Product Description

Rubber Silicon Heat Stabilizer Cerium Oxide Organic Based Stabilizers

 

 

   The addition of certain metal oxides or salts, as well as organic compounds of certain elements, to silicone rubber can greatly improve its thermal air aging performance, with cerium oxide being the most commonly used,. Adding a small amount of spray carbon black can also improve the heat resistance. The effect of these additives can only be demonstrated by performing hot air aging in the temperature range of 250~300 ℃ in the recitation hall.

 

Application

 

It is suitable for silicone stopper heat stabilizers.

【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.
