Ethyl orthosilicate is an active non-ionic surfactant.

Ethyl orthosilicate is a specialty silicone oil produced by reacting organosiloxanes with allyl polyethers. It serves as a reactive, nonionic surfactant capable of miscibility in water, aromatic hydrocarbons, and alcohols at any ratio. This compound exhibits exceptional wash resistance, antistatic properties, and softening effects, making it particularly well-suited for the production of shampoos and hair conditioners.

From a content perspective, it includes two subdirectories: the National Catalogue of Industries Encouraging Foreign Investment (National Catalogue), which applies nationwide and outlines policies to promote foreign investment in specific industries; and the Catalogue of Advantageous Industries for Foreign Investment in Central and Western Regions (Central-Western Catalogue), primarily targeted at the central-western and northeastern regions, serving as a regional policy framework to encourage foreign investment.

After a sharp surge, it plunged—organic silicon oil byproducts' prices have been on a roller-coaster ride.

Industry insiders reveal that shipments of methyl and trimethyl silicones are currently sluggish, driving prices to continuously decline. As a result, since May, both siloxanes and silazanes have begun showing downward trends—siloxane prices have plummeted from over 110,000 yuan per ton in April 2018 to around 60,000 yuan today, while trimethyl silicones have dropped from more than 70,000 yuan to just over 30,000 yuan. In a matter of just a few months, prices have nearly halved. Meanwhile, organic silicon byproducts have seen price hikes that were truly unexpected—and now, the biggest pain is being felt by traders who previously stocked up at higher levels.

It is well known that the strength of silicone rubber vulcanizates without reinforcing fillers is quite low. In practical applications, most silicone rubbers are used as composite materials reinforced with fillers. Commonly employed reinforcing fillers for silicone rubber include fumed silica or precipitated silica. Within a suitable range, the strength of vulcanized silicone rubber increases proportionally as the amount of silica filler rises. Notably, the surface of silica particles contains a significant number of silanol groups, which form hydrogen bonds with the organosilicon polymer. This interaction leads to thickening of liquid silicone rubber compounds and structuring of semi-solid formulations. As a result, the proportion of silica filler added is inherently limited.
