As a traditional effective antioxidant additive, UV531 has been occupying a position in the market. UV531 can absorb UV light in 240-340nm, and has the characteristics of light color, non-toxic, good compatibility, low mobility and easy processing. It has the greatest protective effect on the polymer and helps to reduce the discoloration, while delaying yellowing and retarding the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, organic glass, polypropylene fiber and ethylene vinyl acetate, etc. It can also provide excellent light stability for dry phenolic and alkyd varnishes, polyurethanes, acrylates, epoxy resins and other air drying products and automobile finishing paints, powder coatings, polyurethanes and rubber products.
Due to the outbreak of resorcinol, the main raw material of UV531, in previous years, its production cost increased significantly. However, the emergence of new domestic raw material suppliers has not greatly alleviated this situation. In view of this situation, our company has been actively providing new substitutes for customers as early as 2018 and promoting UV531S uv absorber to the market based on the performance and application of UV531.
UV531S is a kind of light yellow powder, which can completely replace UV531 products on the market at present. It can be replaced by 1:1 when used as high-energy additive in PE, PP and PVC plastics.It can provide excellent color protection effect in PVC during the long-term UVA test, suitable for soft and hard PVC material.For example ,UV531S could replace UV531 in PVC calendering film and louver, and has a excellent effect better than UV531, it also can improve the weather resistance effect of PVC products. Most importantly, the raw material is not restricted by resorcinol, the supply is stable and the price is lower than UV531.
After two years of market promotion, most of our customers have already chosen OMNISTAB UV531S which with the same effect and lower cost. The final product has also been recognized by customers, which has greatly helped customers to reduce production costs.
