Industrial Grade Organic Silicon Additives Cerium Oxide

     Silicone rubber is prone to oxidation of side groups in high-temperature aerobic environments, forming alkyl radicals. The coupling reaction of free radicals can lead to an increase in crosslinking density, causing the product to become harder and crack. Cerium oxide can prevent oxidation crosslinking of polysiloxane side chains and prevent free radical reactions caused by oxidation in silicone rubber.

 1 Q: How does cerium oxide stabilize silicone rubber against thermal degradation?

A:Cerium oxide functions primarily through its reversible Ce³⁺/Ce⁴⁺ redox cycling, which enables continuous radical scavenging during thermal oxidation

2 Q: Does cerium oxide affect the transparency or color of silicone rubber?

A:Cerium oxide can affect transparency depending on particle size, loading level, and dispersion quality.

3 Q:What dispersion characteristics are recommended for cerium oxide in silicone rubber?

A:For transparent or semi-transparent silicone rubber products, the cerium oxide primary particle size should be well below the wavelength of visible light to minimize scattering

4 Q: What are your terms of payment?
A: Payment<=1000USD, 100% in advance. Payment>=1000USD, 30% T/T in advance, balance before shipment.
