Kugirango ugabanye ibiciro byibicuruzwa no kubona imikorere yinyongera,Polyurethane thermoplastiqueElastomers irashobora gukoreshwa nkibisanzwe byakoreshejwe abakozi ba toughening kugirango bavuze ibikoresho bitandukanye bya thermoplastique no guhindura ibikoresho bya rubber.
KuberaPolyurethaneKuba polymer polymer cyane, birashobora guhuza ibisohokamo cyangwa reberi, nko mugihe bikoreshwa hamwe na chlorinated polloyethlene (cpe) kugirango itange ibicuruzwa byubuvuzi; Kuvanga ab irashobora gusimbuza ikoreshwa rya plastiki yubuhanga; Iyo bikoreshejwe hamwe na Polycarbonate (PC), ifite imitungo nko kurwanya peteroli, kurwanya lisansi, no kurwanya amavuta, no kurwanya ingaruka, kandi birashobora gukoreshwa mugukora imibiri yimodoka; Kuvanga na polyester birashobora kunoza imikorere yacyo; Byongeye kandi, birashobora guhuza neza na chloride ya chloride, polyoxymethylene (pom), cyangwa polyvinylidene chloride; Polyester Polyurethane irashobora guhuza neza na 15% nitrile reberi cyangwa 40% nitrile rubber / polyvinyl chloride avanze reberi; Polyethethane nayo irashobora guhuza neza na 40% nitrile reberi / polyvinyl chloride kuvanga; Irashobora kandi kubana na Acrylonitrile Styrene (San) copolymers; Irashobora gukora umuyoboro utabara (IPN) hamwe na Polysiloxanes. Umubare munini wibintu byavuzwe haruguru bivugururwa byavuzwe haruguru bimaze kubyara kumugaragaro.
Mu myaka yashize, habaye ubwitonzi bwubushakashatsi ku muyoboro wa pomTPUmu Bushinwa. Guhuza TPU na pom ntibizamura gusa kurwanya ubushyuhe bukabije hamwe nubutaka bwa TPU, ariko kandi buke cyane pom. Abashakashatsi bamwe bagaragaje ko mu bizamini bya tenile, ugereranije na pom matrix, pom alloys hamwe no kongeramo inzitizi ziva mu kuvunika ubwato kugeza ku nkombe. Ongeraho TPU nayo irangiza POM hamwe n'imikorere yibuka. Agace ka Crystalline wa Pom ikingira nk'icyiciro cyagenwe cyo kwibuka Asloy, mu gihe akarere ka amorhous TPU na Pom bikora nk'icyiciro gihamye. Iyo ubushyuhe bwo kugarura ari 165 ℃ kandi igihe cyo gukira ni 120 s, igipimo cyo gukira cya aly nacyo kigera kuri 95%, kandi ingaruka zo gukira nibyiza.
TPU biragoye guhuza ibikoresho bya polymer bidafite polymer nka polyethylene, polypropylene, Butadiene Rubber, Butadiene Rubber, Butadiene Rubber, Burdene Kubwibyo, uburyo bwo kuvura hejuru nka plasma, gusohora corona, chirotsi itose, primer, urumuri, urumuri, cyangwa imyuka ishakisha akenshi ikoreshwa kubwanyuma. Kurugero, ibigo byabanyamerika byo mu kirere hamwe nibigo bya shimi bishobora kunoza imbaraga zo kunyeganyega, imbaraga zidasanzwe, kandi wambare uburemere bwa ulstarylene ifu nziza hamwe nuburemere bwa gaze ya miliyoni 35 nyuma ya sulsinethane. Byongeye kandi, F2 / O2 ubuvuzi bwuzuye bukomeye burashobora gukoreshwa kuri fibre ngufi ya 6-35mm yavuzwe haruguru, ishobora kunoza gukomera no gutoza ibintu bisanzwe.
