Description
Microencapsulated Red Phosphorus (MRP) is a high-performance halogen-free flame retardant developed by advanced microencapsulation technology. By coating red phosphorus with a protective polymer or inorganic shell, it eliminates the inherent safety risks of raw red phosphorus, while maintaining excellent flame retardancy. This makes it ideal for demanding industrial applications where safety, stability, and consistent performance are critical

Key Advantages
- Enhanced Safety & Stability：The microencapsulation shell isolates red phosphorus from moisture, oxygen, and mechanical impact, eliminating risks of spontaneous combustion, hydrolysis, and phosphine release during storage, handling, and processing.
- High-Efficiency Flame Retardancy：Acts as an excellent char-forming agent, promoting the formation of a dense carbonaceous barrier that suppresses flame spread, reduces smoke emission, and prevents dripping.
- Low Loading & Broad Compatibility：Delivers outstanding flame retardant performance at low addition levels, preserving the mechanical strength, processability, and electrical properties of base polymers.
- Thermal Stability：With an ignition point ≥300°C, it withstands high-temperature processing conditions, making it suitable for engineering plastics requiring injection molding.
- Environmentally Friendly：Halogen-free, RoHS and REACH compliant, and free of toxic byproducts during combustion.
