EPS(Expandable Polystyrene, expandable polystyrene) is a kind of raw material widely used in the field of chemical production. In the upstream and downstream related products of EPS, the upstream products mainly include styrene monomer, while the downstream products include various plastic products, building materials, packaging materials, etc. This article will detail the upstream and downstream associated products of EPS.

1. upstream related products

styrene monomer is the main raw material of EPS, used to produce expandable polystyrene. Styrene monomer is a colorless transparent oily liquid, with aromatic odor, insoluble in water, soluble in ethanol, ether and other organic solvents. Styrene monomer is mainly prepared by alkylation of ethylene and benzene, and can also be obtained by other synthetic methods.

2. downstream related products

1. Plastic products

EPS can be used as raw materials for plastic products, widely used in the production of various plastic products, such as insulation boards, insulation boxes, toys, tableware, home appliance shells, etc. Because EPS has the advantages of light weight, easy processing and low price, it is widely used in the field of plastic products.

2.

of building materials EPS has a wide range of applications in the field of construction, mainly used as thermal insulation materials. EPS insulation board has the advantages of excellent thermal insulation performance, convenient construction and light weight, and is widely used in the field of building exterior wall insulation, roof insulation and so on.

3. Packaging material

EPS as an excellent packaging material, is widely used in electronic products, medical equipment, glass products and other fields of packaging. Because of its good seismic performance, moisture resistance and thermal insulation performance, it can effectively protect the packaged goods.

In short, as an important raw material for the production of chemicals, EPS has a wide range of upstream and downstream related products, involving plastic products, building materials, packaging materials and other fields.
