Ibinyabutabire bya TPU/Thermoplastic Polyurethane Tpu Granules/ibinyabutabire by'insinga n'insinga

Elastomer ya polyurethane ya Thermoplastic (TPU) ni ubwoko bwa elastomer ishobora guhindurwamo pulasitiki binyuze mu gushyushya no gushonga hakoreshejwe solvent. Ifite imiterere myiza cyane nko gukomera cyane, gukomera cyane, kudashira no kudashira no kudakoresha amavuta. Ifite imikorere myiza yo gutunganya kandi ikoreshwa cyane mu nganda zo kurinda igihugu, ubuvuzi, ibiribwa n'izindi nganda. Polyurethane ya Thermoplastic ifite ubwoko bubiri: ubwoko bwa polyester n'ubwoko bwa polyether, uduce tw'umweru twihariye cyangwa uduce tw'inkingi, kandi ubucucike ni 1.10 ~ 1.25g / cm3. Ubucucike bw'ubwoko bwa polyether ni buto ugereranije n'ubw'ubwoko bwa polyester. Ubushyuhe bw'impinduka mu kirahuri bw'ubwoko bwa polyether ni 100.6 ~ 106.1 ℃, naho ubushyuhe bw'impinduka mu kirahuri bw'ubwoko bwa polyester ni 108.9 ~ 122.8 ℃. Ubushyuhe bw'ubukonje bw'ubwoko bwa polyether n'ubwoko bwa polyester buri hasi ya -62 ℃, kandi ubushyuhe buke bw'ubwoko bwa polyether ni bwiza ugereranyije n'ubw'ubwoko bwa polyester. Ibintu bidasanzwe bya elastomer za polyurethane thermoplastic ni ubudahangarwa bwiza bwo kwangirika, ubudahangarwa bwiza bwa ozone, ubukana bwinshi, imbaraga nyinshi, ubushyuhe bwiza, ubudahangarwa bwiza bwo hasi, ubudahangarwa bwiza bwa peteroli, ubudahangarwa bwiza bwa chimique no kudahangarwa n'ibidukikije. Ubudahangarwa bwa ester mu bwoko bwa hydrolytic buri hejuru cyane ugereranyije n'ubwo mu bwoko bwa polyester.
