Antioxidant 1010, also known as Pentaerythrityl Tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate], is a primary antioxidant compound that belongs to the class of hindered phenols or phenolic antioxidants. It is widely used in various industries to prevent the degradation of materials caused by oxidation. Antioxidant 1010 works by scavenging free radicals and inhibiting oxidation reactions. It acts as a hydrogen donor, neutralizing free radicals by providing a hydrogen atom to stabilize them. This process helps prevent the degradation of materials and extends their lifespan. Antioxidant 1010 is widely used in various industries, including plastics, polymers, coatings, rubber, adhesives, lubricants, and food packaging, to improve stability, prevent degradation, and extend the lifespan of materials. It protects against oxidative damage, enhances resistance to aging, and maintains the quality and performance of products under harsh environmental conditions.
