Polyether thiab TDI polyurethane prepolymeryog ib qho thermosetting polyurethane prepolymer ua los ntawm polyether polyol thiab TDI (toluene diisocyanate) thiab lwm yam khoom siv raw, tuaj yeem siv rau hauv ntau daim ntawv thov.
Daim ntawv thov
Cov khoom siv elastomeric: Polyether TDI Polyurethane Prepolymer tuaj yeem siv los ua cov khoom elastomeric.
Xws li cov ntsaws ruaj ruaj, springs, thiab roj hmab qhov chaw.
Nws muaj qhov zoo elastic rov qab, hnav tsis kam thiab lwm yam.
Cov ntaub ntawv rwb thaiv tsev: Polyether hom TDI prepolymer ua npuas ncauj khoom zoo rau rwb thaiv tsev thiab thermal rwb thaiv tsev. Vim tias muaj zog rwb thaiv tsev thiab thermal conductivity tsawg.
Polyether raws li polyurethane prepolymers muaj cov nplaum zoo heev thiab ua kom zoo, tuaj yeem siv los ua cov khoom muab tub lim xws li muab tub lim thiab cov nplaum.
Qhov zoo
Polyether TDI polyurethane prepolymer muab cov khoom siv zoo xws li lub zog siab, hnav tsis kam, thiab kav ntev.
Nrog lub neej ua haujlwm ntev, nws tuaj yeem tiv taus cov kab mob siab thiab thauj khoom.
Thermal stability: TDI polyether prepolymers muaj qhov tshwj xeeb thermal stability ntawm qhov kub thiab txias thaum tuav txhua yam thiab tshuaj stability.
Los ntawm kev hloov cov qauv thiab cov khoom siv, cov yam ntxwv ntawm polyether polyurethane prepolymer tuaj yeem ua kom haum rau tus neeg xav tau kev pab. Qhov no ua rau lawv haum rau qee yam kev siv xws li hardness, yooj, thiab dej nqus.
Cov polyether raws li polyurethane prepolymers kuj yog resistant rau ntau yam tshuaj thiab cov kuab tshuaj, nrog rau corrosion.
Xim tuaj yeem hloov tau los ntawm kev ntxiv xim.
Kho los ntawm MOCA lossis lwm tus neeg sawv cev auring.
Nws tuaj yeem ntim rau hauv 20kg lossis 200kg ib nruas.
