Description

Diphenyl Xylyl Phosphate 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 safety and durability of polymer materials by imparting flame resistance without compromising on flexibility. It is primarily sought after by manufacturers in the plastics, rubber, and specialty coatings industries, where regulatory compliance and material performance are paramount.

Application

• As a primary flame retardant plasticizer in flexible polyvinyl chloride (PVC) applications such as cables, wires, and flooring.
• As a functional additive in engineering plastics and synthetic rubbers to improve fire safety ratings.
• In the formulation of fire-resistant hydraulic fluids and lubricants for industrial machinery.
• As a component in specialty coatings and adhesives requiring enhanced flame retardancy.
• For use in transportation interior materials, including automotive and aircraft components, to meet strict fire safety standards.
• In the production of electronic encapsulants and potting compounds to protect sensitive components.
