The Factory Supply Optical Brightener OB-1 with CAS number 1533 - 45 - 5 is a high - quality optical brightening agent. It has a fine white to yellowish - white crystalline powder appearance. The product is well - known for its excellent optical brightening effect and stability.
Key parameters include a high melting point, which ensures its performance under high - temperature processing conditions. Its purity is usually above a certain standard, which guarantees its effectiveness in various applications. The solubility of Optical Brightener OB - 1 is also an important parameter. It has a certain solubility in some organic solvents, which is beneficial for its uniform dispersion in different media.
Optical Brightener OB - 1 has a wide range of uses. In the plastics industry, it is widely used in polyesters, polyamides, and polyolefins. By adding Optical Brightener OB - 1 to plastic products, the yellowing of plastics can be effectively reduced, and the whiteness and brightness of the products can be improved. This makes plastic products look more attractive and of higher quality, especially for white or light - colored plastic items such as plastic household appliances, plastic packaging materials, etc.
In the textile industry, it can be used in the finishing process of synthetic fibers. It enhances the whiteness and luminosity of the fibers, making the textile products more vivid and eye - catching. It is also suitable for the paper industry. When added to paper pulp, it can increase the brightness of the paper, improve the visual quality of printed materials, and is very useful for high - grade paper such as coated paper and white cardboard.
When using Optical Brightener OB - 1 in the plastics industry, first, determine the appropriate dosage according to the type of plastics and the desired effect. Usually, the dosage is in the range of 0.01% - 0.1% of the plastic resin weight. Mix the brightener with the plastic resin thoroughly before the plastic processing (such as extrusion, injection molding). Make sure to use appropriate mixing equipment to ensure uniform dispersion.
In the textile industry, dissolve the Optical Brightener OB - 1 in a suitable solvent first. Then, add the solution to the dyeing or finishing bath. Adjust the concentration of the brightener solution according to the fabric type and processing requirements. For the paper industry, add the brightener to the paper pulp during the pulping process. Stir well to ensure uniform distribution in the pulp.
Plastic Case: A plastic product manufacturer planned to produce a series of white plastic storage boxes. They added Optical Brightener OB - 1 to the polypropylene resin at a dosage of 0.05%. After the injection - molding process, the storage boxes showed significantly improved whiteness and brightness compared to the products without the brightener. The surface of the boxes was more uniform in color, and the overall appearance was more appealing, which led to an increase in customer satisfaction and sales.
Textile Case: A textile factory was processing polyester fabrics for high - end clothing. By using Optical Brightener OB - 1 in the finishing process, the polyester fabrics became much whiter and more lustrous. The clothing made from these fabrics had a better market reception. Customers were attracted by the bright and clean appearance of the clothing, which helped the factory gain a competitive edge in the market.
Paper Case: A paper mill was producing coated paper for high - quality magazines. Adding Optical Brightener OB - 1 to the paper pulp at an appropriate dosage resulted in paper with higher brightness and better printability. The magazines printed on this paper had clearer images and more vivid colors, which enhanced the reading experience for consumers and satisfied the requirements of magazine publishers.
