Polyamide (PA) imadziwika kuti nayiloni, ndipo nayiloni yayitali ya carbon nylon imatanthawuza mitundu ya nayiloni yokhala ndi magulu 10 kapena kuposerapo a methylene pakati pa zomangira zoyandikana za amide mu unyolo waukulu wa macromolecule, monga PA11, PA12, PA1010, PA1212, PA1012, ndi zina zambiri. .

Pakati pawo, PA610 ndi PA612 awiri aliphatic polyamides, kusankha diamines yaitali unyolo ndi hexamethylene diamine condensation, kunena mosapita m'mbali, sagwirizana ndi tanthauzo pamwamba, chifukwa cha kutalika kwa diacid kuposa 10 mpweya, nthawi yaitali mu imeneyi. theka ndi kukwaniritsa tanthauzo la nayiloni yaitali mpweya unyolo, pamene kutalika kwa diamine yekha 6 mpweya, chifukwa mu zinthu kutentha kukana ndi katundu makina ndi katundu wina kuposa yaitali mpweya nayiloni unyolo, pang`ono m`munsi kuposa The ambiri Cholinga nayiloni PA6 ndi PA66, motero PA610 ndi PA612 nthawi zambiri amagawidwa ngati ma nayiloni aatali a carbon.

PA6 ndi PA66 ali ndi kuchuluka kwa mayamwidwe amadzi, zomwe zimapangitsa kuti pakhale kusiyanasiyana kwakukulu pakukula kwazinthu ndi katundu komanso kutentha kwambiri.Nayiloni zazitali za carbon chain zingapangitse kuchepa kwa unyolo waufupi wa carbon chifukwa cha zigawo zazitali za methylene pakati pa magulu oyandikana nawo amide.Kuphatikiza pa zinthu zoyambira za ma polyamides, amakhalanso ndi kachulukidwe kakang'ono, kuyamwa kwamadzi otsika, kukhazikika kwamphamvu, kukana kwamphamvu kwamankhwala, mphamvu zamagetsi zamagetsi, kukana dzimbiri, kukana kwa abrasion, kulimba, kukana kutopa komanso kukana kutentha kwambiri.
