Talu ona latou mauaina i le 1941, o meatotino o polyester polymers ua faʻamautu lelei i le alava, afifiina ma fausaga palasitika alamanuia, faʻafetai i lo latou maualuga faʻatinoina. PET e gaosia mai maualuga-faʻamatalaga crystallisable polymers thermoplastic. O le polymer o loʻo i ai le tele numera o meatotino fetaui i le gaosiga o vave mouldable, vevela-teteʻe maualuga-tonu vaega ma maualuga-tulaga faʻatau oloa. E maua le PET i vasega manino ma lanu.

Lelei
Faʻatasi ai ma le faʻapitoa tulaga lelei o PET, taʻutaʻu mafai ona faia o sili lelei aʻafiaga faapalepale ma maʻaʻaʻa. Anapogi vave taamilosaga taamilosaga taimi
ma lelei loloto-tusia ata ma e oʻo lava mafiafia pa. Leai se faamagoina o ipu i luma o suia. Lautele ituaiga o faʻaoga (-40 ° i le 65 °). Mafai ona malulu-faia e punou. Lelei tele tetee atu i vailaʻau, solvents, faamamaina sooupu, suauʻu ma gaʻo ma isi Maualuga teteʻe i faʻafitauli taʻe ma faʻapipiʻi. PET o loʻo i ai le tele o faʻapisinisi lelei. O le puʻupuʻu o le taimi e mautinoa ai le maualuga o le fua o le faʻagaioiga o galuega. Aesthetically matagofie: maualuga gloss, maualuga transparency poʻo le tutusa o lanu ma e faigofie ona lolomi pe teuteuina e aunoa ma muamua-togafitiga. Televave faʻatinoga faatinoga ma atoatoa toe faʻaleleia.
 
Faʻaogaina Talu ona faʻalauiloa mai luga o le maketi, ua lelei iloiloina PET i ituaiga eseese o talosaga e pei o fale tumama (tapu taele, potu taele), fefaatauaiga faʻatau, taʻavale (e faʻatali foʻi ni taʻavale), kiosks telefoni, pasi malulu ma isi mea e talafeagai ai PET mo meaʻai. ma fomaʻi apalai ma mo gamma-radiation faʻamamaina.

E i ai lua autu ituaiga o PET: Amorphous PET (APET) ma crystalline PET (CPET), o le sili ese taua eseesega o le CPET o se vaega crystallized, ao APET o amorphous. Faʻafetai i lona vaega crystalline fausaga CPET o opaque, ao APET i ai se amorphous fausaga, tuuina atu ia i ai se malamalama manino.
