Description

Bis(Isopropylphenyl) Phenyl Phosphate is an organophosphate compound widely used as a high-performance flame retardant and plasticizer. Its primary commercial value lies in its excellent thermal stability and compatibility with various polymer matrices, enhancing material safety and durability. This product is essential for manufacturers in the plastics, electronics, and construction industries seeking to meet stringent fire safety regulations without compromising material properties.

Application

• Primary flame retardant and plasticizer for engineering thermoplastics like polycarbonate (PC), polyphenylene oxide (PPO), and their blends.
• Key additive in wire and cable insulation formulations to improve fire resistance and flexibility.
• Functional plasticizer for PVC and synthetic rubber applications requiring low volatility and good electrical properties.
• Component in electronic encapsulants and circuit board laminates to enhance flame retardancy.
• Used in adhesives, sealants, and coatings where fire safety is a critical requirement.
• Potential additive in hydraulic fluids and lubricants for its anti-wear and flame-retardant characteristics.
