GB/T 15339 - 2008 Focus on the identification of carbon black in nitrile rubber. The standard system provides a complete set of specifications from sample preparation, mixing process to performance testing. Through the detection of carbon black in nitrile rubber vulcanization characteristics, physical performance changes and other aspects, accurately judge the suitability of the two. Provide a unified identification method for nitrile Rubber manufacturers and related R & D units to help screen high-quality carbon black, optimize formula design, improve nitrile Rubber mass, and promote the standardized application of carbon black in the field of nitrile rubber and industrial progress.
