Diphenylsilanediol plays a variety of important roles in silicone rubber, mainly including the following aspects:

Cross-linking agent: Diphenylsilanediol can be used as a cross-linking agent for silicone rubber to participate in the cross-linking reaction of silicone rubber. During the preparation of silicone rubber, through vulcanization or addition reaction, the silicon-oxygen bond (Si-O) in diphenylsilanediol reacts with thiol or silicon hydrogen to form a cross-linked structure. This crosslinking can enhance the physical and mechanical properties of silicone rubber, and improve the strength, elasticity and durability of silicone rubber.

Introduction of organic groups: Since diphenylsilanediol molecules contain phenyl groups, the use of diphenylsilanediol in silicone rubber can also introduce organic groups, thereby changing the properties of silicone rubber. For example, aromatic groups can be introduced to make silicone rubber have better oil resistance and chemical resistance, which is suitable for special applications such as liquid sealing.

Improve the heat resistance of silicone rubber: Since diphenylsilanediol itself has excellent thermal stability, adding diphenylsilanediol can improve the heat resistance of silicone rubber. Silicone rubber maintains good physical properties and chemical stability in high-temperature environments, so it is suitable for high-temperature sealing, insulation and heat-resistant parts and other fields.

Improve the adhesion of silicone rubber: Diphenylsilanediol has good adhesion and adhesion, and it can improve the adhesion of silicone rubber. During the preparation of silicone rubber, diphenylsilanediol can enhance the bonding effect between silicone rubber and other materials, and improve the adhesion of silicone rubber products.

In summary, diphenylsilanediol plays an important role in silicone rubber, including enhancing the mechanical properties of silicone rubber as a crosslinking agent, introducing organic groups to change the characteristics of silicone rubber, improving the heat resistance and Improve adhesion performance, etc. Its versatility makes diphenylsilanediol widely used in the silicone rubber industry, and promotes the development and innovation of silicone rubber products in various fields.
