Product Overview
ALKANOX™ 240 Granular, similar to ALKANOX™ 240 Powder, is a highly efficient phosphite antioxidant that effectively reduces peroxide-induced oxidative degradation during the processing of polymeric materials and thermoplastics. It carries a broad range of FDA approvals for use in food contact applications.

ALKANOX™ 240 is a cost-efficient general purpose antioxidant for use in high-temperature processes due to its low volatility and superior color control and protection.

ALKANOX™ 240 is commonly used polypropylene for its minimal LTHA color and gas fading properties. It is also a preferred antioxidant for use in polyolefins, polycarbonate, ABS, and polyesters when thermal stability and color protection are required. It is also used as a general propose process stabilizer in coatings, hot-melt adhesive, and sealants.
