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).

High Impact Poly Styrene (HIPS)


HIPS (High Impact Polystyrene), also known as PS (Polystyrene), is an amorphous thermoplastic material, used in lower heat applications.

Phthalic Anhydride (PA)


It is the anhydride of phthalic acid. Phthalic anhydride is a principal commercial form of phthalic acid.
