I-Polycarbonate (i-PC) yisigaba se-polyester se-carbonic acid, i-carbonic acid ngokwayo ayizinzile, kodwa okuphuma kuyo (njenge-phosgene, urea, carbonate, carbonate) inokuqina okuthile.

Ngokwesakhiwo esihlukile sotshwala, i-polycarbonate ingahlukaniswa izigaba ezimbili ze-aliphatic nephunga elimnandi.

I-Aliphatic polycarbonate. Okufana ne-polyethylene-carbonate, i-polytrimethylene carbonate nama-copolymers ayo, indawo encibilikayo ephansi kanye nezinga lokushisa lokushintsha kwengilazi, amandla ampofu, angeke asetshenziswe njengezinto zokwakha; kodwa ukusetshenziswa kwe-biocompatibility yayo kanye nezakhiwo ezibolayo, zingasetshenziswa ezithwali zokukhululwa kancane kwezidakamizwa, ama-sutures okuhlinzwa, izinto zokusekela amathambo nezinye izinhlelo zokusebenza.

I-Polycarbonate imelana nama-asidi abuthakathaka, izisekelo ezibuthakathaka, namafutha angathathi hlangothi.

I-Polycarbonate ayimelani nokukhanya kwe-ultraviolet nama-alkali aqinile.

I-PC iwumugqa we-carbonate polyester enamaqembu e-carbonic acid ku-molecule namanye amaqembu angaba nephunga elimnandi, aliphatic, noma womabili. I-PC yohlobo lwe-Bisphenol A ingumkhiqizo wezimboni obaluleke kakhulu.

I-PC icishe ingabi nambala i-amorphous polymer eyingilazi enezici ezinhle zokubona. I-PC high molecular weight resin inokuqina okuphezulu, i-cantilever beam notched power impact of 600~900J/m, izinga lokushisa elingagcwalisiwe lezinga lokushisa elingagcwalisiwe elingaba ngu-130°C, i-glass fibre eqinisiwe ingenza leli nani lenyuke ngo-10°C. I-PC egoba i-modulus ingafinyelela ngaphezu kwe-2400MPa, i-resin ingacutshungulwa ibe yimikhiqizo emikhulu eqinile. Izinga lokungena ngaphansi komthwalo liphansi kakhulu ngaphansi kuka-100°C. I-PC imelana kabi ne-hydrolysis futhi ayikwazi ukusetshenziselwa imikhiqizo engaphansi kwengcindezi ephezulu kaningi.

Ukushiyeka okuyinhloko kokusebenza kwe-PC ukuntuleka kwayo kokuzinza kwe-hydrolytic, ukuzwela ukuchopha, ukumelana namakhemikhali emvelo, ukumelana kabi nokuklwebheka, kanye nokubaphuzi ngenxa yokuchayeka isikhathi eside ekukhanyeni kwe-UV. Njengamanye ama-resin, i-PC isengozini yokuguguleka yizincibilikisi ezithile eziphilayo.

Izisetshenziswa ze-PC zinolaka. Imelana ne-oxidation.
