CAS 25104-37-4 PEVE yog dab tsi?
Poly (Ethyl Vinyl Ether) PEVEtshwm raws li cov kua ntshiab uas tsis muaj xim tsis muaj dej kub npau npau (35-36 degree) nrog cov ntxhiab tsw zoo li ether. Flash point hauv qab -50 degree F. Tej zaum yuav polymerize exothermically yog rhuab los yog paug. Yog tias polymerization tshwm sim hauv lub thawv, lub thawv tuaj yeem tawg ua rau hnyav. Tsawg dua dej thiab me ntsis soluble hauv dej. Yog li ntawd floats ntawm dej.
