Izinto ezibolayo yizinto ezingahlukaniswa ngokuphelele zibe ama-molecule aphansi yizinto ezincane (isb., amabhaktheriya, isikhunta, kanye nolwelwe, njll.) ngaphansi kwezimo zemvelo zemvelo zesikhathi esifanele nesibonakalayo. Njengamanje, zihlukaniswe kakhulu ngezigaba ezine eziyinhloko: i-polylactic acid (PLA), i-PBS, i-polylactic acid ester (PHA) kanye ne-polylactic acid ester (PBAT).
I-PLA inokuphepha kwezinto eziphilayo, ukubola kwezinto eziphilayo, izakhiwo ezinhle zemishini kanye nokucutshungulwa okulula, futhi isetshenziswa kabanzi ekupakisheni, ezindwangu, efilimini yepulasitiki yezolimo kanye nasezimbonini ze-polymer zezokwelapha.
I-PBS ingasetshenziswa efilimini yokupakisha, ezitsheni, ezintweni zokupakisha ze-foam, emabhodleleni asetshenziswa nsuku zonke, emabhodleleni emithi, emafilimini ezolimo, ezintweni zomanyolo wezibulala-zinambuzane ezikhipha kancane kanye neminye imikhakha.
I-PHA ingasetshenziswa emikhiqizweni elahlwayo, izingubo zokuhlinzwa zamadivayisi ezokwelapha, izikhwama zokupakisha nezokufaka umquba, izithungo zezokwelapha, amadivayisi okulungisa, amabhandeji, izinaliti zamathambo, amafilimu okulwa nokunamathela kanye nama-stents.
I-PBAT inezinzuzo zokusebenza kahle kokwenza ifilimu kanye nokufuthwa kwefilimu okulula, futhi isetshenziswa kabanzi emikhakheni yamafilimu okupakisha alahlwayo namafilimu ezolimo.
