In the field of new silicone-based materials, single-ended hydrogen-containing silicone oil is becoming a key additive due to its unique structure. One end of the molecular chain of this type of silicone oil is an inert methyl group, and the other end is capped with dimethylsiloxy. It not only retains the stable characteristics of polydimethylsiloxane but also has excellent compatibility, enabling efficient integration with double-ended and branched hydrogen-containing silicone oils.
Its core value lies in its performance regulation capability: as a "regulator" for addition-cured silicone rubber and silicone gel, it can precisely adjust the material's hardness, elongation at break, and modulus, meeting diverse needs from soft seals to elastic gels. Meanwhile, through the hydrosilylation reaction, it can combine with compounds containing Si-CH=CH₂ bonds, introducing inert polydimethylsiloxane segments into the molecular end groups or side chains, providing a new path for the functional modification of new materials.
Currently, single-ended hydrogen-containing silicone oil has been widely used in fields such as electronic packaging, medical consumables, and high-end coatings. It plays an important role in improving the weather resistance and flexibility of products, promoting the development of silicone-based materials towards more refined and high-functional directions.
