Description

Isopropyl Diphenyl Phosphate is an organophosphate compound widely recognized as an effective flame retardant and plasticizer. This specialty chemical is valued for its ability to impart flame resistance while maintaining favorable processing characteristics in polymer systems. It is primarily utilized by manufacturers in the plastics, rubber, and electronics industries seeking to enhance the safety and performance of their materials.

Application

• Primary flame retardant and plasticizer for engineering thermoplastics like polycarbonate (PC), polyphenylene oxide (PPO), and their blends.
• Key additive in flexible PVC formulations for wire and cable insulation, providing both flame resistance and flexibility.
• Functional plasticizer in synthetic rubber and elastomer compounds for automotive and industrial applications.
• Flame retardant component for electronic encapsulants, adhesives, and coatings where halogen-free solutions are required.
• Additive in hydraulic fluids and lubricants to improve fire resistance and thermal stability.
• Used in the formulation of certain specialty polymers and resins to meet specific fire safety standards (e.g., UL 94).
