ANOX™ PP18 Powder is a high–molecular weight hindered phenolic antioxidant that effectively protects against polymer degradation during processing and long-term aging.
ANOX™ PP18 stabilizer effectively reduces oxidative degradation of most polymers during processing and end-use applications. Because of its low volatility, excellent extraction resistance, and scorch protection, it is ideal for use in polyurethane foams, TPU, spandex, and PU coatings. ANOX™ PP18 is a solid phenolic antioxidant for polyurethane formulations that provides excellent scorch protection and stability at room temperature.
