Summary
A new non-halogen flame retardant has been developed and is useful for a variety of high performance applications. This non-reactive phosphorus-based material satisfies fire safety needs for a broad range of resins including epoxy, polyolefin, and polyamide.
The combination of excellent flame retardant efficiency, high thermal stability and exceptional electrical properties is unique to this organophosphorus flame retardant and makes it a breakthrough technology for high speed, high frequency use in fast growing wireless and wired infrastructures. Resin performance data, including formulations with synergists, are presented in this paper.
Conclusions
As technology progresses, so does the need for advanced materials. Anticipating this need, this material was developed as a high performance non-halogenated flame retardant technology. This new flame retardant can be processed at high temperatures and has a unique combination of high flame retardant efficiency, high thermal stability and superior electrical properties.
It can be applied in many different resin systems such as those used in printed circuit boards, aerospace, films and fibers, wire and cable, and connector applications. With a high melting point, it is melt blendable in applications where resins are processed at high temperature. The performance characteristics of this flame retardant make it attractive for a broad range of applications.
