EPS muaj tshuaj lom neeg ruaj khov thiab kub tsis kam. Nws qhov kub ntawm pyrolysis yog ntau dua li ntawm foaming, molding thiab ziab. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav tsis ua rau decomposition ntawm hais thiab theoretically yuav tsis tsim benzene monomer khib nyiab roj.
Nyob rau hauv qhov kev txiav txim ntawm squeezing quab yuam, me me ntawm cov molecules yuav tawg, decomposed, degraded, thiab lwm yam, thiab ib tug me me ntawm dawb monomer pov tseg roj tej zaum yuav generated. Yog li ntawd, yuav muaj tsawg heev ntawm cov dawb benzene monomers thiab qis boiling point additives thaum lub sij hawm foaming txheej txheem. Cov tshuaj tsis haum tshuaj yog tsim.
Nyob rau hauv cov txheej txheem ntawm foaming thiab molding, EPS yuav inevitably volatilize los tsim ib tug me me ntawm cov molecular hydrocarbon gas (feem ntau pentane) vim tshav kub.
