Nylon color and heat stabilizer
Added during polyamide polymerization to limit discoloration and improve heat stability.
Фенилфосфиновая кислота (benzenephosphinic acid) is a phosphorus intermediate and a color and heat stabilizer for polyamide, used in nylon polymerization, phosphorus flame-retardant chemistry and dye, pesticide and pharmaceutical synthesis. SUNCHEM supplies it with a batch COA on every shipment.
Phenylphosphinic acid has a reactive P–H bond and an acidic P–OH group on a phenyl ring, which makes it both a mild reducing agent and a useful phosphorus building block. In polyamide production it is added during polymerization as a catalyst and stabilizer that helps nylon keep its color and heat stability. It is also an intermediate for phosphorus-based flame retardants and for dye, pesticide and pharmaceutical synthesis.
