NOMEX® uye KEVLAR® inonhuhwirira polyamides kana ma aramids akagadzirwa neDuPont.Izwi rekuti aramid rinobva paizwi rekuti anonhuwirira uye amide (aromatic + amide), inova polima ine akawanda amide zvisungo zvinodzokorora mupolymer cheni.Naizvozvo, yakakamurwa mukati meboka repolyamide.
Iyo ine inokwana 85% yeamide zvisungo zvakabatanidzwa neinonhuhwirira zvindori.Kune marudzi maviri makuru emaaramidhi, akaiswa muchikamu semeta-aramid, uye para-aramid uye rimwe nerimwe remapoka maviri aya rine zvimiro zvakasiyana zvine chekuita nezvimiro zvavo.
