red phosphorus flame-retardant masterbatch can be used in engineering Plastics: PA6，PA66，PBT，PET，PC，MC nylon
High Properties
1.  Good effectiveness for flame retardants (FR) => UL94V-0, low product density
2.  Little inferior effect on physical properties of base polymer
3.  High Tracking-Index Value

Good Stability
1.  Inorganic FR, non volatile up to 300°C. Thermal stable at the processing temperature used for engineering plastics, i.e. ≥220°C for PA6, ≥260°C for PA66
2.   Non-migration, no blooming, low solubility in water
3.   Less smoke rate
4.   Non corrosive, stabilized RPM series provide moisture resistance, no phosphoric acid produced.
5.   Stable production line can provide continuous and uniform products.

Good Safety
1.   No HCl, HBr gas produced at fire. No Cd, Hg, Cr+6, less Pb
2.   Non toxicity, minimized phosphine
3.  Safety and no danger when use and transport, fire temperature more than 320°C
4.   Master batch shows more advantages in use, no dust pollution

Method of using:
Generally, drying is not required before processing, can be mixed with resin and different kinds of processing agents. If it is wet during transportation, the drying should be done for 4-6 hours before usage.

Packaging, Storage and transportation:
1. The masterbatche is packaged by two-layer bag, 25 KG per package.
