Application

2-Hydroxy-4-n-octyloxybenzophenone serves as an effective UV absorber designed to enhance the stability and longevity of various materials exposed to sunlight. This light yellow powder is primarily utilized in insulating plastics and organic solar cells, where it acts to enhance stabilization. Its application extends to being incorporated into parylene C films, improving light stability, and potentially serving as a moisture transfer barrier for electronic boards and photovoltaics. As a member of the benzophenone family, it is capable of absorbing UV radiation in the 240-340 nm range, exhibiting characteristics such as light color, non-toxicity, and ease of processing. Notably compatible with a wide array of materials, including polyethylene, PVC, polypropylene, and organic glass, it significantly reduces color fading, delays yellowing, and upholds physical integrity. Additionally, 2-Hydroxy-4-n-octyloxybenzophenone is instrumental in extending the life of industrial polymers and coatings, making it an invaluable component in protecting materials from the deleterious effects of UV exposure.
