Nā waiwai kemika
Kū'ē ka Polycarbonate i nā waikawa, nā aila, nā kukui ultraviolet a me nā alkali ikaika.

Nā waiwai kino
ʻO ka polycarbonate he kala ʻole a ʻaʻole maopopo, pale wela, pale i ka hopena, pale ahi,
Loaʻa iā ia nā waiwai mechanical maikaʻi i ka mahana hoʻohana maʻamau.
Hoʻohālikelike ʻia me ka polymethyl methacrylate me ka hana like, ʻoi aku ka maikaʻi o ka hopena o ka polycarbonate.
Kiʻekiʻe refractive index, maikaʻi hana hana, UL94 V-2 flame retardant hana me ka ʻole o nā mea hoʻohui.
Eia naʻe, emi ke kumu kūʻai o ka polymethyl methacrylate,
A hiki ke hana i nā mea hana nui ma o ka polymerization nui.
Me ka hoʻonui nui ʻana o ka polycarbonate,
Ke emi nei ke kumu kūʻai ma waena o ka polycarbonate a me ka polymethyl methacrylate.
Ke ʻā ka polycarbonate, hoʻopuka ia i ke kinoea pyrolysis, a ʻā a ʻā ka palaka, akā ʻaʻole ia e puhi i ke ahi.
Ua pio ka lapalapa i ka wā e kaʻawale ai i ke kumu ahi, e hoʻopuka ana i kahi ʻala lahilahi o ka phenol, melemele ka lapalapa, ʻeleʻele ʻālohilohi.
Hiki i ka mahana ke 140 ℃, hoʻomaka ia e palupalu, a hoʻoheheʻe i 220 ℃, hiki ke hoʻomoʻa i ka spectrum infrared.

ʻAʻole maikaʻi ka pale ʻana o ka polycarbonate.
ʻO kekahi mau mea polycarbonate i hoʻohana ʻia no ka hoʻohana ʻana i ka lole e pono ai ka mālama ʻana i ka ʻili kūikawā.
