Plasticity yog cov cuab yeej ntawm tag nrho cov ntaub ntawv uas tau hloov irreversibly tsis txhawm tab sis, nyob rau hauv cov chav kawm ntawm moldable polymers, qhov no tshwm sim rau xws li ib cov degree uas lawv tiag tiag lub npe los ntawm no tshwj xeeb muaj peev xwm.
Plastics yog feem ntau cov organic polymers ntawm cov khoom loj molecular thiab feem ntau muaj lwm yam tshuaj. Lawv feem ntau yog hluavtaws, feem ntau feem ntau los ntawm petrochemicals, li cas los xij, ib qho array ntawm variants yog ua los ntawm cov ntaub ntawv tauj dua tshiab xws li polylactic acid ntawm pob kws los yog cellulosics ntawm paj rwb.
Vim lawv pheej yig cov nqi, yooj yim ntawm kev siv ua, ntau yam, thiab tsis sib haum rau dej, cov khoom siv hauv ntau ntau cov khoom sib txawv, nrog rau cov ntawv txiav thiab kos duab huab cua. Lawv tau hla ntau cov ntaub ntawv, xws li ntoo, pob zeb, kub thiab pob txha, tawv, hlau, iav, thiab tej hub, hauv qee yam khoom uas twb dhau mus rau cov ntaub ntawv uas ntuj.
