Nalalka ugu badan ee loo isticmaalo wax soo saarka burushka warshadaha waa inay noqdaan naylon bristles, qaybta ugu muhiimsan ee naylon bristles waa polyamide (Nylon), magaca Ingiriisiga Polyamide (PA ee gaaban), waa erey guud oo loogu talagalay resins thermoplastic oo ay ku jiraan kooxaha amide soo noqnoqda - [NHCO ] - on silsiladda ugu weyn ee molecule.Waxaa ka mid ah aliphatic PA, aliphatic-aromatic PA iyo aromatic PA, kuwaas oo ay jiraan noocyo badan oo kala duwan, mugga wax soo saarka waaweyn iyo tiro balaadhan oo ah codsiyada, iyo magaceeda waxaa lagu go'aamiyaa tirada gaarka ah ee atamka carbon ee monomer synthetic.

Noocyada ugu waaweyn ee naylon waa naylon 6 iyo naylon 66, kuwaas oo gabi ahaanba awood leh.Waxaa jira tiro badan oo noocyo nayloon ah oo wax laga beddelay, sida naylon la xoojiyay, naylon monomer cast naylon (MC naylon), duritaanka fal-celinta (RIM) naylon, naylon caraf udgoon, naylon hufan, saameyn sare (super adag) naylon, naylon koronto ah, koronto ahaan naylon conductive, nylon olol retardant, nylon isku daraa polymers kale iyo Alloys, iwm si ay ula kulmaan kala duwan Waxaa si weyn loo isticmaalaa sida beddelka alaabta dhaqanka sida biraha iyo alwaax, iyo sida qalabka dhismaha ee dhammaan noocyada.

Naylon waa caaga injineerinka ugu muhiimsan, oo leh mugga wax soo saarka ugu sarreeya ee shanta caag ee injineerinka guud ee ugu sarreeya.Naylon waxa uu leeyahay xoog farsamo sare leh, dhibic jilciya sare, iska caabin kulaylka, coefficient hoose ee khilaaf, caabbinta abrasion, is-lubricating, shoogga nuugista iyo qoyaan dhawaaqa, caabbinta saliidda, caabbinta acid daciif ah, caabin alkali iyo caabbinta dareeraha guud, dahaarka koronto wanaagsan, nafta -daminta, aan sunta ahayn, ur la'aan, cimiladu u adkeysan karto iyo midab xumo.Khasaaraha ayaa ah in nuugista biyuhu ay weyn yihiin, taas oo saameynaysa xasilloonida cabbirka iyo sifooyinka korantada.Xoojinta fiberku waxay yarayn kartaa nuugista biyaha ee xabagta si ay ugu shaqeyso heerkul sare iyo qoyaan badan.Naylon waxay leedahay xiriir aad u wanaagsan oo leh fibre-dharado.

Nylon 66 ayaa leh qallafsanaanta ugu sareysa iyo qallafsanaanta, laakiin ugu daran.Nayloonyo kala duwan ayaa lagu dalbadaa adag: PA66 ~ PA66/6 PA6＜PA610＜PA6＜PA610＜PA11＜PA12 Gubashada naylon waa heerka UL94v-2, tusaha oksijiinta waa 24-28, heerkulka kala go'a ee naylon waa> 299 ℃, iyo si kedis ah gubashada waxay ka dhici doontaa 449 ~ 499 ℃.Qulqulka dhalaalka naylon waa wanaagsan yahay, markaa dhumucda gidaarka alaabtu waxay noqon kartaa mid yar ilaa 1mm.
