Phakathi kweenkqubo ezahlukeneyo zokubumba iiplastiki,ukubumba ngenaliti Le yeyona isetyenziswa kakhulu. Le ngcamango ibonisa ukuba ukubumba ngenaliti kuneengenelo zokusetyenziswa kwezinto ezinamandla, ukukwazi ukubumba iimveliso ezinezakhiwo ezintsonkothileyo ngexesha elinye, iimeko zenkqubo ezivuthiweyo, ukuchaneka kwemveliso ephezulu, kunye neendleko zokusetyenziswa eziphantsi. Ke ngoko, iimveliso ezibunjiweyo ngenaliti zibalwa ngokwenani leemveliso zeplastiki ngamanye amaxesha. Njengoko kusanda, iinkqubo ezinxulumene noko, izixhobo, ukubumba kunye neendlela zokulawula ukusetyenziswa nazo ziye zaphuhliswa ngokukhawuleza.
Iithermoplastics zizinto zeplastiki ezinokubunjwa zibe yimo ethile xa zifudunyezwa, kwaye zinamathele kwimo egqityiweyo emva kokuba zipholile. Ukuba zifudunyezwa kwakhona, zinokuthanjiswa kwaye zinyibilike, kwaye inxalenye yeplastiki enobume obuthile inokwenziwa kwakhona, kwaye inokumiswa ngokuphindaphindiweyo, nto leyo enokuguqulwa.
Ngenxa yokuba ii-thermoplastics zizinto ezinokufudunyezwa ngokuphindaphindiweyo kwaye zithambe kwaye zipholiswe kwaye ziqine, zinokuqiniswa ngokuphindaphindiweyo kwaye zenziwe ngokufudumeza nokunyibilika, ngoko ke inkunkuma ye-thermoplastics idla ngokuphinda isetyenziswe kwaye isetyenziswe kwakhona, ebizwa ngokuba "zizinto zesibini". Emva kokuncipha kweendawo ezibunjiweyo ngenaliti ibhekisa ekubeni xa iindawo ezibunjiweyo ngenaliti zibunjiwe, uthotho lweengcinezelo lwenzeka ngenxa yotshintsho lwangaphakathi lomzimba, lwekhemikhali, nolwemishini. Emva kokuba iindawo ezibunjiweyo ngenaliti zibunjiwe kwaye ziqine, kukho iingcinezelo eziseleyo. Emva kokuba iindawo ezibunjiweyo ngenaliti zisusiwe, ngenxa yeengcinezelo ezahlukeneyo eziseleyo, Kuya kubangela ukuba ubungakanani beendawo ezibunjiweyo ngenaliti bunciphe kwakhona.
Ngokwesiqhelo, inxalenye ebunjiweyo ngenaliti iyancipha kakhulu kwiiyure ezili-10 emva kokudilizwa, kwaye ngokusisiseko ibunjwe emva kweeyure ezingama-24, kodwa kuthatha ixesha elide ukufikelela kwimo yokugqibela. Ngokubanzi, ukushwabana emva kokushwabana kwe-thermoplastics kukhulu kunokweplastiki ye-thermoset, kwaye ukushwabana emva kokushwabana kwenxalenye ebunjiweyo ngenaliti kunye nenxalenye ebunjiweyo ngenaliti kukhulu kunokwenxalenye ebunjiweyo ngenaliti encitshisiweyo.
