Chemical Name: aluminium hypophosphite
CAS: 7784-22-7
Aluminium hypophosphite is a halogen free flame retardant based on inorganic hypspophosphite. It is used as the base flame retardant for TPU, PU, TPE, PBT. It is always used with synergistic flame retardant component, such as MCA, APP, MPP, MC and other nitrogen series flame retardants.
