Ua npuas yas yog ib qho ntawm ntau yam tseem ceeb ntawm polyurethane cov khoom siv hluavtaws, nrog cov yam ntxwv ntawm porosity, yog li nws qhov txheeb ze sib xws me me, thiab nws lub zog tshwj xeeb yog siab. Raws li qhov sib txawv ntawm cov ntaub ntawv raw thiab mis, nws tuaj yeem ua rau muag muag, ib nrab tawv thiab tawv polyurethane ua npuas yas thiab lwm yam.
PU ua npuas ncauj tau siv dav, yuav luag ntxig rau hauv txhua qhov haujlwm ntawm kev lag luam hauv tebchaws, tshwj xeeb tshaj yog hauv rooj tog, txaj, tsheb thauj mus los, tub yees, kev tsim kho, rwb thaiv tsev thiab ntau yam kev siv.
Polyurethane ua npuas ncauj feem ntau yog siv rau rooj tog, txaj thiab khoom siv hauv tsev, xws li rooj zaum thiab rooj zaum, nraub qaum, txaj thiab tog hauv ncoo.
Hauv kev tsim khoom thiab siv tiag, cov khoom no feem ntau yuav tsum tau ua raws qhov xav tau ntawm kev tiv thaiv daj thiab nplaim taws rov qab. Lub tuam txhab muab ntau yam tshuaj ntxiv tuaj yeem pab txhim kho kev ua tau zoo ntawm cov khoom.
Lub tuam txhab tuaj yeem muab hauv qab PU ua npuas ntxiv:

| UV ABSORBER | YIHOO UV 1 | Siv dav hauv PU, nplaum, ua npuas dej thiab lwm yam khoom siv. | ||
| YIHOO UV571 | TIAB SA 571 | Siv dav hauv cov thermoplastic PUR txheej thiab cov yas ua ib txheej, tawv yas polychloride, PVB, PMMA, PVDC, EVOH, EVA, kub ua kom tsis muaj polyester thiab PA, PET, PUR thiab PP fiber ntau tig AIDS. | ||
| YIHOO UV B75 | TINUVIN B75 | Compound UV nqus dej, feem ntau yog siv rau PU, nplaum lossis PUR txheej, xws li cov ntaub thaiv npog, ntaub ntaub thiab tawv tawv. | ||
| ANTIOXIDANT | TIAB SA 333 | JP333E | Phenol-free antioxidant, siv los pab tiv thaiv tshav kub hauv PVC, txhim kho cov xim thiab pob tshab ntawm cov khoom PVC. Nws kuj tseem tuaj yeem siv cov khoom siv roj hmab thiab PU txhawm rau txhim kho kev laus ua haujlwm ntawm cov khoom. | |
| YIHOO AN340 | Phenol free antioxidant, tuaj yeem siv dav hauv PVC, ABS, SBR, CR thiab lwm yam. | |||
| ZOO TSHAJ PLAWS | YIHOO FR950 | / | Chlorinated phosphate ester nplaim hluav taws, tshwj xeeb tshaj yog tsim rau nplaim taws retardant PU ua npuas ncauj. Nws tuaj yeem pab hla California 117 tus qauv, FMVSS302 tus qauv ntawm lub tsheb daim txhuam cev, Askiv tus qauv 5852 Crib 5 thiab lwm yam qauv ntsuas nplaim hluav taws. FR950 yog lub nplaim hluav taws zoo tshaj los hloov TDCPP (carcinogenicity) thiab V-6 (muaj carcinogen TCEP). |
Txhawm rau muab cov tshuaj polymer ntxiv rau hauv cov ntawv thov tshwj xeeb, lub tuam txhab tau tsim cov khoom lag luam npog hauv qab daim ntawv thov: PA polymerization & hloov kho ntxiv, PU ua npuas dej ntxiv, PVC polymerization & kev hloov kho ntxiv, PC ntxiv, TPU elastomer additives, qis VOC tsheb laij cov tshuaj ntxiv additives tus neeg sawv cev, txheej txheej ntxiv, tshuaj pleev ib ce ntxiv, API thiab lwm yam khoom siv tshuaj xws li zeolite thiab lwm yam.
