NTA & APPLICATIONS
TMAB yog ib qho symmetrical molecular structural aromatic diamine uas muaj ester pawg nrog ntau dua melting point.
TMAB feem ntau yog siv los ua tus neeg sawv cev kho rau polyurethane prepolymer thiab epoxy resin. Nws yog siv nyob rau hauv ntau yam elastomer, txheej, nplaum, thiab potting sealant daim ntaub ntawv.
Nws muaj dav ua latitude. Lub tshuab elastomer tuaj yeem ua los ntawm tes lossis tsis siv neeg style. Nws yog tsim nyog rau cov txheej txheem kub casting nrog TDI (80/20) hom urethane prepolymers. Cov polyurethane elastomer muaj cov khoom zoo heev, xws li cov khoom siv zoo, ua haujlwm kub, tiv thaiv hydrolysis, hluav taws xob, tshuaj tiv thaiv (xws li roj, hnyav, noo noo thiab ozone kuj).
Toxicity ntawm TMAB yog tsawg heev, nws yog Ames tsis zoo. TMAB yog FDA pom zoo, tuaj yeem siv rau hauv kev tsim cov polyurethane elastomers npaj hu rau zaub mov.
