PU Antioxidant

PU Antioxidant functions by scavenging free radicals and decomposing peroxides formed during PU polymer aging. It prevents yellowing, embrittlement, and loss of elasticity in foam, sealant, and coating systems. Available as hindered phenolic and phosphite types, it ensures long-term color stability. The additive blends easily with polyols and prepolymers and resists leaching or volatilization during processing.
