Chinese name: Aluminum diethylphosphinate

Foreign name: Aluminum photoshinate/DEPAL

Purpose

Aluminum diethylphosphinate is used as an excellent halogen-free flame retardant for engineering plastics, such as polyamide, polyester, thermosetting plastics, and elastomers. In terms of UL94 flammability testing, Glow Wire Ignition Temperature (GWIT), Glow Wire Flammability Index (GWFI) testing, and Leakage Traceability Index (CTI), aluminum diethylphosphinate exhibits excellent performance in glass fiber reinforced polyamide 6 and 66 composites, as well as various polyesters (PBT and PET).

Aluminum diethylphosphinate can not only play a role in the condensed phase, promoting polymer carbon formation, but also remove high-energy free radicals in the combustion zone. Aluminum diethylphosphinate is often used in combination with other halogen-free flame retardants or synergistic agents, such as melamine polyphosphate and melamine cyanurate.

Aluminum diethylphosphinate has both environmental and health friendly properties.
