I-Polycarbonate (PC) kunye ne-Tritan™ zizinto ezimbini eziqhelekileyo zeplastiki ezingaweli ngokungqongqo phantsi koPhawu 7. Ngokuqhelekileyo azihlelwa ngokuthe ngqo njenge "7" kwinombolo yesazisi sokurisayikilisha ngenxa yokuba zineempawu ezizodwa kunye nokusetyenziswa.
I-PC (i-polycarbonate) yiplastiki enokucaca okuphezulu, ukumelana nobushushu obuphezulu kunye namandla aphezulu.Ihlala isetyenziselwa ukwenza iinxalenye zemoto, iiglasi zokukhusela, iibhotile zeplastiki, iikomityi zamanzi kunye nezinye iimpahla ezihlala ixesha elide.
I-Tritan™ sisixhobo esikhethekileyo se-copolyester esineempawu ezifana ne-PC, kodwa yenzelwe ukuba ibe yi-BPA (bisphenol A) simahla, ngoko ke ixhaphake kakhulu ekwenzeni iimveliso zoqhagamshelwano lokutya, ezinje ngeebhotile zokusela, izikhongozeli zokutya ziyalinda.I-Tritan™ isoloko ikhuthazwa njengengenayo ityhefu kwaye imelana nobushushu obuphezulu kunye neempembelelo.
Nangona ezi mathiriyeli zingahlelwanga ngokuthe ngqo phantsi kwe “No.7″ ukutyunjwa, kwezinye iimeko ezi zixhobo zinokubandakanywa kunye nezinye iiplastiki okanye imixube ngaphakathi kwe "No.7″ udidi.Oku kusenokuba ngenxa yokuntsonkotha kwazo okanye ngenxa yokuba kunzima ukucalula ngokungqongqo kwinombolo ethile yokuzazisa.
Kubalulekile ukuqaphela ukuba xa uhlaziywa kwaye ulahla ezi mathiriyeli zeplastiki zikhethekileyo, kungcono udibane nesixhobo sakho sasekhaya sokurisayikilisha okanye ii-arhente ezinxulumeneyo ukuqonda iindlela zokulahla ezichanekileyo kunye nokuba nokwenzeka.
