E bonolo ho qhalanya le ho kopanya, e ka kopanngoa hantle le li-substrate tsa polasetiki ntle le ho ama lits'ebetso tsa ho bopa (ho enta ka ente, ho ntša, ho bopa ka ho phatloha, jj.), le ntle le ho fetola 'mala oa pele, boima, kapa ho tiea ha polasetiki. E loketse litlhoko tsohle tsa tlhahiso tse kang liphaephe, lipoleiti, lifilimi, likarolo tsa likoloi, thepa ea kaho ea kantle le thepa ea ho paka.
2. Khanyetso ea Mocheso o Phahameng le Khahlanong le ho Falla, Ho netefatsa Tšireletso e sa Hlōleheng
Botsitso bo botle ba mocheso (mocheso oa ho bola > 300°C), bo khona ho mamella mekhoa ea ho sebetsana le polasetiki mochesong o phahameng; ha ho bonolo ho e falla kapa ho e pompa, bo boloka litlamorao tse tsitsitseng tsa tšireletso nakong ea tšebeliso ea nako e telele, le ho qoba ho petsoha le ho lahla lihlahisoa mohatong oa morao.
