Isophthalic acid CAS 121-91-5
Isophthalic acid yog ib qho siv lead ua los ntawm dej los yog ethanol uas tsis muaj xim. Nws yaj me ntsis hauv dej, tsis yaj hauv benzene, toluene thiab roj av ether, yaj hauv methanol, ethanol, acetone thiab glacial acetic acid. Isophthalic acid muaj qee qhov kev pheej hmoo, yog tias hmoov los yog cov khoom me me sib xyaw nrog huab cua, tej zaum yuav muaj hmoov av tawg.

Isophthalic acid feem ntau yog siv rau hauv kev tsim cov unsaturated polyester resin, PET copolymer ntoo ntiv tes thiab alkyd resin. Tsis tas li ntawd, isophthalic acid ua cov khoom siv raw kuj tseem siv tau los npaj polyisophthalic acid allyl ester (DAIP) resin, uas yog siv dav hauv kev tsim cov khoom siv insulating kub thiab cov khoom siv impregnated. Kev npaj diethyl isophthalate (DEIP) ua cov tshuaj tshwj xeeb Chemicalbook hauv kev tsim cov toluene diisocyanate; Kev npaj polybenzimidazole siv ua cov nplaum rau aluminium alloy, stainless hlau thiab lwm yam khoom siv hlau, cov qauv honeycomb hlau, polyimide zaj duab xis, silicon wafer thiab lwm yam khoom siv; Diisooctyl isophthalate, cov roj tsis muaj xim kua yas nrog kev sib raug zoo nrog PVC, nitrocellulose, polystyrene thiab lwm yam resins, tau npaj.
25kg / nruas lossis raws li cov neeg siv khoom xav tau.
