Used primarily as an antioxidant and stabilizer in the production of plastics, particularly in polypropylene and polyethylene resins. It helps prevent degradation from heat during high-temperature processing, making products resistant to discoloration and maintaining good molecular weight retention.

Commonly used in the plastic film, surface coating, and pipe manufacturing industries, as it extends the service life of products when exposed to sunlight and heat.

Additionally, used as a performance enhancer in lubricating oils and specialty lubricants to prevent oxidation and reduce corrosion in machinery.
