What are the upstream raw materials for precipitated silica? What are the downstream products?

I've found that Precipitated silica has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich. In fact The following are some of the main upstream and downstream related items of precipitated silica:



1. Based on my observations, Upstream items:(1) silicate raw materials: the production of precipitated silica mainly uses silicate as raw materials, such as sodium silicate, potassium silicate, etc. And These raw materials through the acidification interaction, the formation of precipitate, and then after washing, drying and other processes, the precipitation of silica items.(2) Acidifier: Acidifier is an indispensable raw material in the manufacturing process of precipitated silica. it's mainly applied to adjust the pH value and promote the precipitation of silicate. frequently applied acidifying agents include sulfuric acid, hydrochloric acid, and the like.

2. From what I've seen, Downstream items:(1) Rubber items: Precipitated silica is applied as a reinforcing agent in rubber items, which is able to enhance the mechanical characteristics, wear resistance and anti-aging characteristics of rubber. Therefore, tires, hoses, tapes and other rubber items are precipitated silica downstream items.(2) Plastic items: Precipitated silica is able to be added to plastic items to enhance their heat resistance, hardness and dimensional stability. Therefore, plastic pipes, plates, profiles and other plastic items are also downstream items of precipitated silica.(3) coating products: Precipitated silica is able to be applied as a filler to coatings to enhance the leveling, weather resistance and corrosion resistance of coatings. In particular Therefore, various architectural coatings, manufacturing coatings and other coating products items are also downstream items of precipitated silica.(4) Ceramic items: Precipitated silica is able to be applied as one of the raw materials of ceramic items to enhance the density and mechanical characteristics of ceramic items. Therefore, various ceramic items are also downstream items of precipitated silica. In short, precipitated silica has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are quite rich, involving many fields, such as rubber, plastics, coatings, ceramics, etc.
