I-Bisphenol A (BPA) iyikhemikhali esetshenziswa kakhulu ekukhiqizeni imikhiqizo yepulasitiki, njenge-PC (i-polycarbonate) namanye ama-epoxy resins.Kodwa-ke, njengoba ukukhathazeka ngezingozi zezempilo ezingaba khona ze-BPA kwanda, abanye abakhiqizi bemikhiqizo yepulasitiki sebeqalile ukubheka ezinye izindlela zokukhiqiza imikhiqizo engenayo i-BPA.Nazi ezinye izinto zepulasitiki ezijwayelekile ezivame ukukhangiswa njenge-BPA-free:
1. I-Tritan™:
I-Tritan™ iwumsebenzi wepulasitiki we-copolyester okhethekile omakethwa njenge-BPA-free kuyilapho unikeza ukukhanya okuphezulu, ukumelana nokushisa nokuqina.Ngenxa yalokho, impahla ye-Tritan™ isetshenziswa ezitsheni eziningi zokudla, izibuko zokuphuza, nezinye izimpahla ezihlala isikhathi eside.
2. PP (i-polypropylene):
I-Polypropylene ngokuvamile ithathwa njengepulasitiki engena-BPA futhi isetshenziswa kakhulu ezitsheni zokudla, amabhokisi okudla e-microwave neminye imikhiqizo yokuxhumana nokudla.
3. I-HDPE (i-polyethylene e-high density) ne-LDPE (i-polyethylene e-low density):
I-polyethylene (i-HDPE) ene-high-density polyethylene (LDPE) ngokuvamile ayinayo i-BPA futhi ijwayele ukusetshenziselwa ukwenza amafilimu okupakisha ukudla, izikhwama zepulasitiki, njll.
4. I-PET (i-polyethylene terephthalate):
I-Polyethylene terephthalate (PET) nayo ibhekwa njenge-BPA-free ngakho-ke isetshenziselwa ukukhiqiza amabhodlela esiphuzo acacile kanye nokupakishwa kokudla.
Kubalulekile ukuqaphela ukuthi nakuba lezi zinto zepulasitiki zivame ukukhangiswa njenge-BPA-free, kwezinye izimo ezinye izithasiselo noma amakhemikhali angase abe khona.Ngakho-ke, uma ukhathazeke kakhulu ngokugwema ukuchayeka ku-BPA, kungcono ukubheka imikhiqizo ephawulwe ngelogo ethi “BPA Free” bese uhlola ukupakishwa komkhiqizo noma izinto zokukhangisa ezihlobene ukuze uqinisekise.
