Ha ho nahanoa ka tšebeliso, ke habohlokoa ho hopola lipotso tse latelang:
Karolo e tla sebelisoa hokae?

Thermoplastics ke khetho e ratoang bakeng sa ho bopa ente. Ka mabaka a mangata a kang ho sebelisoa hape habonolo le boiketlo ba ho sebetsa. Kahoo moo sehlahisoa se ka etsoang ka ente ho sebelisa thermoplastic, e-ea bakeng sa seo. Lihlahisoa tse phahameng tse feto-fetohang ka nako e telele li bakile tlhoko ea li-elastomer tsa thermoset. Kajeno o na le khetho ea thermoplastic elastomers. E le hore karolo ea hau e hloke ho tenyetseha haholo ha e tlose khetho ea ho sebelisa thermoplastics. Ho boetse ho na le limaraka tse fapaneng tsa li-TPE ho tloha ho boemo ba lijo ho isa ho li-TPE tse sebetsang hantle haholo.
Li-plastiki tsa thepa li sebelisoa lihlahisoa tsa letsatsi le letsatsi tsa bareki. Mehlala ke likopi tsa kofi ea polystyrene, likotlolo tsa ho nka polypropylene, le likatiba tsa botlolo tsa polyethylene tse bopehileng haholo. Li theko e tlaase ebile li fumaneha haholoanyane. Lipolasetiki tsa boenjiniere li sebelisoa, joalo ka ha lebitso le bolela, lits'ebetso tsa boenjiniere. U tla li fumana ka li-greenhouses, lishiti tsa marulelo le lisebelisoa. Mehlala ke polyamides (Nylon), polycarbonate (PC), le acrylonitrile butadiene styrene (ABS). Li ka mamella maemo a thata haholoanyane a tikoloho. Li tla mamella mojaro le thempereichara hantle ka holimo ho mocheso oa kamore. Li-plastiki tse sebetsang hantle li sebetsa hantle tlas'a maemo ao lihlahisoa le li-plastiki tsa boenjiniere li hlōlehang.
