Description

Cresyl Diphenyl Phosphate (CDP) is a high-performance organophosphate ester widely recognized for its excellent flame-retardant and plasticizing properties. This compound is a critical additive for enhancing the fire safety and flexibility of various polymer systems without compromising their physical characteristics. It is an essential material for manufacturers in the plastics, electronics, and construction industries seeking reliable and efficient flame-retardant solutions.

Application

• As a primary flame retardant and plasticizer in flexible and rigid polyvinyl chloride (PVC) formulations for cables, wires, and flooring.
• As a key additive in engineering plastics such as polyphenylene oxide (PPO), polycarbonate (PC) blends, and other thermoplastics used in electronic housings and automotive components.
• In the production of fire-resistant synthetic rubbers and elastomers for industrial belts, seals, and gaskets.
• As a functional additive in adhesives, sealants, and coatings to improve flame retardancy and processing.
• Used in certain hydraulic fluid and lubricant formulations requiring fire-resistant properties.
• As a synergistic agent in combination with other flame retardants to enhance overall fire performance in polymer composites.
