styrene for PS
styrene for PS,
styrene for Polystyrene，styrene used to produce polystyrene resins，styrene used in the production of polystyrene,
Polystyrene (PS) is a synthetic polymer made from a chain of styrene monomers and is a synthetized from petrochemical byproducts. The polystyrene chemical formula wasn’t discovered before 1839, and a century will pass before its synthesis process could be industrialized
Invented in 1944, expanded polystyrene (PSE or XPS) was first used as an insulator in buildings, construction, transports and food-processing industry.
Today Polystyrene is essential in many domains and industries.
The ultimate asset of this material: it is easily recyclable by a granulation process.
