Hydroxyl silicone oil: The "Molecular Code" of Material Innovation

1. The unique structure endows the material with outstanding performance
Hydroxyl silicone oil, as an important organosilicon material, has a unique molecular structure, with repeated silicon-oxygen bonds as the main chain, methyl groups as side groups and hydroxyl groups as terminations. This structure enables hydroxyl silicone oil to endow materials with a variety of excellent properties and plays a key role in numerous industries such as silicone rubber, textiles, and leather.

2. Waterproof and heat-resistant, opening a new chapter in applications
In the textile field, hydroxyl silicone oil can construct a three-dimensional network structure on the surface of fibers, making the water contact Angle reach 150°, while the moisture permeability is greater than 5000g/m²/24h, endowing fabrics with excellent waterproof and breathable performance. In the aerospace field, sealing rings modified with hydroxyl silicone oil can be tested in a wide temperature range of -55 ℃ to + 200℃ for 50 cycles without hardening, with a compression set rate of less than 10%, which greatly enhances the reliability of aerospace equipment.

3. Performance regulation to optimize material quality
As the "master of performance regulation" for silicone rubber, hydroxyl silicone oil can act as a chain extender and crosslinking agent to work in synergy, making the molecular weight distribution of silicone rubber more uniform. After adding 0.5% hydroxyl silicone oil, the tensile strength of silicone rubber can be increased from 5.7MPa to 8.2MPa, and the elongation at break can be raised from 300% to 420%. In addition, the anti-yellowing technology of hydroxyl silicone oil can also delay thermal oxidation degradation. After being placed in an oven at 150℃ for 72 hours, the light transmittance still remains at 92%.

4. The market has broad prospects and huge development potential
According to relevant reports, the global market size of hydroxyl silicone oil reached 2.579 billion yuan in 2024, with the Chinese market size reaching 686 million yuan. It is expected that by 2030, the global market size will reach 3.733 billion yuan, with an average annual compound growth rate of 6.36%. With the continuous improvement of material performance requirements in various industries, the market demand for hydroxyl silicone oil is expected to further expand.
