Siv 7 txoj hauv kev los txheeb xyuas TPE thiab TPU!

TPE yog dav hais lus dav dav rau tag nrho cov thermoplastic elastomers.Nws raug cais raws li hauv qab no:

Tab sis feem ntau hu ua TPE yog kev sib xyaw ntawm SEBS / SBS + PP + naphthenic roj + calcium carbonate + auxiliaries.Nws tseem yog hu ua ib puag ncig tus phooj ywg mos yas hauv kev lag luam, tab sis qee zaus nws yog hu ua TPR (nws feem ntau hu ua hauv Zhejiang thiab Taiwan).TPU, tseem hu ua polyurethane, muaj ob hom: polyester hom thiab polyether hom.

TPE thiab TPU yog ob qho tib si cov ntaub ntawv thermoplastic nrog roj hmab elasticity.TPE thiab TPU cov ntaub ntawv uas zoo sib xws tuaj yeem qee zaum nyuaj rau kev paub qhov txawv ntawm TPE thiab TPU los ntawm kev saib lawv ntawm qhov muag liab qab.Tab sis pib nrog cov ntsiab lus, peb tseem tuaj yeem txheeb xyuas qhov sib txawv thiab qhov sib txawv ntawm TPE thiab TPU los ntawm ntau yam.

1.Kev pom tseeb

Lub pob tshab ntawm TPU yog zoo dua li ntawm TPE, thiab nws tsis yooj yim los lo zoo li pob tshab TPE.

2. Loj

Qhov kev faib ua feem ntawm TPE sib txawv, xws li ntawm 0.89 txog 1.3, thaum TPU nyob ntawm 1.0 txog 1.4.Qhov tseeb, thaum lawv siv, lawv tsuas yog tshwm sim nyob rau hauv daim ntawv ntawm kev sib tov, yog li qhov tshwj xeeb lub ntiajteb txawj nqus hloov pauv zoo heev!

3. Roj kuj

TPU muaj roj zoo, tab sis nws nyuaj rau TPE kom tsis txhob muaj roj.

4.Tom qab hlawv

TPE muaj lub teeb tsw ntxhiab tsw thaum hlawv, thiab cov pa taws kub hnyiab yog me me thiab lub teeb.TPU combustion muaj qee yam tsw ntxhiab tsw, thiab muaj suab nrov me ntsis thaum hlawv.

5.Mechanical zog

TPU lub elasticity thiab elastic rov qab zog (flexion resistance thiab creep resistance) zoo dua li TPE.

Qhov laj thawj tseem ceeb yog tias cov khoom siv ntawm TPU yog cov qauv polymer homogeneous thiab belongs rau pawg polymer resin.TPE yog cov khoom siv alloy nrog ntau theem qauv aggregated los ntawm ntau cov khoom sib xyaw.

High-hardness TPE ua yog nquag rau cov khoom deformation, thaum TPU qhia tau zoo heev elasticity nyob rau hauv tag nrho cov hardness ranges, thiab cov khoom tsis yooj yim rau deform.

6.Qhov kub tsis kam

TPE yog -60 ° C ~ 105 ° C, TPU yog -60 ° C ~ 80 ° C.

7.Qhov tshwm sim thiab hnov

Rau qee cov khoom siv overmolded, cov khoom ua los ntawm TPU muaj kev xav ntxhib thiab muaj zog kev sib txhuam;Thaum cov khoom ua los ntawm TPE muaj qhov muag muag thiab muag muag thiab kev sib txhuam tsis muaj zog.

Txhawm rau ua kom tiav, TPE thiab TPU yog cov khoom muag muag thiab muaj cov roj hmab zoo elasticity.Nyob rau hauv kev sib piv, TPE yog zoo heev nyob rau hauv cov nqe lus ntawm tactile kev nplij siab, thaum TPU qhia tau zoo heev elasticity thiab lub zog.
