f electron layer is not filled) of ceria makes it easy to form complex. The complex can inhibit the swelling of rubber in solvent by preventing the movement of rubber molecules, thus improving the oil resistance of rubber.
