DPBQ is widely used as a polymerization inhibitor in the production of synthetic resins and plastics. It effectively prevents premature polymerization during storage and processing, ensuring stability and quality of the final product. Additionally, it serves as an antioxidant in lubricants and fuels, protecting them from oxidative degradation and extending their lifespan. In the rubber industry, DPBQ is utilized to enhance the durability and performance of rubber products by preventing degradation caused by heat and oxygen. Its application in adhesives and coatings also helps improve their shelf life and performance under various environmental conditions.
