The domestic rare earth heat-resistant agent for rubber has been successfully developed, which can replace imports

China Rubber Net recently learned from the Baotou Rare Earth Research Institute that the rare earth separation and application team of the institute and the Beijing Aviation Materials Research Institute of China Aviation Development have successfully developed a light rare earth heat-resistant agent product for silicone rubber and fluorosilicone rubber
.

The product has been tested and verified by the Beijing Aviation Materials Research Institute of China Aviation Development, which can effectively increase the use temperature of silicone rubber and fluorosilicone rubber materials and improve their heat resistance levels
.

Silicone rubber has a wide range of applications in the fields of electrical, electronics, office equipment, automobiles, construction, medical, food and artificial organs due to its excellent weather resistance, high and low temperature resistance, electrical insulation, radiation resistance, and biological inertness.

.

According to China Rubber Net, under aerobic and high temperature environments, silicone rubber materials mainly undergo main chain degradation and side chain methyl oxidation reactions, resulting in a decrease in the mechanical properties of silicone rubber
.

Rare earth resources are precious strategic resources.
However, the application fields of light rare earth lanthanum and cerium resources are limited, the resource utilization rate is low, the product backlog is large, and the market price has been low for a long time.
The core reason is insufficient development and application
