The red phosphorus masterbatch produced by our company is a highly efficient and environmentally friendly halogen-free flame retardant, with advantages such as low addition amount and wide application. It is a dark red particle manufactured by combining microencapsulated red phosphorus with an inorganic flame retardant, using matrix resin as a carrier, which solves the safety issues of ordinary red phosphorus such as easy moisture absorption, poor compatibility with polymer materials, and particularly easy spontaneous combustion.

Our company's red phosphorus masterbatch has the following characteristics:
1. It produces low smoke and has good flame retardant efficiency;
2. No dust pollution, excellent processing performance;
3. Low density, good thermal stability, minimal reduction in physical properties of products;
4. No blooming, no migration, no corrosion to molds during processing.
5. Products have high comparative tracking index (CTI), offering significant advantages in electronic and electrical applications.
The main disadvantage of red phosphorus masterbatch is the color issue; apart from dark red and black, it cannot provide more color options for products. When used for flame retardancy of materials lacking oxygen elements such as general plastics, polyolefins, and rubber, it is best to use it in combination with magnesium hydroxide and aluminum hydroxide; when used for flame retardancy of materials rich in oxygen elements such as PET, PC, PBT, and PA, it can be used alone.
