Optical Brightener Masterbatch<\/p>\n

Generally, the appearance of a product is very important. The tendency of many plastic materials to yellow is due to degradation by UV or visible light\/Processing. The breakdown products absorb blue light, giving a yellow appearance in daylight which giving them a color that negatively affects their appearance.<\/p>\n

Optical brighteners (OBAs) are additives that alter the visual properties of polymers and cause to improve the color of various plastics and can enhance the appearance by making it appear cleaner, brighter and whiter. They mask inherent yellowness in discolored polymers and impart unique, robust color to speciality plastic products. Optical brightener work via a fluorescent mechanism which absorb light in the ultraviolet range and emit light in the ultraviolet blue spectrum. Thus, on a white substrate that has been treated with an optical brightener appears to be \u201cwhiter\u201d than the original untreated material.<\/p>\n

Basta polymer iranian optical brightener masterbatches with Bebright\u00ae brand name, are produced with specific formulations. These masterbatches have good fluorescent whitening effect and increase visual quality of polymers followed by reduce yellowing and opacity of surfaces.<\/p>\n
