AR7 is commonly used as a high-performance additive in polymer formulations to enhance thermal stability and UV resistance. It is particularly effective in outdoor applications where prolonged exposure to sunlight and heat can degrade materials. Industries utilize AR7 in coatings, plastics, and elastomers to extend product lifespan and maintain mechanical integrity under harsh environmental conditions. Its ability to quench free radicals and absorb harmful radiation makes it a key component in stabilizing polyolefins and engineering plastics. Additionally, AR7 is favored in automotive and construction materials for improving weatherability without compromising clarity or color.
