Hiki ke hoʻokaʻawale ʻia nā plastic styrene i polystyrene (PS), ABS, SAN a me SBS.He kūpono nā plastic type Styrene no ka hana ʻana i nā huahana e hoʻohana ana i nā mahana ambient ma lalo o 80 degere Celsius
ʻO ka PS (polystyrene) he mea ʻawaʻawa ʻaʻole waihoʻoluʻu ʻulaʻula ʻulaʻula ʻulaʻula ʻole, hiki ke puhi ʻia, ka huʻa palupalu i ke ahi, a hele pū me ka uahi ʻeleʻele.ʻO kona ʻano maikaʻi ʻelua a me ka paʻakikī, ke kūpaʻa compressive kiʻekiʻe, ka insulation maikaʻi.Hoʻokaʻawale ʻia ʻo PS i nā polystyrene GPPS āpau, polystyrene EPS hiki ke hoʻopau ʻia, polystyrene HIPS kiʻekiʻe.ʻO ka GPPS ka mea maʻamau a palupalu.Hana ʻia ʻo HIPS me ka hui pū ʻana o PS a me polybutadiene, e hāʻawi iā lākou i ʻoi aku ma mua o ʻehiku mau manawa o ke kūpaʻa compressive a me ka ikaika o GPPS.Hana ʻia ʻo EPS me nā ʻāpana master PS i hoʻonui ʻia e ke kinoea a i ʻole ka mahu.He ʻano ʻōhū i loaʻa he 2% mea a me 98% ea.He māmā a he adiabatic.
