PX-200 (Resorcinol bis (2.6-dixylenyl phosphate) / RDX)
■ Structural Formula

C38H40O8P2
■ Features
Halogen & TPP Free
High HDT & High Hydrolysis Resistance than BDP
Izod Impact Strength can be kept higher than BDP
Suitable for hotmelt adhesives with a melting point of about 92°C
Low dielectric properties provide less damage for Relative Permittivity (εr) and Loss Tangent (tanδ) than conventional reactive flame retardants
Powder/Granular appearance
Soluble in solvents such as MEK
■ Applications
Used as a flame retardant for various engineering plastics and synthetic fibers such as PC/ABS compounds, etc. Its high HDT contributes to thinner and lighter plastic parts.
Effective with oxygen-containing resins such as modified-PPE, phenol, epoxy, and polyurethane
For electronic material applications, used in phenolic, epoxy or modified-PPE laminate applications such as PCB.
Used to add flame retardant and low-dielectric property functions to high-frequency components such as 5G and millimeter wave.
Provides flame retardancy and plasticity to hot melt adhesives.
