Antioxidants and UV protectors for plastics are suitable for a wide range of applications, including vinyl paints, polyolefins, PU, and textiles. Antioxidants, as the name suggests, prevent oxidation and subsequent yellowing of products; they are typically recommended for finished products that are continuously exposed to outdoor conditions. UV protectors, on the other hand, act differently, protecting the product from the sun's UV rays and other light sources. Oxidation and light degradation are distinct processes, so both types of additives can be used together to extend the product's service life.
Many products may require antioxidants and UV protectors for plastics, such as road signs, window profiles, garden fences, exterior decorations, chairs, and more. Additionally, it is important to highlight that these additives help preserve the material's physical properties, not just its appearance.
It is usually a common grade found in general-purpose formulations with a UV protection Acceptable. It's a neon powder that, when added to plastic parts or paints, helps delay yellowing from UV exposure. Different grades are available depending on the application.
It is recommended to use it with antioxidants, as this type of product is susceptible to oxidation. Similarly, the use of pigments that act as UV filters can improve the performance of your products and reduce costs.
It generally provides greater UV protection and oxidation resistance than benzophenone. It is used in combination with a phenolic antioxidant or a HALS when improved performance is required. The various grades available allow its application in many of the polymers used today.
It is recommended to use it in conjunction with additives that are light-sensitive and can generate chromophores, which results in the yellowing of your pieces.
As its name suggests, it slows down the oxidation of finished outdoor products. It is available in medical grades and general-purpose grades. It provides good initial color, transparency, and gloss to plastics.
Although thermal stabilizers are responsible for preventing product yellowing, these antioxidants are used to provide improved initial color performance during processing, as well as under outdoor exposure conditions.
Phenolic and propionate grades are available for different plastics.
