Polyester thiab TDI polyurethane prepolymeryog tsim los ntawm reacting polyester polyols nrog TDI, ua nyob rau hauv ib tug polymeric khoom nrog isocyanate pawg, muaj zoo abrasion kuj, zoo roj kuj, thiab zoo mechanical khoom.

Los ntawm kev ntxiv xim xim rau hauv PU prepolymer nws tuaj yeem muaj xim.

Tom qab lub tshuab nqus tsev degassing ntawm 80-85 degree, sib tov nrog melted MOCA, degassing, thiab ces casting, vulcanization molding.

Daim ntawv thov

Polyester thiab TDI polyurethane prepolymer yog cov khoom siv ntau yam siv hauv ntau lub lag luam.

Cov polyester thiab TDI polyurethane prepolymer muaj cov khoom siv zoo heev.
Piv txwv li, siab tensile lub zog, elongation, thiab tsim kua muag kuj.

Nws kuj pom zoo adhesion rau ntau yam substrates, ua rau nws haum rau daim ntaub ntawv nyob rau hauv coatings, adhesives, sealants, thiab elastomers.

Cov prepolymer no tuaj yeem ua tiav ntxiv los ntawm kev ntxiv cov tshuaj tua kab mob, catalysts, thiab lwm yam khoom ntxiv kom ua tiav cov khoom xav tau lossis kev ua haujlwm.

Nws tuaj yeem raug cam khwb cia, txau, lossis molded rau hauv ntau hom, ces dav siv hauv tsheb, rooj tog, khau, rwb thaiv tsev, thiab cov ntaub ntawv tsim kho.

FAQ

Vim li cas peb siv polyurethane?

Polyurethane yog cov khoom siv polymeric uas tuaj yeem ua ntau yam duab. Nws yog cov khoom ntawm kev xaiv rau ntau yam ntawm cov neeg siv kawg daim ntawv thov vim nws yuav raug hloov kho kom nruj los yog hloov tau.

Txhua hnub, peb siv polyurethanes hauv qee hom lossis lwm yam - hauv tsev, hauv peb lub chaw ua haujlwm thiab tsheb, rau kev ua si thiab kev lom zem, thiab thaum so.

Polyurethanes tsis yog tsuas yog pheej yig thiab nyab xeeb xwb, tab sis kuj yog cov khoom siv ntev ntev uas muab kev nplij siab thiab kev tiv thaiv rau peb lub neej txhua hnub.
