Irinda kwangirika no kudashira kw'ubushyuhe bwinshi, TPU ya polyether yo gufunga amavuta

Elastomer ya polyurethane ya Thermoplastic (TPU) ni ubwoko bwa elastomer ishobora guhindurwa pulasitiki ishyushye kandi igashonga hakoreshejwe solvent. Ifite imiterere myiza cyane nko gukomera cyane, gukomera cyane, kudashira no kudakoresha amavuta. Ifite imikorere myiza yo gutunganya kandi ikoreshwa cyane mu nganda zo kurinda igihugu, ubuvuzi, ibiribwa n'izindi. Polyurethane ya Thermoplastic hasUbwoko bubiri: ubwoko bwa polyester n'ubwoko bwa polyether, uduce tw'umweru twihariye cyangwa inkingi, kandi ubucucike ni 1.10 ~ 1.25g / cm3. Ubucucike bw'ubwoko bwa polyether ni buto ugereranije n'ubwo mu bwoko 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 bworoshye bw'ubwoko bwa polyether n'ubwoko bwa polyester buri hasi ya -62 ℃, kandi ubushyuhe buke bw'ubwoko bwa polyether buruta ubw'ubwoko bwa polyester. Ibintu bitangaje bya polyurethane thermoplastic elastomers ni ubudahangarwa bwiza bwo kwangirika, ubudahangarwa bwiza bwa ozone, ubukana bwinshi, imbaraga nyinshi, ubukana bwiza, ubushyuhe buke, ubudahangarwa bwiza bw'amavuta, ubudahangarwa bw'imiti n'ubudahangarwa bw'ibidukikije. Ubudahangarwa bw'amazi mu bwoko bwa ester buri hejuru cyane ugereranyije n'ubwo mu bwoko bwa polyester.
