Polyamide (nanone yitwa PA cyangwa Nylon) nijambo rusange rya resmoplastique resin, irimo amide yisubiramo kumurongo munini wa molekile. PA ikubiyemo alifatique PA, alifatique - impumuro nziza PA na aromatic PA, aho alifatique PA, ikomoka ku mubare wa atome ya karubone muri monomer syntique, ifite ubwoko bwinshi, ubushobozi bwinshi kandi bukoreshwa cyane.
Hamwe na miniaturizasi yimodoka, imikorere myinshi yibikoresho bya elegitoroniki n’amashanyarazi, hamwe no kwihutisha inzira yoroheje y’ibikoresho bya mashini, icyifuzo cya nylon kizaba kinini kandi kinini. Inenge ya Nylon nayo ni ikintu cyingenzi kigabanya imikoreshereze yacyo, cyane cyane kuri PA6 na PA66, ugereranije nubwoko bwa PA46, PA12, bifite inyungu zikomeye, nubwo imikorere imwe idashobora kuzuza ibisabwa byiterambere ryinganda zijyanye nayo.
