Organic Silicon Industry Chain


The industrial chain of the organic silicon industry mainly consists of "organic silicon raw materials organic silicon monomers organic silicon intermediates organic silicon products". The synthesized mixed methyl monomers are finely separated, hydrolyzed, and cracked to generate organosilicon based polymers, which are then further processed and produced into various organosilicon products.

The upstream of the organic silicon industry mainly consists of basic chemical raw materials such as metallic silicon, hydrogen chloride, and chloromethane. Silicone rubber, silicone oil, silane coupling agent, silicone resin and other end products are polymerized from organic silicon intermediates. Among them, silicone rubber and silicone oil account for the largest proportion, reaching 66% and 22% respectively.

Dimethyldichlorosilane is the most widely produced monomer in the organosilicon industry, with its upstream raw materials being metallic silicon and chloromethane, and downstream synthesizing organosilicon DMC Before producing end products such as silicone rubber, silicone resin, and silicone oil, intermediates such as organosilicon D4 are used.

Among them, silicone rubber accounts for the largest proportion, reaching 66.9%, but its special properties as a material additive cover multiple fields such as building materials, electronic appliances, aerospace, daily chemical, textile printing and dyeing, and new energy vehicles.

From the perspective of downstream emerging application markets, in the context of "carbon neutrality", the emerging energy market will experience explosive growth in the coming years. By 2025, the annual installed capacity of photovoltaics in China will reach 80GW (48GW in 2020), and the production of new energy vehicles will reach 6 million units. The prosperity of related industries will drive the explosion of the organic silicon application market in the fields of new energy vehicles and photovoltaics.
