Haunga te PVC, ka hangaia hoki e mātou he kāri polycarbonate (PC) me te Polyethylene Terephthalate Glycol (PETG). Nā ēnei rauemi kirihou e rua ka tino ātete ngā kāri ki te wera.

Nā, he aha te PETG, ā, he aha koe me whakaaro ai mō āu kāri kirihou? He mea whakamīharo, he mea hanga te PETG mai i te polyester (kia tika, he thermoplastic copolyester) ehara i te PVC, ā, he 100 ōrau te hangarua me te pirau. Heoi anō, he rite tonu tana mahi ki te PVC, nō reira he tino pakari, ā, he ātete ki te pānga. He ngāwari te tā ki te PETG, ā, he ātaahua te āhua o ngā hoahoa! Tirohia te ātaahua o ngā hoahoa ki te PETG.

Nō reira, he pai ngā kāri PC me te PETG mō ngā rohe wera, hei tauira ko te United Arab Emirates, ko Amerika ki te Tonga rānei, ina piki te pāmahana i te raumati ki te 40 nekehanga Celsius, tae atu ki te 65 nekehanga Celsius i roto i ngā motuka. Ka tīmata te rewa o te PVC i te 60 nekehanga.

He ātete wera ā mātou kāri PC me PETG tae atu ki te 120 nekehanga Celsius. Ko te tikanga, i roto i ētahi āhuatanga huarere kino, ka taea te waiho i tētahi kāri tuakiri mana i roto i te motuka i te wā tina me te kore e manukanuka, ā, kāore e hiahiatia kia whakawāteahia te mīhini kāri i roto i te pāka motuka o Toronto tae noa ki te ahiahi. He tino pakari hoki ēnei kāri, nō reira ka taea te whakamahi mō te tekau tau.

Ka whakapau kaha mātou ki te whakatutuki i ngā hiahia o ā mātou kiritaki mā te whakawhanake tonu, te hanga me te tuku hua auaha me te kounga teitei.
