Semi-extinction chip is a raw material for chemical production, which is mainly used in the production of polymers. The upstream and downstream related products of semi-extinction slices mainly include the following aspects:

upstream products:

1. Petroleum: Petroleum is one of the main raw materials of semi-extinction slices. Chemicals such as benzene and ethylene can be obtained through petroleum cracking and other methods, and further converted into polymer monomers.
2. Natural gas: Natural gas can also be used as a raw material for semi-extinction slices, and further synthesized to obtain polymer monomers through processes such as the production of acetylene from natural gas.

downstream products:

1. Polymer: semi-extinction chips can be used as raw materials for polymer production, such as polypropylene, polyethylene, etc. These polymers can be widely used in plastic products, fibers, films and other fields.
2. Functional materials: Semi-extinction slices can also be used to produce some functional materials, such as functional film materials, photoelectric materials, etc. These materials have a wide range of applications in new energy, electronic information and other fields.

In particular, semi-extinction chips are widely used in polymer production. For example, in the production of polypropylene, semi-extinction chips can be used as comonomers to copolymerize with propylene to obtain polypropylene products with different performance indicators. These polypropylene products can be used in injection molding, extrusion, blow molding and other processing processes to produce a variety of plastic products.

In addition, semi-extinction chips can also be used to produce some functional polymers. For example, by introducing a functional monomer, a polymer material with functions such as antibacterial, antioxidant, and ultraviolet resistance can be obtained. These materials have a wide range of applications in food packaging, medical equipment and other fields.

In short, as an important raw material for the production of chemical products, semi-extinction slices have a wide range of upstream and downstream related products, involving many fields.
