Product Description

Cerium hydroxide silicone rubber heat stabilizer RT-CE-2



  Cerium oxide can reduce the content of prothrombin, inactivate it, inhibit the production of thromboplastin, precipitate fibrinogen and catalyze the decomposition of phosphate compounds. The toxicity of rare earth elements decreases with the increase of atomic weight.
Inhalation of cerium dust, occupational pneumoconiosis, its chloride damage to the skin, can stimulate the mucous membrane of the eye.



It is suitable for silicone rubberto  improve its heat resistance and oil resistance.

【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.
