Insinga ya TPE VS Insinga ya TPU

TPE(Thermoplastic Elastomer) ni ibikoresho bya Thermoplastic Elastomer (Thermoplastic Elastomer) bifite imbaraga nyinshi, uburimbane bwinshi, inshinge zikozwe mu ifu, uburyo butandukanye bwo kubikoresha, kurinda ibidukikije, ntibihumanya kandi birinda uburozi, kandi bifite ibara ryiza cyane.

TPU(Thermoplastic Urethane), izwi mu Gishinwa nka Thermoplastic polyurethane elastomer, ni ubwoko bwa TPE. TPU ni ubwoko bw'ibikoresho bya polymer bigizwe na diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol na chain extender.

Ii. Itandukaniro riri hagati ya TPE na TPU:

1. Itandukaniro ryihariye ry'uburemere:

TPE (0.89 ~ 1.3);

TPU (1.0 ~ 1.4);

2. Itandukaniro mu kurwanya amavuta

Kurwanya amavuta ya TPE ni ikibazo gikomeye, ariko kumva neza, byoroshye kandi byoroshye;

TPU ifite ubushobozi bwo guhangana n'amavuta neza, amaboko yayo arakomera cyane kandi nta bushyuhe bwinshi ifite.

3. Itandukaniro mu guhangana n'ubushyuhe:

TPE (-60 ℃ ~ 105 ℃);

TPU (-60 ℃ ~ 80 ℃);

Umugozi wa WenChang TPU

Insinga ya WenChang TPE

4. Itandukaniro mu guhangana n'ubudahangarwa n'ubudahangarwa:

TPU ifite ubushobozi bwo kwihanganira no kwangirika kurusha TPE.

5. Itandukaniro mu bwoko bw'ubukomere:

TPE (0~100A);

TPU(35~90A, 50~80D), ubukana bukunze kugaragara ni 80~95A. TPU ifite ubukana bwa 50~80D ntabwo ikunze gukoreshwa mu bikorwa. Ubukana bwa 35~75A TPU, ikiguzi kinini cy'ibikoresho. TPU irangwa n'ubukana bwinshi n'ubudahangarwa bwiza bwo kwangirika. Ibiranga by'ingenzi ni: ubukana bwinshi, kandi uko ubukana bwiyongera, ibicuruzwa byayo biracyakomeza kuba byiza kandi bidashobora kwangirika, imbaraga nyinshi za mekanike, ubukonje bukabije, imikorere myiza yo gutunganya, ubukana bwa peteroli, ubukana bwa amazi, ubukana bwa mould, ubukana bwiza bwo kongera gukoreshwa.
