It can be injected extruded or blow molded. Styrene the liquid hydrocarbon from which epf is made was extracted from storax balsam in the late 19th century which comes from a tree in asia minor called the oriental sweet gum.

Polystyrene Wikipedia

Styrene is produced from ethylene and benzene.

Where does polystyrene come from. By this term we mean expanded polystyrene eps. Created from styrene polystyrene is a stiff and transparent synthetic resin that can be combined with other materials to add rigidity to them or foamed by itself and made into insulation packaging materials and food service ware. Polystyrene is a strong plastic created from ethylene and benzene.

Most of us recognize polystyrene in the form of styrofoam used for beverage cups and packaging peanuts. It is an inexpensive resin per unit weight. When ethylene passes into benzene in presence of an aluminum trichloride catalyst ethylbenzene is produced which on passing over a catalyst such as iron oxide or magnesium oxide at high temperature gets converted into styrene and hydrogen.

Test data submitted to fda indicated that the migration of styrene from polystyrene foodservice products is tiny and expected to be significantly below the safety limits set by fda itself 10 000 times less than fda s acceptable daily intake level. General purpose polystyrene is clear hard and rather brittle. Where does styrene come from.

It is used to produce many products for industrial and consumer use. The polymer itself comes from generally polymerizations of styrene a common method might be a free radical type of polymerization or zeiglar natta. Polystyrene is one of the best known synthetic polymers there are polyethylene polypropylene and polyester among others.

Styrene is produced from ethylene and benzene. Polystyrene comes from benzene and ethylene and both are produced from stream cracking of refined petroleum. In solid form it is a colorless and rigid plastic but it may also be returned to a liquid state by heating and used again for molding or extrusion.

Polystyrene can be solid or foamed. Polystyrene is a type of polymer with thermoplastic properties produced from the petroleum derived monomer styrene.
