Polyamide (e taʻua o le PA poʻo le Nylon) o tuʻutuʻuga lautele o resin thermoplastic, o loʻo iai le faʻateleina o vaega amide i luga ole filifili autu o molelaa. PA aofia ai aliphatic PA, aliphatic - aromatic PA ma aromatic PA, lea aliphatic PA, e maua mai i le numera o carbon atoms i le synthetic monomer, e tele ituaiga, o le sili gafatia ma le lautele faʻaoga.
Faatasi ai ma le miniaturization o taʻavale, o le maualuga faʻatinoina o mea faaeletonika ma eletise, ma le faʻavaveina o le mama auala o masini masini, o le manaʻoga mo nylon o le a maualuga ma sili atu. O le Nylon o loʻo i ai ni faʻaletonu e taua tele foi faʻatapulaʻaina lona faʻaogaina, aemaise mo PA6 ma PA66, faʻatusatusa i ituaiga PA46, PA12, e i ai le malosi tau faʻamanuiaga, e ui o nisi o gaioiga e le mafai ona faʻamalieina manaʻoga o le atinaʻeina o fesoʻotaiga alamanuia.
O le mea lea, e manaʻomia le faʻaleleia atili o ni meatotino e ala i fesuiaʻiga mo se tulaga faʻapitoa talosaga e faʻalauteleina ai lona fanua talosaga. Ona o le uiga o le malosi polarity, PA maua hygroscopicity malosi ma le lelei mautu tulaga, ae mafai ona faaleleia e ala i le fesuiaiga.
Lalo mea faʻaopopo e mafai ona matua faʻaleleia le faʻatinoga ile PA:
