PPSU-FR
Halogen-free flame retardant PPSU is a composite material modified by incorporating halogen-free flame retardant systems (such as phosphorus-based, nitrogen-based, or inorganic hydroxides) into the PPSU resin. PPSU inherently possesses flame retardancy (UL94 V-0), but certain special applications (such as rail transit, aviation) require higher flame retardant ratings or lower smoke density and toxicity indices. This product achieves a higher level of flame retardant safety while maintaining PPSU's excellent heat resistance and mechanical properties, and is halogen-free, complying with environmental regulations.
