Na Waiwai Kemika:

Polycarbonatehe amorphous, ʻono ʻole, ʻala ʻole, non-toxic transparent thermoplastic polymer, he mechanical maikaʻi loa, wela a me nā waiwai uila, ʻoi aku ka hopena o ka hopena, paʻakikī maikaʻi, liʻiliʻi ke kolo, paʻa ka nui o ka huahana. ʻO ka ikaika o ka hopena o 44kj / mz, ka ikaika tensile> 60MPa. He maikaʻi ka pale ʻana o ka wela polycarbonate, hiki ke hoʻohana ʻia no ka manawa lōʻihi ma - 60 ~ 120 ℃, wela wela deflection 130 ~ 140 ℃, aniani hoʻololi wela o 145 ~ 150 ℃, ʻaʻohe wahi heheʻe ʻike, ma 220 ~ 230 ℃ ke kūlana hoʻoheheʻe. . ʻO ka wela wela o ka decomposition > 310 ℃. Ma muli o ka rigidity o ke kaulahao mole, ʻoi aku ka kiʻekiʻe o kona viscosity hehee ma mua o nā thermoplastics maʻamau.

Noi:

ʻO nā polycarbonates nā plastics i hoʻohana nui ʻia i ka ʻoihana hou me ka maikaʻi o ka mahana a me ke kūpaʻa hopena. Maikaʻi loa kēia plastic e hana me nā ʻenehana wehewehe maʻamau (hoʻoheheʻe injection, extrusion i loko o nā paipu a i ʻole nā ​​cylinders a me ka thermoforming). Hoʻohana pū ʻia ia i ka wā e pono ai ka ʻike maka, me ka hoʻouna ʻana ma mua o 80% a hiki i ka laulā 1560-nm (nā nalu pōkole infrared). Loaʻa iā ia nā waiwai kūʻē kemika, ʻo ia ke kū kūʻē i nā ʻakika diluted a me nā waiʻona. ʻAʻole maikaʻi ke kūʻē i nā ketones, halogens, a me nā waikawa concentrated. ʻO ka pōʻino nui e pili ana i ka polycarbonates ʻo ia ke aniani hoʻololi haʻahaʻa haʻahaʻa (Tg> 40 ° C), akā hoʻohana nui ʻia ʻo ia ma ke ʻano he kumu kūʻai haʻahaʻa i nā ʻōnaehana microfluidic a ma ke ʻano he ʻāpana mōhai.
