Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z) ke polymer e tloaelehileng ea thermoplastic.Thempereichara ea phetoho ea khalase ea eona e ka ba 105 °C (221 °F).ABS ke amorphous mme ka hona ha e na ntlha ea 'nete ea ho qhibiliha.Polytetrafluoroethylene (PTFE) is an synthetic fluoropolymer of tetrafluoroethylene that has many applications.Lebitso la lebitso le tsebahalang haholo la liforomo tse thehiloeng ho PTFE ke polymer by Chemours.Chemours ke sekheo sa DuPont Co., se sibolotseng komporo ka 1938.
Mehaho ea bohlokoa ka ho fetisisa ea mochini oa ABS ke ho hanyetsa tšusumetso le ho tiea.Liphetoho tse fapaneng li ka etsoa ho ntlafatsa ho hanyetsa tšusumetso, ho tiea le ho hanyetsa mocheso.Ho hanyetsa tšusumetso ho ka matlafatsoa ka ho eketsa likarolo tsa polybutadiene mabapi le styrene le acrylonitrile, le hoja sena se baka liphetoho linthong tse ling.Tšusumetso ea ho hanyetsa ha e theohe ka potlako mocheso o tlase.Botsitso tlas'a mojaro bo babatsehang ka meroalo e fokolang.Kahoo, ka ho fetola boholo ba likarolo tsa eona, ABS e ka lokisoa ka limaraka tse fapaneng.Mekhahlelo e 'meli e meholo e ka ba ABS bakeng sa extrusion le ABS bakeng sa ho bopa ente, ebe ho hanyetsa tšusumetso e phahameng le e mahareng.Ka kakaretso ABS e ka ba le litšobotsi tse molemo ka har'a mocheso o fapaneng ho tloha ho -20 ho ea ho 80 °C (−4 ho 176 °F).
PTFE ke polymer ea thermoplastic, e tiileng e tšoeu ka mocheso oa kamore, 'me boima ba eona bo ka ba 2200 kg/m3.Ho ea ka DuPont, sebaka sa eona se qhibilihang ke 600 K (327 °C; 620 °F).E boloka matla a phahameng, ho thatafala le ho itlotsa ha mocheso o tlase ho 5 K (−268.15 °C; -450.67 °F), le ho tenyetseha hantle ha mocheso o ka holimo ho 194 K (−79 °C; -110 °F).PTFE e fumana thepa ea eona ho tsoa litlamong tse kopaneng tsa carbon-fluorine bond, joalo ka li-fluorocarbons tsohle.Lik'hemik'hale feela tse tsejoang ka ho ama litlamo tsena tsa carbon-fluorine ke litšepe tse sebetsang haholo joalo ka tšepe ea alkali, 'me lithempereichara tse phahameng hape tse kang aluminium le magnesium, le lisebelisoa tsa fluorinating joalo ka xenon difluoride le cobalt(III) fluoride.
