Dimethyl silicone oil: a "evergreen tree" in traditional fields and a breakthrough in emerging markets
Dimethyl silicone oil (polydimethylsiloxane), as the most mature silicone oil category, has a global market size of 667 million US dollars in 2024 and is expected to increase to 784 million US dollars in 2031. Its applications span across traditional fields such as chemical engineering, electronics, and construction, and open up new growth poles in the cosmetics industry. For example, Anasun sunscreen uses its film-forming properties to enhance waterproof performance, while Lifuquan B5 cream reduces irritation by encapsulating acidic components in silicone oil.
Technological upgrades drive product iteration. Low viscosity dimethyl silicone oil meets the requirements of high-speed electronic packaging, while high-purity products are used for chip photoresist stripping. Companies such as Dow Corning and Shinetsu Chemical have developed special silicone oils with temperature resistance exceeding 300 ℃ through nanocomposite technology, expanding the market for thermal management of new energy vehicle batteries.
