Acrylonitrile butadiene styrene (ABS) (tsarin sinadarai (C8H8)x·(C4H6)y·(C3H3N)z) polymer thermoplastic na kowa.Matsakaicin canjin gilashin sa yana da kusan 105 ° C (221 ° F).ABS ne amorphous sabili da haka ba shi da gaskiya na narkewa batu.Polytetrafluoroethylene (PTFE) wani roba fluoropolymer na tetrafluoroethylene cewa yana da yawa aikace-aikace.Mafi sanannun sunan alamar ƙirar PTFE shine polymer ta Chemours.Chemours wani yanki ne na DuPont Co., wanda ya gano fili a cikin 1938.
Mafi mahimmancin kayan aikin injiniya na ABS shine juriya da tasiri.Ana iya yin gyare-gyare iri-iri don inganta juriya mai tasiri, ƙarfi, da juriya na zafi.Za'a iya haɓaka juriya na tasiri ta hanyar ƙara yawan adadin polybutadiene dangane da styrene da kuma acrylonitrile, kodayake wannan yana haifar da canje-canje a wasu kaddarorin.Juriyar tasiri baya faɗuwa da sauri a ƙananan yanayin zafi.Ƙarfafawa a ƙarƙashin kaya yana da kyau tare da iyakataccen nauyi.Don haka, ta hanyar canza ma'auni na abubuwan da aka haɗa, ABS za a iya shirya shi a matakai daban-daban.Manyan nau'ikan nau'ikan guda biyu na iya zama ABS don extrusion da ABS don gyare-gyaren allura, sannan juriya mai tsayi da matsakaici.Gabaɗaya ABS zai sami halaye masu amfani a cikin kewayon zafin jiki daga -20 zuwa 80 °C (-4 zuwa 176 °F).
PTFE shine polymer thermoplastic, wanda yake shi ne fari mai ƙarfi a cikin zafin jiki, tare da nauyin kusan 2200 kg/m3.A cewar DuPont, wurin narkewar sa shine 600 K (327 ° C; 620 ° F).Yana kiyaye babban ƙarfi, tauri da lubrication kai a ƙananan yanayin zafi zuwa 5 K (-268.15 ° C; -450.67 °F), da kuma sassauci mai kyau a yanayin zafi sama da 194 K (-79 °C; -110 °F).PTFE yana samun kaddarorin sa daga jimillar tasirin carbon-fluorine bond, kamar yadda duk fluorocarbons ke yi.Abubuwan sinadarai guda ɗaya da aka sani suna shafar waɗannan haɗin gwiwar carbon-fluorine sune karafa masu amsawa sosai kamar ƙarfe na alkali, kuma a yanayin zafi mai girma haka kuma irin su aluminum da magnesium, da abubuwan da ke haifar da fluorine kamar xenon difluoride da cobalt (III) fluoride.
