Polyurethane is an important polymer material, and its excellent physical and chemical properties are widely used in industry and daily life. However, the structure of polyurethane materials is instability because it contains amino groups that are easy to be oxidized and yellowed and unsaturated bonds that are easy to be destroyed by ultraviolet light, it is easy to produce colored substances, yellowing and discoloration when affected by light, high temperature, oxidation, etc., so polyurethane products are very easy to yellowing during processing and storage.
For polyurethane, the conventional antioxidant is not work so good, however the anti-yellowing agent HN-150 performance well and play an excellent anti-yellowing effect in polyurethane. Furthermore, OMNSIATB HN-150 has a good absorption of nitrogen oxides, which can effectively prevent the yellow problem caused by nitrogen oxides on the polymer surface.
The conventional particle size of HN-150 on the market is about 80 mesh, which is very suitable for the spandex spinning industry with a very high cost performance, but due to its compatibility and particle size problems, HN-150 is limited to be used in the polyurethane foam. In order to further expand the application range of HN-150 and meet the needs of more customers, Deltachem has upgraded and improved the production process of HN-150, and the minimum particle size of ultra-fine powder can reach 160 mesh. At present, OMNISTAB HN-150 ultra-fine powder can be commercially provided.
Compared with the conventional HN-150, OMNISTAB HN-150 ultra-fine powder has a finer particle size which can improve its solubility in polymers and solvents, significantly accelerate the dissolution rate in solvents, improve production efficiency, and improve its use effect. After further research and exploration, OMNISTAB HN-150 ultra fine powder has been successfully used in the polyurethane foam industry with efficient anti-yellowing effect while reducing the cost of polyurethane foam.
