Ntxiv nrog rau styrenic thiab olefinic thermoplastic elastomers, PVC-raws li TPE (TPVC/TCPE) thiab polyurethane-raws li TPE (TPU) ua lub luag haujlwm tseem ceeb hauv kev siv elastomer niaj hnub vim lawv cov yam ntxwv ua tau zoo.
PVC-Based Thermoplastic Elastomers (TPVC thiab TCPE)
PVC-raws li thermoplastic elastomers suav nrog TPVC (thermoplastic PVC elastomers) thiab TCPE (chlorinated polyethylene-raws li TPE). TPVC feem ntau yog ua tiav los ntawm kev hloov kho elastic ntawm PVC, feem ntau los ntawm kev sib xyaw ua ke ntawm NBR nrog PVC.
TPVC cov ntaub ntawv nthuav tawm cov txheej txheem compression zoo dua thiab roj hmab-zoo li kev yoog raws thaum khaws PVC qhov ua tau zoo. Lawv yog dav siv nyob rau hauv automotive tha xim sab hauv, kauj log, wiper hniav, hoses, cables, waterproof membranes, thiab muaj nplooj ntawv. Ntau tshaj 70% ntawm TPVC noj yog concentrated nyob rau hauv kev lag luam automotive.
PVC / NBR sib xyaw yog suav tias yog ib qho ntawm cov roj hmab-yas alloy zoo tshaj plaws thoob ntiaj teb. Txawm li cas los xij, vim muaj kev tswj hwm ib puag ncig thiab kev txhawj xeeb ntsig txog cov pa roj carbon monoxide, TPVC kev loj hlob tau qeeb hauv qee thaj tsam. Hauv Suav teb, TPVC cov ntaub ntawv tau siv ntau dua los hloov NR, CR, thiab NBR roj hmab hauv hoses, tso tsheb hlau luam, khau, thiab cov khoom lag luam.
Polyurethane-Based Thermoplastic Elastomers (TPU)
Thermoplastic polyurethane (TPU) yog tsim los ntawm thaiv copolymerization ntawm urethane nyuaj ntu thiab polyester lossis polyether mos ntu. TPU paub txog nws qhov tshwj xeeb ua kom puas, muaj zog txhua yam, roj ua haujlwm, thiab kev ua haujlwm qaug zog.
TPU yog dav siv nyob rau hauv cov khau kis las, khau boots, hoses, siv, films, cables, industrial parts, automotive Cheebtsam, thiab cov khoom kho mob. Kev txhaj tshuaj molding thiab extrusion yog thawj txoj hauv kev, suav txog ntau dua 75% ntawm TPU noj.
Kev tsim kho tshiab tsis ntev los no tau ua rau siab -TPU ntws, pob tshab TPU, iav-fiber reinforced TPU, IPN- qauv TPU, conductive TPU, thiab breathable TPU, nthuav dav nws daim ntawv thov ntau yam. TPU / PC sib xyaw ntxiv txhim kho kev cuam tshuam thiab kev nyab xeeb kev ua haujlwm hauv kev siv tsheb.
