TPU Cov Ntaub Ntawv Xov Tooj

Thermoplastic polyurethane (TPU) yog ib qho ntawm ib chav kawm ntawm polyurethane plastics nrog ntau cov khoom, nrog rau elasticity , transparency , thiab ua hauj rau cov roj, roj thiab ua puas. Technically, lawv yog cov thermoplastic elastomers uas muaj cov kab ntim ntawm cov phab ntsa tawg uas muaj zog thiab muag muag.
Siv:
TPU muaj ntau daim ntaub ntawv nrog rau kev siv twj ntsuas hluav taws xob, cov log tsheb, cuab yeej hluav taws xob, khoom ua si, kev kho mob, tsav tsheb, neeg mob ntawm cov khoom siv hluav taws xob, xws li cov xov tooj ntawm tes. Nws tseem yog siv los ua cov keyboard protectors rau laptops.TPU yog paub zoo tias nws cov ntawv nyob hauv kev ua yeeb yam films, xaim thiab cable jacketing, hose thiab raj, hauv daim ntaub nplaum thiab textile txheej thiab ua ib qho hloov ntawm lwm cov polymers .. TPU pellets yog siv Adidas lub tshuab cushioning tsis ntev los no, hu ua Boost. Ob peb txhiab tus TPU pellets yog khi ua ke los tsim kom tau ib qho kev zoo rau lub khau.
Cov khoom ntawm TPU muag khoom muaj xws li:
kev puas tsuaj loj
tsawg-kub ua tau zoo
high shear zog
siab elasticity
transparency
roj thiab roj tuaj yeem ua haujlwm
TPUs tam sim no muaj peev xwm muab faib ua feem ntau nyob hauv ob pawg neeg, raws li cov xaim hluav taws xob:
polyester-based TPUs (tsuas yog muab los ntawm adipic acid esters )
polyether-based TPUs (mas yog raws li tetrahydrofuran (THF) ethers ).
Hauv ntawv, TPU raws li txoj cai tsuas yog siv rau cov rooj sib hais zoo heev uas yuav tsum tau ua kom zoo thiab kev tiv thaiv kab mob microbial, thiab thaum muaj huab tsis tshua muaj huab cua txias yooj yim.
Thaum lub teeb nruj xim thiab tsis-yellowing kev ua tau zoo, aliphatic TPU raws li aliphatic isocyanates siv.
Tsis ntev los no, BASF tau pioneered crosslinking thaum lub sij hawm TPU, ua tau los ntawm kev ntxiv cov crosslinkers kua thiab siv lub masterbatch . Kev cog raws li bio TPU tau tsim rau daim ntawv thov ntsuab thermoplastic elastomer los ntawm Merquinsa thiab GRECO, ua lag luam raws li Pearlthane ECO thiab Isothane feem. (Sau los ntawm Wikipedia)
Guanghai Hluav taws xob Cov khoom siv hluav taws xob, Ltd kev ua haujlwm nyob rau hauv hom rwb thaiv tsev, siv cov khoom noj nyom eco thiab tau dhau ROHS, SGS, FDA, REACH kuaj. Txhua yam uas xav tau ntawm cov khoom no, hu rau peb ncaj qha. Tsaug!
