Kugirango ugabanye ibiciro byibicuruzwa no kubona imikorere yinyongera,polyurethaneelastomers irashobora gukoreshwa nkibisanzwe bikoreshwa mugukomera ibikoresho bitandukanye bya termoplastique kandi byahinduwe.
Kuberapolyurethanekuba polymer polymer cyane, irashobora guhuzwa na polar resin cyangwa reberi, nkigihe ikoreshwa ifatanije na chlorine polyethylene (CPE) kugirango ikore ibicuruzwa byubuvuzi;Kuvanga na ABS birashobora gusimbuza ikoreshwa rya plastike ya thermoplastique;Iyo ikoreshejwe ifatanije na polyakarubone (PC), ifite ibintu nko kurwanya amavuta, kurwanya lisansi, no kurwanya ingaruka, kandi irashobora gukoreshwa mugukora imibiri yimodoka;Kuvanga na polyester birashobora kunoza imikorere yayo;Byongeye kandi, irashobora guhuzwa neza na chloride polyvinyl, polyoxymethylene (POM), cyangwa chloride polyvinylidene;Polyester polyurethane irashobora guhuzwa neza na 15% ya nitrile reberi cyangwa 40% ya nitrile reberi / polyvinyl chloride ivanze;Polyetherthane irashobora kandi guhuzwa neza na 40% ya nitrile rubber / polyvinyl chloride ivanze;Irashobora kandi guhuzwa na acrylonitrile styrene (SAN) copolymers;Irashobora gukora imiyoboro ihuza imiyoboro (IPN) hamwe na polysiloxane ikora.Umubare munini wibintu byavuzwe haruguru bivanze bimaze gukorwa kumugaragaro.
Mu myaka yashize, habaye ubushakashatsi bwiyongera ku gukomera kwa POM naTPUmu Bushinwa.Kuvanga TPU na POM ntabwo bizamura gusa ubushyuhe bwo hejuru hamwe nubukanishi bwa TPU, ahubwo binashimangira cyane POM.Bamwe mu bashakashatsi berekanye ko mu bizamini byavunitse cyane, ugereranije na matrike ya POM, ibivangwa na POM hamwe na TPU byongeweho biva mu kuvunika kuvunika bikavunika.Kwiyongera kwa TPU kandi biha POM imikorere yibikorwa byo kwibuka.Agace ka kristalline ya POM ikora nkicyiciro gihamye cyimiterere yibikoresho byo kwibuka, mugihe akarere ka amorphous ya amorphous TPU na POM ikora nkicyiciro gisubira inyuma.Iyo ubushyuhe bwo gusubiza ubushyuhe ari 165 ℃ naho igihe cyo gukira ni 120 s, igipimo cyo gukira kivanze kigeze hejuru ya 95%, kandi ingaruka zo gukira nibyiza.
TPU iragoye guhuzwa nibikoresho bidafite polimeri nka polyethylene, polypropilene, rubber etylene propylene, butadiene reberi, isoprene reberi, cyangwa ifu ya rubber, kandi ntishobora kubyara ibikoresho bifatika hamwe nibikorwa byiza.Kubwibyo, uburyo bwo kuvura hejuru nka plasma, corona isohoka, chimie itose, primer, flame, cyangwa gaze reaction ikoreshwa kenshi kubwa nyuma.Kurugero, ibicuruzwa byindege byabanyamerika hamwe namasosiyete yimiti birashobora kunoza cyane modulus yunamye, imbaraga zingana, no kwambara birwanya imbaraga za ultra-high molekulari polyethylene ifu nziza ifite uburemere bwa miriyoni 3-5 nyuma yo gutunganya gazi ya F2 / O2, kandi kuyongera kuri polyurethane elastomers mukigereranyo cya 10%.Byongeye kandi, F2 / O2 itunganya gazi isanzwe irashobora gukoreshwa kuri fibre ngufi irambuye ifite uburebure bwa 6-35mm yavuzwe haruguru, ishobora kunoza ubukana no kurira bikabije.
