Widely used as a flame retardant in engineering plastics such as polyamides (nylon) and polyesters, Aluminum Diethylphosphinate offers high thermal stability and excellent performance in both glass-filled and unfilled systems. It is particularly effective in electrical and electronic components, where it helps meet stringent flammability standards like UL94 V-0 without compromising mechanical properties. Its low smoke emission and halogen-free nature make it suitable for applications requiring improved fire safety and reduced environmental impact. Commonly found in connectors, switches, circuit breakers, and automotive parts exposed to high temperatures. It also shows good compatibility in epoxy resins used in encapsulation and coatings.
