Kev nthuav dav polystyrene (EPS) muaj qhov zoo xws li cov txheeb ze tsawg (1.05 g / cm³), tsis tshua muaj thermal conductivity, tsis tshua muaj dej nqus, cuam tshuam thiab kev vibration tsis kam, rwb thaiv tsev kub, suab rwb thaiv tsev, ya raws, kev co damping, thiab zoo heev dielectric zog. Nws yog dav siv los ua cov khoom ntim khoom shockproof rau cov tshuab, cov cuab yeej, cov khoom siv hauv tsev, cov khoom siv tes ua, thiab lwm yam khoom tsis zoo thiab muaj txiaj ntsig, nrog rau kev ntim khoom noj ceev.
Txawm li cas los xij, qhov tsis txaus ntseeg ntawm EPS tau ua rau muaj kev nce hauv EPS pov tseg, ua rau muaj "dawb paug" thiab ua rau muaj kev puas tsuaj ntawm ib puag ncig ecological. Kev rov ua dua tshiab ntawm EPS tau txais kev pom dav dav.
