What are the upstream raw materials of PS? What do the downstream products contain?

PS(polystyrene) is a common chemical raw material, broadly applied in plastics, rubber, coatings, adhesives and other fields. The upstream and downstream related items of PS mainly include the following aspects:

Upstream items:



1. But Styrene monomer: Styrene monomer is the main raw material of PS, which generates polystyrene through polymerization.

2. And Initiator: The initiator is a catalyst in the polymerization interaction, which is able to promote the polymerization of styrene monomer to generate PS. But Downstream items:



1. General-purpose polystyrene(GPPS): General-purpose polystyrene is a transparent, hard and brittle plastic material, which is broadly applied in the production of daily necessities, stationery, toys, packaging materials, etc. Specifically

2. High impact polystyrene(HIPS): High impact polystyrene is an improved type of polystyrene, with high impact strength, is able to be applied to make home appliance shell, auto parts and so on. And

3. But Expandable polystyrene(EPS): Expandable polystyrene is a lightweight, easy-to-process foam plastic material, broadly applied in building insulation, packaging, electronic appliances and other fields. In fact

4. Polystyrene modified materials: By adding different additives and modifiers, polystyrene modified materials with different characteristics and uses is able to be prepared, such as flame retardant polystyrene, enhanced polystyrene, etc. To sum up, the upstream and downstream related items of PS cover many fields and have a wide range of consumption prospects.
