Red Phosphorus Flame Retardant

Red phosphorus flame retardant is a kind of flame retardant represented by red phosphorus. It's purplish red or slightly brown. It's an inorganic non-halogen flame retardant with excellent thermal stability, nonvolatility, no corrosive gas, good flame retardancy, and good electrical insulation. In the process of use, there is no toxic hazard, the addition amount is small, it is insoluble, and the melting point is high.


Microencapsulated red phosphorus flame retardant is an outstanding flame retardant, featuring an excellent heat stability and a high fire retardant efficiency. By encapsulating red phosphorous in an organic resin, the compatibility between the red phosphorus and organic resin is improved, and the thermal stability, moisture absorption and resistance to migration of the flame retardant are greatly improved. It's with a higher fineness, uniform grain size and excellent dispersion. When being used in plastic materials, their physical performance won't be influenced. The microencapsulated red phosphorus flame retardant is provided with no dust particles, allowing for higher safety during transportation, storage and application.


Yinsu company has developed red phosphorus flame retardant for more than 20 years. In this process, we keep on improving technology, to increase the content of red phosphorus, reducing the addition amount in the production process, and providing customers with high-quality products.


Yinsu flame retardant is a factory, focuses on manufacturing non halogen, low smoke and non-toxic flame retardants for various of applications. It develops different chemical and plastic additive.
