Polyamide (PA) izwi cyane nka nylon, kandi urunigi rurerure rwa karubone nylon bivuga ubwoko bwa nylon bufite amatsinda 10 cyangwa arenga ya methylene hagati yumubano wa amide uhuza urunigi runini rwa macromolecule, nka PA11, PA12, PA1010, PA1212, PA1012, nibindi .

Muri byo, PA610 na PA612 polyamide ebyiri ya alifatique, guhitamo diamine ndende ndende hamwe na hexamethylene diamine yegeranye, tuvuze rwose, ntabwo bihuye nibisobanuro byavuzwe haruguru, kubera uburebure bwa diacide irenga karubone 10, uburebure bwigihe cyigihe gito. ya kimwe cya kabiri ni ukuzuza ibisobanuro byurunigi rurerure rwa karubone nylon, mugihe uburebure bwa diamine karubone 6 gusa, bikavamo kurwanya ubushyuhe bwibintu hamwe nubukanishi nibindi bintu biruta urwego rurerure rwa karubone nylon, munsi gato ugereranije nintego rusange nylons PA6 na PA66, kubwibyo PA610 na PA612 bakunze gushyirwa mubikorwa nka nylon ndende ya karubone.

PA6 na PA66 bifite umuvuduko mwinshi wo kwinjiza amazi, bigatuma habaho itandukaniro ryinshi mubunini bwibicuruzwa nimiterere hamwe nubushyuhe bwo gutunganya cyane.Inzira ndende ya karubone nylons irashobora gukemura ikibazo cyo kubura iminyururu ngufi ya karubone kubera ibice birebire bya methylene hagati y amatsinda yegeranye.Usibye ibintu by'ibanze bya polyamide, binagaragaza ubucucike buke ugereranije, kwinjiza amazi make, guhagarara neza, kurwanya imiti myiza, kurwanya amashanyarazi meza, kurwanya ruswa, kurwanya abrasion, gukomera, kurwanya umunaniro no kurwanya ubushyuhe buke.
