TPE (Thermoplastic Elastomer) thiabTPU (Thermoplastic Polyurethane)yog ob qho tib si thermoplastic elastomers, tab sis lawv muaj qhov sib txawv ntawm lawv cov muaj pes tsawg leeg, cov khoom, thiab kev siv. Cia peb delve rau hauv qhov sib txawv ntawm TPU vs TPE kom nkag siab txog lawv cov yam ntxwv tshwj xeeb ntau dua.
Kev sib xyaw:
TPEs feem ntau yog tsim los ntawm cov thermoplastic matrix nrog cov roj hmab dispersed. Qhov kev sib xyaw ua ke no muab TPEs nrog kev hloov pauv, kev ua haujlwm, thiab elasticity feem ntau cuam tshuam nrog cov khoom siv roj hmab. Cov roj hmab tivthaiv tso cai rau TPEs tau yooj yim ncab thiab deformed yam tsis muaj deformation mus tas li.
TPUs yog muab los ntawm cov tshuaj tiv thaiv ntawm diisocyanates thiab polyols, uas ua rau ib tug polymer nrog alternating nyuaj thiab mos ntu. Qhov kev sib xyaw ua ke no muab TPUs lawv qhov toughness, durability, thiab yooj. Cov ntu hloov pauv ua rau muaj txiaj ntsig zoo ntawm cov khoom siv TPUs, xws li lub zog tensile siab thiab kev puas tsuaj.
Hardness Range:
TPEs muaj ntau hom hardness ntau dua piv rau TPUs. Lawv tuaj yeem sib txawv ntawm cov mos mos (xws li, gel-zoo li) mus rau ib nrab nruj, muab ntau yam hauv kev ua tau raws li cov ntawv thov sib txawv. Lub hardness ntawm TPEs tuaj yeem hloov kho qhov sib piv ntawm cov thermoplastic matrix thiab roj hmab hais.
TPUs kuj muaj ntau theem hardness, tab sis lawv zoo li nruj dua piv rau TPEs. TPUs tuaj yeem ua tau los ntawm cov mos mos thiab hloov tau mus rau nruj thiab tawv, ua rau lawv haum rau cov ntawv thov uas xav tau ob qho tib si durability thiab yooj. Lub hardness ntawm TPUs tuaj yeem hloov kho los ntawm kev kho qhov sib xyaw thiab cov qauv ntawm cov ntu tawv thiab mos.
Mechanical Properties:
TPEs nthuav dav elasticity thiab yooj yooj yim, cia lawv rov ua dua thiab rov zoo dua yam tsis muaj deformation mus tas li. Lawv muaj kev tiv thaiv zoo, kev cuam tshuam, thiab lub zog tsim kua muag. TPEs paub txog lawv qhov muag muag thiab tactile, muab kev tuav zoo. Txawm li cas los xij, lawv tuaj yeem muaj lub zog tensile qis dua thiab kev puas tsuaj piv rau TPUs.
TPUs muaj lub zog tensile siab, tsis kam tiv taus, thiab elongation zog. Lawv tuaj yeem tiv taus daim ntawv thov hnyav thiab muab kev ua haujlwm zoo dua. TPUs nthuav tawm ob qho tib si yooj yooj yim thiab toughness, muab qhov sib npaug ntawm elasticity thiab rigidity. Lawv paub txog lawv cov resilience thiab muaj peev xwm tiv taus tej yam kev xav tau.
Chemical Resistance:
TPEs feem ntau muaj kev tiv thaiv zoo rau cov tshuaj, roj, thiab cov kuab tshuaj, tab sis lawv cov kev tiv thaiv kuj yuav txawv nyob ntawm cov qauv tsim. Nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev thov tshwj xeeb thiab xaiv TPE qib nrog cov tshuaj tiv thaiv tsim nyog.
TPUs ua kom pom cov tshuaj tiv thaiv zoo heev, ua rau lawv haum rau cov ntawv thov uas yuav tsum tau raug rau cov khoom hnyav thiab ib puag ncig. Lawv tuaj yeem tiv taus kev sib cuag nrog roj, roj, tshuaj, thiab ntau cov kuab tshuaj yam tsis muaj kev puas tsuaj loj, ua rau lawv zoo tagnrho rau kev thov kev lag luam.
Cov txheej txheem ua:
TPEs tuaj yeem ua tau yooj yim siv cov txheej txheem xws li txhaj tshuaj molding, extrusion, thiab tshuab moulding. Lawv muaj cov dej ntws zoo zoo, tso cai rau cov qauv tsim thiab cov duab zoo sib xws kom ua tiav. TPEs tuaj yeem raug overmolded mus rau lwm cov ntaub ntawv, nthuav lawv txoj kev tsim.
TPUs kuj muaj peev xwm ua tau rau ntau txoj hauv kev, suav nrog kev txhaj tshuaj molding thiab extrusion. Lawv nthuav tawm cov yam ntxwv zoo yaj ntws, ua kom yooj yim tsim cov khoom sib txawv thiab cov khoom sib xyaw. TPUs tuaj yeem ua tiav siv cov txheej txheem txhaj tshuaj molding los ua ke cov khoom sib txawv lossis xim hauv ib kauj ruam tsim khoom.
Daim ntawv thov:
TPEs pom cov ntawv thov hauv ntau qhov kev lag luam, suav nrog tsheb, khoom siv, khoom siv hluav taws xob, khoom siv kho mob, thiab lwm yam. Lawv feem ntau yog siv rau cov mos-kov tuav, ntsaws ruaj ruaj, gaskets, hloov tau yooj yim, thiab kev co-damping daim ntaub ntawv. TPEs kuj tau txais koob meej hauv kev lag luam khau rau khau insoles, cov ntaub ntawv cushioning, thiab cov khau yooj yim.
TPUs tau siv dav hauv cov khoom siv tsheb, khau, khau kis las, cov khoom lag luam, khoom siv hluav taws xob, thiab lwm yam. Lawv cov tawv tawv, tawv tawv, thiab kev ua kom yooj yim ua rau lawv tsim nyog rau kev siv xws li tsheb ntsaws ruaj ruaj, hoses, siv tawv, tiv thaiv npog, rwb thaiv tsev cable, khoom ntaus pob ncaws pob, thiab cov iav sab nraum zoov.
Hauv kev xaus, thaum ob qho tib si TPE vs TPU yog cov thermoplastic elastomers, lawv muaj qhov sib txawv ntawm cov khoom muaj pes tsawg leeg, hardness range, mechanical zog, chemical resistance, processing method, and applications.
