Halogen-free phosphorus-based flame retardant offering excellent fire safety performance without releasing corrosive or toxic fumes during combustion.
High thermal stability enabling processing at typical engineering polymer temperatures (up to 300 °C) without significant decomposition.
Good compatibility and dispersion in polyamide (PA6, PA66), polybutylene terephthalate (PBT), and other engineering thermoplastics.
Low volatility and minimal plate-out tendency, supporting stable long-term processing and high surface quality of molded parts.
Complies with major environmental and regulatory requirements including RoHS, REACH, and UL94 V-0 (at appropriate loading levels).
Electrical and electronic components such as connectors, switches, circuit breakers, and housing parts.
Automotive interior parts including dashboard components, junction boxes, and sensor housings.
Industrial equipment housings requiring UL94-rated flame resistance and mechanical robustness.
Consumer appliance casings and structural parts where halogen-free fire protection is mandated.
3D printing filaments based on flame-retarded polyamides for functional prototyping and end-use parts.
