"NDI elastomers yog lub npe hu ua 'tus huab tais ntawm hnav tsis kam' hauv kev lag luam polyurethane. Lawv tuaj yeem ua haujlwm ruaj khov ntawm -10℃~ 120℃thiab muaj lub neej ntev ntawm ntau tshaj 2,000 teev. Nws muaj cov khoom zoo xws li lub zog siab, kub tsis kam, thiab hydrolysis tsis kam.
NDI thiab Polyester Prepolymer muaj cov hauv qab no kom zoo dua:
Cov khoom siv hluav taws xob zoo heev: kev ua haujlwm zoo heev nyob rau hauv siab zaus thiab siab dynamic loads, siab resilience thiab qis endogenous tshav kub, haum rau hnyav -lub luag hauj lwm thiab siab - daim ntawv thov ceev
Qhov zoo ntawm hnav tsis kam thiab lub zog tsim kua muag: nws cov polyurethane elastomer muaj qhov hnav tsawg heev thiab lub zog tsim kua muag, thiab haum rau yooj yim - rau - coj qhov chaw xws li roj hmab rollers, lub log, thiab cov ntxaij vab tshaus.
Cov neeg kho tshuab nqa lub peev xwm siab: lub zog tensile tuaj yeem ncav cuag 64 MPa, uas tam sim no lees paub tias yog ib qho ntawm -kev ua tau zoo elastomers, uas zoo dua li cov qauv MDI lossis TDI.
Cov cua kub zoo: tuaj yeem ua haujlwm nyob rau hauv ib puag ncig ntawm 120℃rau lub sijhawm ntev, haum rau qhov kub thiab txias
Cov roj zoo heev thiab txiav tsis kam: kev ua haujlwm ruaj khov hauv roj av, metallurgy, luam ntawv thiab lwm yam lag luam
