Ultraviolet absorber is one of many additives. One of its functions is to prevent the damage of ultraviolet rays to products. UV absorbers are also used by various manufacturers in all aspects, especially in the summer. The ultraviolet radiation in the air is also doubled. The growth of our products has a certain impact on our lives and articles. If we want to protect ourselves from sunscreen, the articles need to be protected naturally, otherwise ultraviolet rays will cause damage to the molecular structure of the product, resulting in accelerated fading, yellowing, and aging. The use of UV absorbers is very important at this time. Although UV absorbers can solve problems well, there are many types on the market, and the selectivity is also multi-faceted. It is not that a UV absorber can be applied. For all products.
Usually, we use ultraviolet absorbers while adding some auxiliary agents such as antioxidants to assist, because the traditional ultraviolet absorber is a single effect, only plays the role of ultraviolet protection, and can not be Solving problems in many ways is more troublesome to use in this way, and these require repeated experiments and an additive effect of multiple additives, and more and more problems will be considered. For example, whether multiple additives used at the same time will cause a chemical reaction that will affect the essence of the product and affect the effect. This is a problem that each manufacturer will consider and relatively pay attention to.
