Pyromellitic Dianhydride CAS89-32-7/PMDA

Kev Siv

Pyromellitic Dianhydride siv tau los tsim cov polyimide resin, uas yog siv ua cov khoom siv raw rau cov xim rwb thaiv tsev uas tiv taus kub siab. Nws kuj tseem siv tau los tsim cov tshuaj epoxy resin curing agents thiab plasticizers, urea formaldehyde resin stabilizers, phthalocyanine xiav dyes, corrosion inhibitors, instant binders, electronic photography toners, thiab lwm yam.

Pyromellitic Dianhydride thiab nws cov derivatives muaj ntau yam kev siv. PMDA feem ntau yog siv los ua tus neeg sawv cev rau epoxy resin, ib qho khoom siv raw rau polyimide, thiab ib qho crosslinking tus neeg sawv cev rau polyester resin los tsim homopolymer polyetherimine resin. Qhov no yog cov khoom siv engineering kub siab uas tuaj yeem siv tas mus li ntev ntawm 2600C.

Cov khoom siv tseem ceeb siv rau kev tsim cov yas polyimide uas tiv taus cua sov thiab cov yeeb yaj kiab rwb thaiv tsev; Siv tau ua cov khoom siv hluavtaws rau epoxy resin curing agent, stabilizer, thiab zas xim, thiab lwm yam.

Pyromellitic Dianhydride siv tau los tsim cov polyimide resin, cov xim rwb thaiv tsev kub uas tiv taus kub, PVC plasticizer, cov neeg sawv cev sib txuas ua ke ntawm cov khoom siv hluavtaws, thiab cov neeg sawv cev kho epoxy resin. Nws kuj tseem siv tau los tsim cov xim phthalocyanine xiav, thiab lwm yam.
