Overview
ALKANOX™ 240 Powder is a highly efficient organophosphate antioxidant that effectively reduces peroxide-induced oxidative degradation while processing polymeric materials and thermoplastics. This phosphite antioxidant additive carries a broad range of FDA approvals for use in food contact applications.
ALKANOX™ 240 Powder is a cost-efficient phosphite antioxidant for use in high-temperature processes due to its low volatility and superior color control and protection. ALKANOX™ 240 Powder is a commonly used polypropylene for its minimal LTHA color and gas-fading properties. It is also a preferred antioxidant for polyolefins, polycarbonate, ABS, and polyesters when thermal stability and color protection are required. Furthermore, this grade is a general-purpose phosphite process stabilizer for coatings, hot-melt adhesives, and sealants.
