Polystyrene (PS) ke polymer ea maiketsetso e entsoeng ka styrene monomer, e leng thermoplastic e hlakileng, ea amorphous, nonpolar commodity thermoplastic eo ho leng bonolo ho e sebetsa le e ka fetoloang habonolo ho palo e kholo ea lihlahisoa tse felileng joaloka foam, lifilimi le maqephe. .Ke e 'ngoe ea polasetiki e kholo ka ho fetisisa ea thepa, e nang le hoo e ka bang liperesente tse supileng tsa mmaraka o felletseng oa thermoplastic.
PS ke insulator e ntle haholo ea motlakase, e na le khanya e ntle haholo ea optical ka lebaka la khaello ea kristale, 'me e na le khanyetso e ntle ea lik'hemik'hale ho li-acid tse hlapollotsoeng le metheo.Leha ho le joalo, polystyrene e na le mefokolo e mengata.E hlaseloa ke metsoako ea hydrocarbon, e na le oksijene e fokolang le ho hanyetsa UV, 'me e batla e brittle, ke hore, e na le matla a fokolang ka lebaka la ho satalla ha mokokotlo oa polymer.Ho feta moo, moeli oa mocheso oa eona o ka holimo bakeng sa tšebeliso e tsoelang pele o batla o le tlase ka lebaka la khaello ea kristale le mocheso oa eona o tlase oa phetoho ea likhalase tse ka bang 100 ° C.Ka tlase ho Tg ea eona, e na le matla a mahareng ho isa holimo (35 - 55 MPa) empa matla a ts'usumetso e tlase (15 - 20 J / m).Leha ho na le mefokolo ena kaofela, li-polymer tsa styrene ke lipolasetiki tsa thepa e ntle haholo.
Letlapa la polystyrene hangata le tšesaane ebile le boreleli ho feta letlapa la acrylic empa hangata le bitsa chelete e nyane ho feta lipolasetiki tse ling.E na le ponaletso e phahameng (ea bobeli feela ho maqephe a acrylic a transmittance e khanyang), ho hanyetsa ha eona, ho hanyetsa boemo ba leholimo le ho hanyetsa botsofali ho mpe ho feta plexiglass, thepa ea mochine le thepa ea ho sebetsa ha mocheso ha e tšoane le plexiglass, boima bo tšoana le plexiglass acrylic, metsi. ho monya le ho eketsa mocheso oa coefficient e ka tlase ho plexiglass acrylic, empa theko ea eona e tlase ho feta plexiglass acrylic.
Polystyrene ke thepa ea khetho bakeng sa lits'ebetso tse ngata tse kenyelletsang ho paka lijo, thepa ea polasetiki ea bareki e lahloang hammoho le likarolo tsa lisebelisoa tsa optical, tsa elektroniki / tsa motlakase le tsa bongaka.
