CAS NO: 552-30-7 TMA / Trimellitic Anhydride

It is the inherent structural advantages that determine the comprehensive benefits: dual active sites achieve high crosslinking density and complete reaction, the mild and controllable reaction characteristics expand the process window and enhance the molding performance, the rigid aromatic ring framework endows the product with performance, and the excellent compatibility ensures the uniformity of the curing system.

Los ntawm cov qauv molecular ntawm tris-aromatic carboxylic anhydride, lub synthesized TOTM lov los ntawm kev ua tau zoo thiab ib puag ncig tiv thaiv bottlenecks ntawm phthalic acid-raws li plasticizers ntawm qib molecular: lub rigid benzene nplhaib molecular + tris - ester qauv endows { 4}} volatility thiab ultrahigh resistance cov khoom tseem ceeb. Qhov hnyav molecular + spatial steric hindrance ua tau zoo heev tiv thaiv kev tsiv teb tsaws thiab kev rho tawm, thiab cov tsis yog -phthalic qauv hauv paus daws teeb meem ib puag ncig thiab kev noj qab haus huv, thaum tseem coj mus rau hauv tus account lub plasticization efficiency thiab mechanical compatibility yuav tsum tau rau PVC ua.

Nws muaj F / H qib cua sov ua haujlwm, cov khoom siv hluav taws xob siab, thiab kev laus zoo heev ntawm cov tshuaj tsw qab acid anhydrides. Ntxiv mus, los ntawm kev ua haujlwm pab pawg sib piv ntawm ib qho kua qaub anhydride thiab ib pawg carboxyl, nws ua tiav cov kev tswjhwm hla - txuas network, lub qhov rais txheej txheem dav, thiab yooj yim. Nyob rau tib lub sijhawm, nws kuj muaj qhov zoo ntawm cov khoom siv raw khoom, cov nqi tswj tau, thiab ua raws li cov cai ntawm ib puag ncig, hais txog qhov tsis zoo ntawm lwm cov multi-acid anhydrides, uas muaj "siab kub tsis kam ua rau kev ua haujlwm tsis zoo, kev ua haujlwm zoo ua rau tsis muaj cua sov, thiab kev ua haujlwm zoo ua rau cov nqi siab".

1. Plasticizers
2. Resins thiab curing agents
3. Txheej thiab nplaum
TMA (CAS: 552-30-7) Dab tsi yog qhov cuam tshuam ntawm qhov kev faib ua feem ntawm cov khoom no ntxiv rau hauv cov hmoov av kub-resistant hmoov txheej ntawm qhov kub thiab txias thiab adhesion ntawm txheej?
TMA, raws li tus neeg sawv cev kho lossis tus neeg sawv cev crosslinking rau epoxy resins thiab polyester resins, ua tiav qhov ntom ntom ntom ntom - ester bond crosslinking network los ntawm ob qhov chaw nquag. Qhov sib ntxiv ntawm TMA ncaj qha txiav txim siab crosslinking ntom ntawm txheej, rigidity ntawm molecular saw, thiab adhesion rau substrate. Nws qhia tau hais tias muaj kev cuam tshuam tsis tu ncua ntawm qhov kub thiab txias thiab adhesion, thiab muaj qhov pom zoo sib xws.
