Amapulasitiki adlala indima enqumayo ekuthuthukiseni ukuthuthukiswa komkhakha we-plastics, ikakhulukazi imboni ye-polyvinyl chloride . Lokhu okulandelayo kuyisifinyezo sezinto ezithinta amapulasitiki .
Okokuqala, izici ezithinta ipulasitiki (i-crude ester) Flash point the flash ephelele yesositiki se-dibasic acid ihlobene nesisindo se-molecular {{0} Uma isisindo se-molecular siphansi kakhulu, umphumela wepulasitiki uzoba mpofu futhi ngeke ube namandla .
Okwesibili, izici ezithinta ipulasitiki (i-Primary Ester) Inani le-acid elingavuthiwe kanye nama-monoesters (ama-acid acijile kanye nama-acid angenayo ngenxa yokwahlukanisa okuphezulu ngesikhathi senqubo efanayo, okuthinta inani le-acid lomkhiqizo ngezinga elifanayo .
