Polystyrene — solid, rigid, amorphous polymer, otonositsya to class of thermolayers. Polystyrene is well painted and processed in the mechanical ways. The Dvukhosnooriyentirovanny styroflex possesses excellent transparency.
Softening point of PS makes 90 — 95 °C. The oriented polystyrene has average gas permeability (above than at software, but below, than at PENP), but high vapor permeability. Vapor permeability of PS quickly goes down at temperatures below 0 °C that allows to use it for packaging of products at low temperatures. From the oriented styroflex by method of thermoforming to receive products of difficult configuration.
Impact polystyrene (OOPS) represents block styrene copolymer with rubber. In unmodified state polystyrene — brittle material, and its specific impact strength it is insufficient for many applications.
