Ngā āhuatanga matū
He ātete te Polycarbonate ki te waikawa, te hinu, te hihi ultraviolet me te kawakore kaha.

Ngā āhuatanga ā-tinana
Ko te Polycarbonate he kore tae, he maamaa, he wera-wera, he paanga-atete, he mura-muri,
He pai nga ahuatanga miihini i roto i te pāmahana whakamahi noa.
Ka whakatauritea ki te polymethyl methacrylate he rite te mahi, he pai ake te parenga o te polycarbonate.
Ko te tohu tohu teitei, he pai te mahi tukatuka, UL94 V-2 te mahi mura ahi kaore he taapiri.
Heoi, he iti ake te utu o te polymethyl methacrylate,
A ka taea te whakaputa i nga taputapu nui-nui na roto i te polymerization nui.
Na te piki haere o te hanga o te polycarbonate,
Ko te rereketanga o te utu i waenga i te polycarbonate me te polymethyl methacrylate kei te whakaheke.
Ka wera te polycarbonate, ka puta te hau pyrolysis, ka wera te kirihou me te pahuka, engari kare e mau te ahi.
Ka tineia te mura i te wa e matara atu ana i te puna ahi, ka puta he kakara angiangi o te phenol, he kowhai te mura, he pango koma kanapa,
Ka tae te mahana ki te 140 ℃, ka timata ki te ngohe, ka rewa i te 220 ℃, ka taea e ia te mimiti i te awhi infrared.

He ngoikore te whakamarumaru o te polycarbonate.
Ko etahi o nga taputapu polycarbonate e whakamahia ana mo nga tono e mau ana me te whakamaarama motuhake.
