Red Phosphorus Flame Retardant
FR is a series of halogen-free flame retardant master batch containing red phosphorus and polymer resin, for applications in
engineering thermoplastics, such as PA, PBT and PPO etc, as well as for improving the oxygen index of polyolefin.
FR is based on stabilized and micro-encapsulated fresh red phosphorus powder grade and polymer as a carrier resin. It is offered
as a non-dusting pellets form, easily to handle, accurate to dose and safe to process. It is easy to be homogenously
dispersed in the polymer compound.
Key Benefits
• High long-term stability, nearly no phosphorus acid and PH3, no corrosion to mold and Copper & Ag.
• RoHS compliant, REACH registration finished.
• Homogeneous dispersion, no dust, easily to handle.
• High thermal stability, excellent physical and electrical properties of FR compound.
