CAS:63562-33-4

Molecular Formula:C17H15O6P

Molecular Weight:346.27

EINECS:426-480-5

Flame retardant DDP CAS 63562-33-4 has high melting point, good thermal stability and non-volatile type. The synthetic flame retardant slice can be drawn film, spun filament, strong dyeability, after multiple washing or dry cleaning, flame retardant performance does not migrate, does not decay. It has a long time flame retardant performance, and has the characteristics of low smoke density, good anti-droplet effect, and non-toxic smoke. Flame retardant DDP is a white powder with low solubility in hydrocarbon and ketone solvents and is easily soluble in DMF, DMSO and other organic solvents.
