ASTM International approves new standard for recovered carbon black
As per the recent press release, a newly approved standard from ASTM International’s recovered carbon black committee (D36) provided a test that will help to differentiate products and provide a quality control tool for producers and users. Recovered carbon black (rCB) is a recycled product made from end-of-life tires. The new standard, which will shortly be published as D8474, specifies a thermogravimetric (TGA) technique for determining the amount of organic residue, how much fixed carbon is in total, and how much ash is in recovered carbon black.
