UV Absorber

UV absorbers are chemical additives that are used to protect materials from the harmful effects of UV radiation. UV radiation can cause a wide range of problems, including degradation of the material, color fading, and loss of mechanical strength. UV absorbers work by absorbing UV radiation and converting it into heat, which reduces the amount of UV radiation that reaches the material.


UV absorbers are commonly used in a variety of products, including plastics, coatings, and textiles. They are often used in outdoor applications, such as automotive parts, building materials, and sporting equipment, where the material is exposed to UV radiation for extended periods of time.

There are several different types of UV absorbers, including benzophenones, benzotriazoles, and triazines. Benzophenones are one of the most commonly used types of UV absorbers, and they are effective in a wide range of polymers, including polyolefins, PVC, and polyurethanes. Benzotriazoles are often used in coatings and textiles, while triazines are used in polyolefins and other polymers.

UV absorbers can be used alone or in combination with other additives, such as hindered amine light stabilizers (HALS), to provide enhanced UV protection. The choice of UV absorber will depend on the specific application requirements, including the type of material, the level of UV exposure, and the desired level of protection.

It is important to use UV absorbers responsibly and to consider the potential health and environmental impacts of their use. Some UV absorbers have been shown to be toxic or have negative environmental impacts, so it is important to choose the appropriate UV absorber and to use it in a responsible and sustainable manner.
