Kazhinji,polystyrenei polymer inonhuhwirira yakagadzirwa kubva ku monomer styrene, inotorwa kubva ku benzene uye ethylene, ese ari maviri e petroleum zvigadzirwa.Polystyrene inogona kuva yakasimba kana kupupa.Polystyreneis a colorless, transparent thermoplastic, iyo inowanzoshandiswa kugadzira foam board kana beadboard insulation uye rudzi rwe loose-fill insulation ine mabeads madiki epolystyrene.Polystyrene furoari 95-98% mweya.Mafuro epolystyrene akanaka ekupisa anodzivirira saka anowanzo shandiswa sezvivakwa zvekuvakisa, senge mukuisa mafomu ekongiri uye masisitimu ekuvakisa mapaneru ekuvaka.Yakawedzerwa (EPS)uyeyakawedzera polystyrene (XPS)ese ari maviri akagadzirwa kubva ku polystyrene, asi EPS inoumbwa nediki mabeads epurasitiki akasanganiswa pamwechete uye XPS inotanga sechinhu chakanyungudutswa chinotsikirirwa kunze kwechimiro kuita mapepa.XPS inonyanya kushandiswa sefoam board insulation.
Yakawedzerwa polystyrene (EPS)ivhu rakaoma uye rakaoma, rakavharika-sero furo.Zvishandiso zvekuvaka uye zvekuvaka zvinokwana zvikamu zviviri muzvitatu zvekudiwa kwe polystyrene yakawedzerwa.Inoshandiswa pakuvhara kwe (cavity) madziro, matenga uye kongiri pasi.Nekuda kwehunyanzvi hwekuita senge huremu hwakaderera, kusimba, uye kuumbwa,yakawedzera polystyreneinogona kushandiswa mumhando dzakasiyana-siyana dzekushandisa, semuenzaniso matireyi, ndiro uye mabhokisi ehove.
Kunyangwe ese akawedzera uye akawedzera polystyrene ane yakavharwa-sero chimiro, iwo anopindika nemamorekuru emvura uye haagone kutorwa sevhavha yemhute.Mu polystyrene yakawedzerwa mune mikaha yepakati pakati peakavharika-sero pellets akawedzera ayo anoumba network yakavhurika yematanho pakati pemabonde akasungwa.Kana mvura ikagwamba kuita aizi, inokura uye inogona kukonzera kuti polystyrene pellets ibve kubva mufuro.
