Description

Diphenyl Octyl Phosphate is an organophosphate ester widely recognized for its utility as a flame retardant and plasticizer. This compound matters for its ability to impart flame resistance and improve flexibility in polymer matrices without compromising performance. It is primarily needed by manufacturers in the plastics, rubber, and coatings industries seeking effective halogen-free flame retardant solutions.

Application

• As a flame retardant plasticizer for polyvinyl chloride (PVC) and other vinyl polymers.
• As an additive in engineering plastics and thermoplastics to enhance fire safety.
• In the formulation of fire-resistant hydraulic fluids and lubricants.
• As a component in flame-retardant coatings and adhesives.
• As a synergistic agent in combination with other flame retardants for improved efficacy.
• In the production of flexible foams and elastomers requiring flame resistance.
• For cable and wire insulation compounds to meet fire safety standards.
