In general, the destruction of the molecular structure and, as a result, the reduction of the useful life of many polymer products by the ultraviolet spectrum of sunlight has always been considered as a limiting phenomenon in the use of polymer products that are in direct proximity to sunlight. Although a wide range of light stabilizers from the HALS family and light absorbers have been commercially produced and supplied to international markets in the last few years, due to the diversity of parameters affecting the mechanism of the light degradation phenomenon, such as the type of polymer, the conditions of the product production process, the climatic conditions of the consumption environment, the consumption rate and thickness of the product, and even the cost, the selection of the appropriate light stabilizer additive package for each product is of great importance. Pooy Polymer Tehran Company has succeeded in providing its customers with a wide range of UV stabilizer masterbatches by gaining sufficient experience in designing and selecting the appropriate light stabilizer for various production applications, at reasonable prices, and under the brand name POOYAD UV.
