Polycarbonates (PC) yog ib pawg ntawm cov thermoplastic polymers uas muaj carbonate pawg hauv lawv cov qauv tshuaj.Polycarbonates siv hauv engineering yog cov khoom muaj zog, cov ntaub ntawv tawv, thiab qee cov qib yog optically pob tshab.Lawv tau yooj yim ua haujlwm, molded, thiab thermoformed.Vim tias cov khoom no, polycarbonates pom ntau daim ntawv thov.Polycarbonates tsis muaj cov cim cim cim cim (RIC) thiab raug txheeb xyuas tias "Lwm yam", 7 ntawm RIC daim ntawv teev npe.Cov khoom tsim los ntawm polycarbonate tuaj yeem muaj cov precursor monomer bisphenol A (BPA).
PTFENws yog cov khoom siv fluorocarbon, vim nws yog cov khoom hnyav molecular uas muaj cov pa roj carbon thiab fluorine tag nrho.PTFE yog hydrophobic: tsis yog dej los yog dej-muaj tshuaj ntub dej PTFE, raws li fluorocarbons qhia mitigated London dispersion rog vim lub siab electronegativity ntawm fluorine.PTFE muaj ib qho qis tshaj coefficients ntawm kev sib txhuam ntawm cov khoom.
