Since the advent of silicone elastomer in the 1940s, its applications have been continuously developed by engineers to meet the various needs of human development, from traditional keyboard buttons, medical catheters, kitchen utensils, to the recently popular mascots"Bing Tuntun" .Silicone elastomer connects closely with peoples's life. During its production, various functional additives need to be added to achieve its designed performance. Among them, one of  the additives called Filler treatment  agents plays an important role in maintaining the excellent physical and chemical properties of silicone elastomer especially the excellent processability after long-term storage.

Noun interpretation: Structured

During the storage process of silicone rubber, the phenomenon where the gel is formed in the compound due to the interaction of hydroxyl groups on the surface of silica, leading to agglomeration, or the interaction with the base polymer to form a three-dimensional network structure, resulting in increased viscosity, decreased mechanical properties, and even loss of processability, is collectively referred to as "structuralization".

Noun interpretation: structure control agent

To address the "structural" issue affecting the service life and performance of silicone rubber, surface treatment of silica is conducted using agents that reduce the surface active hydroxyl groups on the filler, known as structure control agents. Common structure control agents include hydroxyl silicone oil, alkoxysilane, and silazane. Hydroxyl silicone oil and alkoxy-based structure control agents exhibit good treatment effects and cost advantages for low specific surface area silica, but they also have drawbacks such as poor system stability, tendency for the compound to become sticky, and high usage. Small molecule silazanes with high reactivity offer more prominent performance advantages in high-end applications. Next, let me introduce two products, XY-602 and XY-803, from Xinyaqiang that are highly praised by customers both domestically and internationally in the field of powder processing.
