Application: Phenylphosphinic acid is a promoter of free radicals and organic peroxide catalysts in polymerization process. It is utilized as a general antioxidant and a color, light and heat stabilizer for polymers especially polyamides. It is an intermediate to form non-ferrous metals used as polymer stabilizers. Phenylphosphinic acid is a powerful reducing agent reacting rapidly with oxidizing agents.
