The Si-H bond activity empowers hydrogen-containing silicone oil in multiple fields to become an invisible core in high-end manufacturing
Among the family of silicone materials, hydrogen-containing silicone oil, although not as intuitive in application scenarios as ordinary silicone oil, has become an indispensable core material in high-end manufacturing fields due to the unique activity of the Si-H bond in its molecular chain. From medical supplies to new energy components, its characteristic of regulating material properties through chemical reactions is gradually expanding the application boundaries, highlighting the profound value of silicone materials.


1. Core feature: The Si-H bond dominates the reactivity
The core difference between hydrogen-containing silicone oil and common dimethyl silicone oil lies in its chemical reactivity as the core competitiveness. Dimethyl silicone oil relies on its physical inertness to achieve surface functions such as lubrication and defoaming. Meanwhile, the Si-H bonds in hydrogen-containing silicone oil can be modified through addition, condensation and other reactions to construct a stable molecular structure or achieve material modification. Moreover, the reaction process has no by-products and a low shrinkage rate, which meets the requirements of environmental protection and high-precision manufacturing, laying the foundation for its cross-field application.


2. Crosslinking and curing: Key support for the molding of high-end materials
As a core raw material for crosslinking and curing, hydrogen-containing silicone oil plays a crucial role in products such as addition-cured liquid silicone rubber and electronic potting compound. Under the action of a catalyst, it reacts with vinyl-containing silicone oil to form a three-dimensional network structure, solidifying the liquid system into an elastomer or gel. It is widely used in scenarios such as medical catheters, baby pacifiers, and LED packaging, ensuring product safety while meeting the strict requirements for material stability in high-precision manufacturing.


3. Surface modification: Endow materials with long-lasting functional properties
In the fields of textiles, leather and construction, hydrogen-containing silicone oil demonstrates unique advantages as a surface modifier. It can react with the hydroxyl groups on the surface of fibers and stones to form a dense protective film. This not only endows fabrics with a soft hand feel but also ensures long-lasting water and stain resistance even after more than 50 washes. It has become a core finishing agent for high-end outdoor clothing and building waterproofing projects, solving the pain point of traditional modified materials' lack of durability.


4. Emerging Expansion: Empowering the new energy and semiconductor industries
With the upgrading of high-end manufacturing, the application of hydrogen-containing silicone oil in the fields of new energy and semiconductors has continued to make breakthroughs. Low-volatile products can be used as passivation layers on silicon wafers and precursors for battery packaging materials. With their low volatility and high stability, they are suitable for extreme working conditions of new energy vehicles ranging from -50℃ to 200℃, while ensuring the long-term reliability of semiconductor chip packaging. They have become an important support for the development of emerging industries.
