Trade Mark:PSPPP

Polysulfonyldiphen ylenephenyl Phosphonate is a polymeric halogen-free flame retardant with a high decomposition temperature (350°C) and a controlled melting point of 130-180°C. It is particularly suitable for the flame retardant modification of polyester spinning and film materials, and can also be used as an auxiliary flame retardant in other plastics such as PMMA, PC, ABS and PP. With an addition of 4%-7%, it has high transparency, good physical and mechanical properties, good processing fluidity and a wide range of applications. In addition, due to the presence of sulphur in the structure, it can improve the corrosion resistance of the polymer.
