Kev ntshiab siab 99% BTCA (1,2,3,4-Butanetetracarboxylic acid) CAS 1703-58-8
1,2,3,4-Butanetetracarboxylic acid (BTCA) yog ib qho tshuaj zoo meej uas tsis muaj formaldehyde thiab ruaj khov rau kev nias (DP). Nws muaj kev ua haujlwm siab thiab tsis muaj ntxhiab tsw phem. Ua los ntawm BTCA, cov ntaub xws li paj rwb thiab txhob lo lo ntxhuav tuaj yeem ua tiav cov yam ntxwv xws li tiv thaiv kev txiav, nias mus tas li thiab khaws cov duab thiab muaj lub zog siab.
1. BTCA siv tau los npaj cov ntaub ntawv polyimide. Hom khoom no muaj kev tiv thaiv cua sov zoo heev, tiv thaiv kua qaub, tiv thaiv hydrocarbon thiab cov khoom siv hluav taws xob zoo.
2. Siv tau los npaj ntau yam khoom siv polymer ua haujlwm, xws li cov ntaub ntawv photosensitive, cov ntaub ntawv kho mob polymer thiab cov ntaub ntawv polymer membrane ua haujlwm.
3. Siv tau los npaj cov nplhaib rwb thaiv hluav taws xob, cov hlau txheej thiab cov ntaub ntawv rwb thaiv hluav taws xob.
