9,10-Dihydro-9-oxo-10-phosphonophenanthrene-10-oxide（ DOPO )
Product Introduction
[Molecular formula]: C12H9PO2
[Molecular weight]: 216.17
[CAS number]: [35948-25-5]
[Description]: White crystalline powder or thin film, easily soluble in methanol, ethanol, chloroform, etc., soluble in benzene, toluene, chlorobenzene, etc., insoluble in water.
Quality Index：
Technical Parameter Premium grade
Content (%) ≥99.50
OPP content (ppm) ≤1000
Acid value (g) ≤300
Chromaticity (APHA) ≤100
Water absorption (%) ≤0.3
Melting point (℃) 117-120
[Application]: It can be used for linear polyester, polyamide, epoxy resin, polyurethane, and is widely used in plastics for electronic equipment, copper laminated circuit boards, and other aspects.
[Features]: DOPO has high thermal stability, oxidation resistance, and excellent water resistance. It is a reactive and additive flame retardant. Due to the presence of phosphorus carbon bonds, its flame retardant performance is better than that of general phosphate esters.
[Packaging]: 25kg paper bag.
[Storage and Transportation]: Handle with care, seal and store, do not get damp.
