styrene rau polystyrene,
Styrene rau PS, Styrene siv hauv Kev Tsim Cov Polystyrene, Styrene siv los tsim polystyrene resins,
Polystyrene (PS) yog ib qho polymer ua los ntawm monomer styrene, cov kua hydrocarbon uas yog ua lag luam los ntawm cov roj av.
Polystyrene tuaj yeem ua tau zoo lossis foamed.General-purpose polystyrene yog ntshiab, tawv, thiab nkig.Nws yog ib qho pheej yig resin rau ib chav tsev qhov hnyav.Nws yog ib qho tsis zoo rau cov pa oxygen thiab dej vapor thiab muaj cov ntsiab lus melting tsawg.Polystyrene yog ib qho ntawm cov yas siv ntau tshaj plaws, qhov ntsuas ntawm nws cov khoom yog ntau lab tons hauv ib xyoos.Polystyrene tuaj yeem ua pob tshab, tab sis tuaj yeem ua xim nrog cov xim.
