Ngokubanzi,polystyreneyipolima emnandi eyenziweyo eyenziwe kwi-monomer styrene, ephuma kwi-benzene kunye ne-ethylene, zombini iimveliso zepetroleum.I-Polystyrene inokuba yomelele okanye ibe negwebu.Ipolystyreneyi-thermoplastic engenambala, transparent, edla ngokusetyenziswa ukwenza i-foam board okanye i-beadboard insulation kunye nodidi lwe-loose-fill insulation ebandakanya amaso amancinci e-polystyrene.Polystyrene amagwebuyi 95-98% yomoya.I-Polystyrene foams zi-insulators ezilungileyo ze-thermal kwaye ke ngoko zihlala zisetyenziswa njengezinto zokwakha zokugquma, ezifana neefom zekhonkrithi ezigqumayo kunye nezakhiwo ze-insulated panel zokwakha.Yandisiwe (EPS)kwayei-polystyrene ekhutshiweyo (XPS)zombini zenziwe nge-polystyrene, kodwa i-EPS yenziwe ngamaso amancinane eplastiki adityanisiweyo kunye kwaye i-XPS iqala njengento etyhidiweyo etyhidiweyo ngaphandle kwefomu ibe ngamashiti.I-XPS idla ngokusetyenziswa njenge-foam board insulation.
Ipolystyrene eyandisiweyo (EPS)lugwebu oluqinileyo kwaye luqinile, luvaliweyo.Ulwakhiwo nolwakhiwo lubalelwa malunga nesibini kwisithathu semfuno yepolystyrene eyandisiweyo.Isetyenziselwa ukugquma kweendonga (umngxuma), uphahla kunye nemigangatho yekhonkrithi.Ngenxa yeepropathi zayo zobugcisa ezinjengobunzima obuphantsi, ukuqina, kunye nokubumba,i-polystyrene eyandisiweyoingasetyenziswa kuluhlu olubanzi lwezicelo, umzekelo iitreyi, iipleyiti kunye neebhokisi zeentlanzi.
Nangona zombini i-polystyrene eyandisiweyo kunye ne-extruded inesakhiwo seseli evaliweyo, iyakwazi ukungena kwiimolekyuli zamanzi kwaye ayinakuthathwa njengesithintelo somphunga.Kwi-polystyrene eyandisiweyo kukho izikhewu phakathi kweepellets ezivaliweyo ezandisiweyo ezenza uthungelwano oluvulekileyo lwemijelo phakathi kweepellets ezidibeneyo.Ukuba amanzi aba ngumkhenkce, ayanda kwaye anokubangela ukuba iipellet zepolystyrene ziqhawuke kugwebu.
