Hydroxysilicone oil: the "hidden champion" in the field of high-performance materials
Hydroxysilicone oil, chemical name α, ω - dihydroxypolydimethylsiloxane, is an organic silicon polymer with Si-O-Si as the main chain and active hydroxyl groups at both ends. Its unique molecular structure endows it with excellent high and low temperature resistance, chemical stability, hydrophobicity, and surface activity, playing an irreplaceable role in multiple industrial fields and can be regarded as the "hidden champion" in the field of high-performance materials.


Invisible skeleton of silicone rubber and sealing materials
In the silicone rubber industry, hydroxyl silicone oil is an indispensable crosslinking agent. The hydroxyl groups at both ends of its molecule can undergo condensation reactions with silane coupling agents or hydrogen containing silicone oil to form a three-dimensional network structure, significantly improving the mechanical strength, heat resistance, and aging resistance of silicone rubber. For example, in the preparation of high-temperature vulcanized silicone rubber (HTV), the addition of hydroxyl silicone oil can maintain the elasticity of rubber products in a wide temperature range of -60 ℃ to 250 ℃, which is widely used in aerospace seals, automotive engine gaskets, and other fields. In addition, hydroxyl silicone oil can also be used for the preparation of liquid silicone rubber (LSR). By adjusting its molecular weight and hydroxyl content, customized products can be produced to meet different hardness, transparency, and flowability requirements.


Molecular Magician of Surface Treatment and Functional Coatings
The hydroxyl group of hydroxyl silicone oil endows it with excellent reactivity, making it an ideal material in the field of surface treatment. After coating hydroxyl silicone oil on the surface of substrates such as glass, metal, and fabric, it can form hydrophobic, anti fouling, and anti-static organic silicon films through chemical reactions. For example, coating hydroxyl silicone oil treatment agent on the surface of building glass can achieve a water droplet contact angle of over 110 ° and achieve self-cleaning effect; On the surface of electronic components, hydroxyl silicone oil can form an insulating and moisture-proof protective layer, enhancing the reliability of the product. In addition, hydroxyl silicone oil can also be used for fiber modification, endowing fabrics with properties such as softness, wrinkle resistance, and easy stain removal, and is widely used in high-end clothing and home textile fields.


The 'Green Pioneer' of Environmental Protection and Sustainable Technologies
With the global attention to environmental protection and sustainable development, the green properties of hydroxy silicone oil are becoming increasingly prominent. Its biocompatibility and low toxicity make it potential in the biomedical field, such as as as a drug carrier or lubricant for medical devices. In industrial production, hydroxyl silicone oil can be synthesized solvent-free through hydrolysis condensation reaction, reducing volatile organic compound (VOC) emissions. In addition, the weather resistance and chemical corrosion resistance of hydroxyl silicone oil make it an ideal component for environmentally friendly coatings and sealants, helping industries such as construction and automotive achieve low-carbon transformation. In the future, with the integration of nanotechnology and biotechnology, hydroxyl silicone oil is expected to open up new application spaces in cutting-edge fields such as smart materials and flexible electronics.
