In the field of chemical production raw materials, semi-extinction products usually refer to chemical raw materials with a certain extinction effect, which are mainly used to adjust the gloss and surface characteristics of the products. The upstream and downstream related products of semi-extinction products mainly include the following categories:

1. Upstream raw material

(1) Petroleum: Petroleum is the basic raw material of many chemicals, through petroleum cracking and separation can obtain a variety of olefins, aromatics and other basic chemical raw materials, and then used to produce semi-extinction products.

(2) Natural gas: Natural gas is also an important chemical raw material. Basic chemicals such as methanol and acetylene can be produced through natural gas, and semi-extinction products can be obtained through further processing.

(3) Coal: After gasification and liquefaction, coal can be processed to obtain synthetic gas, alcohols and other chemicals, which are then used to produce semi-extinction products.

2. Downstream product

(1) Coating: Semi-matte products can be used as one of the raw materials of the coating, used to adjust the gloss and surface characteristics of the coating, and improve the appearance, texture and corrosion resistance of the coating.

(2) Plastics: Semi-extinction products can also be used in plastic production to improve the gloss and surface characteristics of plastics, and improve the appearance quality and performance of plastic products.

(3) Ink: Semi-matte products can be used as additives for ink, adjust the printing performance and color of ink, and improve the printing quality and gloss of printed matter.

In summary, the upstream and downstream related products of semi-extinction products cover many fields, including basic raw materials such as oil, natural gas, and coal, as well as downstream applications such as coatings, plastics, and inks.
