33) Santoprene®
Santoprene® thermoplastic vulcanizates (TPVs) yog cov ua tau zoo elastomers uas ua ke cov yam ntxwv zoo tshaj plaws ntawm cov roj hmab vulcanized-xws li hloov pauv tau thiab teeb tsa qis-nrog kev ua kom yooj yim dua ntawm cov yas. Hauv cov neeg siv khoom thiab cov khoom lag luam thov, kev sib xyaw ntawm Santoprene TPV cov khoom thiab kev yooj yim ntawm kev ua haujlwm muab kev ua tau zoo dua qub, zoo ib yam thiab txo tus nqi tsim khoom. Hauv kev siv tsheb, lub cev hnyav ntawm Santoprene TPVs pab txhawb kev txhim kho kev ua haujlwm, roj kev lag luam thiab txo nqi. Santoprene tseem muaj ntau cov txiaj ntsig hauv cov khoom siv, hluav taws xob, kev tsim kho, kev noj qab haus huv thiab daim ntawv thov ntim khoom. Nws kuj tseem siv tau ntau dua cov khoom xws li txhuam txhuam, tuav, thiab lwm yam.
34) TPU (Isoplast®)
Ameslikas tsim los rau kev kho mob, TPU muaj nyob rau hauv cov iav ntev ntev uas muaj cov qib fiber ntau. TPU ua ke ua kom tawv thiab ruaj khov ntawm amorphous resins nrog tshuaj lom neeg ua haujlwm ntawm cov khoom siv lead ua. Cov qib fiber ntau ntev muaj zog txaus los hloov qee cov hlau hauv kev nqa cov ntawv thov. TPU tseem yog dej hiav txwv thiab tiv taus UV, ua rau nws zoo rau kev siv hauv qab dej.
Cov qib kawm: 40% ntim iav ntev, 30% luv iav puv, 60% iav ntev ntim
35) UHMW®
Ultra High Molecular Luj (UHMW) Polyethylene feem ntau raug xa mus ua lub ntiaj teb nyuaj tshaj plaws polymer. UHMW yog cov kab tawm, ultra-ntom polyethylene uas muaj qhov ua kom siab tiv taus nrog rau lub zog muaj zog. UHMW kuj tseem tiv taus tshuaj lom thiab muaj cov coefficient qis ntawm kev sib txhuam uas ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev thov. UHMW tuaj yeem hla kev sib txuas, rov kho dua, xim sib xws, ua haujlwm thiab tsim kom tau raws li cov neeg siv khoom feem ntau xav tau. Nws yog extrudable tab sis tsis tuaj yeem txhaj tshuaj. Nws lub ntuj zoo ua rau siv dav rau skids, zog, hav txwv yeem, thiab lwm yam kev siv uas zawv zawg, meshing lossis lwm yam kev sib cuag xav tau, tshwj xeeb hauv kev lag luam papermaking.
36) Vespel®
Vespel yog cov khoom ua tau zoo polyimide. Nws yog ib qho ntawm kev ua tau zoo tshaj plaws plastics engineering tam sim no muaj. Vespel yuav tsis yaj thiab tuaj yeem ua haujlwm tsis tu ncua los ntawm qhov kub kom txias txog 550 ° F (288 ° C) nrog kev mus rau 900 ° F (482 ° C). Cheebtsam Vespel tsis tu ncua nthuav tawm cov kev ua tau zoo tshaj plaws hauv ntau yam kev thov xav tau hnav tsawg thiab lub neej ntev nyob hauv ib puag ncig hnyav. Nws tuaj yeem siv rau cov nplhaib sib khi, cov tshuab ntxhua khaub ncaws thiab cov discs, cov ntoo, cov kabmob flanged, plungers, lub tshuab nqus tsev, thiab cov cua sov thiab hluav taws xob insulators. Nws ib qho tsis zoo yog nws tus nqi siab. A ¼ "txoj kab uas hla, 38" ntev, tuaj yeem raug nqi $ 400 lossis ntau dua.
