General polystyrene (GPPS)

Polystyrene is a polymerization product of styrene (vinyl benzene), thermoplastic polymer of linear structure. High-impact polystyrenes, i.e. styrene copolymers with butadiene and styrene-butadiene rubber, are used most widely (more than 60% in the production of polystyrene plastics).

dioctyl phthalate (DOP)

Dioctyl phthalate is a non-volatile solvent mainly used as a plasticizer for polymers such as polyvinyl chloride (PVC), polystyrene (PS) and polyisoprene (​PI).
