With the rapid development of the automotive, electronics, power, and high-temperature materials industries, silicone rubber is widely used due to its excellent heat resistance, electrical insulation, and stability. However, high-temperature silicone rubber systems often face challenges during processing and use, such as structural coarsening, unstable viscosity, and decreased mechanical properties. These problems are closely related to the "structure control agents" in the system. In recent years, dimethyl diethoxysilane has become a highly regarded modifying agent in the industry due to its unique chemical structure.

Dimethyl diethoxysilane is a silane compound with a simple structure and moderate reactivity, making it an excellent structural regulator for organosilicon systems. When added to silicone rubber formulations, it can undergo a moderate condensation reaction with polysiloxane segments, thereby inhibiting excessive cross-linking between segments and preventing "structuralization" of the material at high temperatures or during storage. Due to this property, it is gradually replacing traditional hydroxyl silicone oils and becoming an important modifying raw material in the field of high-temperature silicone rubber.

Furthermore, this product has a moderate boiling point, is transparent and easily soluble, and boasts a purity of ≥99%, making it easier to control the amount of material added and the reaction process during processing. By optimizing the flowability and stability of high-temperature silicone rubber, dimethyldiethoxysilane significantly improves the molding performance and final physical structure of the product, making it widely used in cable sheathing, automotive parts, heat-resistant gaskets, and other fields.

With the increasing demand for high-performance silicone rubber, this fine silane additive is gradually becoming an indispensable key raw material in the industry.
