RDP is a non-halogen Flame Retardant (FRs) with low viscosity, good thermal stability and low volatility.
As a low polymerization phosphate flame retardant, RDP has good low volatility, low viscosity and thermal stability during production and application, and meets the processing requirements of most plastic products, engineering plastics and synthetic fiber.

Uses:
RDP is suitable for various plastics processing, such as PPO (PPE), polyphenylene ether alloy, PC/ABS, terephthalate based polymers (PET, PBT).
