GPPS (general-purpose polystyrene) is a plastic material widely used in the field of chemical production. It has many upstream and downstream related products, and some of the main upstream and downstream products will be described in detail below.

upstream products:

1. Styrene monomer: The main raw material of GPPS is styrene monomer, which is a colorless and transparent oily liquid with aromatic odor. Styrene monomer is polymerized to form polystyrene.

downstream products:

1. High impact polystyrene (HIPS):HIPS is a modified product of GPPS. By introducing rubber components, the impact strength of polystyrene is improved. HIPS is widely used in home appliances, automobiles, construction and other fields.
2. Expandable polystyrene (EPS):EPS is a foaming product of GPPS, which has the advantages of light weight, heat preservation and earthquake resistance, and is widely used in packaging, construction, cold chain transportation and other fields.
3. Polystyrene foam board (XPS):XPS is a kind of polystyrene foam material with closed cell structure, which has excellent thermal insulation performance and environmental protection, and can be used in building insulation, cold chain logistics and other fields.
4. ABS resin: ABS resin is a terpolymer of acrylonitrile, butadiene and styrene. It has excellent impact resistance, heat resistance and processing performance. It is widely used in home appliances, automobiles, electronic products and other fields.

In general, GPPS has a wide range of upstream and downstream related products. With the continuous development of science and technology, the application field of GPPS and its related products will continue to expand.
