Acrylonitrile butadiene styrene (ABS) (qaaciido kiimikaad (C8H8) x·(C4H6)Heerkulka kala-guurka galaasku waa qiyaastii 105 °C (221 °F).ABS waa amorphous sidaas darteed ma laha meel dhalaalaysa oo run ah. Polytetrafluoroethylene (PTFE) waa fluoropolymer synthetic ee tetrafluoroethylene oo leh codsiyo badan.Magaca caanka ah ee ugu caansan qaababka PTFE-ku salaysan waa polymer by Chemours.Chemours waa wareegtada DuPont Co., kaas oo helay xarunta 1938-kii.
Astaamaha ugu muhiimsan ee farsamada ABS waa iska caabbinta saameynta iyo adkaanta.Wax ka beddello kala duwan ayaa la samayn karaa si loo hagaajiyo iska caabbinta saamaynta, adkaanta, iyo caabbinta kulaylka.Iska caabbinta saameynta waxaa lagu kordhin karaa iyada oo la kordhinayo saamiga polybutadiene ee la xidhiidha styrene iyo sidoo kale acrylonitrile, inkastoo tani ay keento isbeddelada guryaha kale.Iska caabbinta saameyntu si degdeg ah uguma dhacayso heerkulka hoose.Xasiloonida culeyska saaran waa mid aad u wanaagsan oo leh culeys xaddidan.Haddaba, iyadoo la beddelayo saamiga qaybaheeda, ABS waxaa lagu diyaarin karaa darajooyin kala duwan.Laba qaybood oo waaweyn ayaa noqon kara ABS oo loogu talagalay extrusion iyo ABS oo loogu talagalay qaabaynta duritaanka, ka dibna iska caabin sare iyo dhexdhexaad ah.Guud ahaan ABS waxay yeelan doontaa sifooyin waxtar leh oo u dhexeeya heerkulka u dhexeeya -20 ilaa 80 °C (-4 ilaa 176 °F).
PTFE waa polymer thermoplastic, kaas oo ah adag cad oo heerkulka qolka, leh cufnaanta qiyaastii 2200 kg/m3.Sida laga soo xigtay DuPont, barta dhalaalkeedu waa 600 K (327 ° C; 620 ° F).Waxay ilaalisaa xoog sare, adkeysi iyo is-saliid heerkul hooseeya ilaa 5 K (-268.15 °C; -450.67 °F), iyo dabacsanaan wanaagsan heerkulka ka sarreeya 194 K (-79 °C; -110 °F).PTFE waxay hantideeda ka heshaa saamaynta isku-darka ah ee curaarta kaarboon-fluorine, sida dhammaan fluorocarbons.Kiimikooyinka kaliya ee loo yaqaan inay saameeyaan curaarta carbon-fluorine waa biraha aadka u firfircoon sida biraha alkali, iyo heerkulka sare sidoo kale biraha sida aluminium iyo magnesium, iyo wakiilada fluorine sida xenon difluoride iyo kobalt (III) fluoride.
