Carbon black is a vital component in making many of the products we use every day strong, appealing, durable and safe. Some of these solutions include tires, automotive weatherstrip and belts, plastic parts, coatings, inks and sealants. For example, tires without reinforcing carbon black would not run over 100 miles. As a pigment, carbon black offers desired color strength for applications ranging from electronic enclosures to automotive coatings, and household appliances. Carbon black imparts UV durability to rubber and plastic goods to ensure their service life for a few decades. As an electrically conductive additive, carbon black renders insulative rubber and plastic materials antistatic, electrodissipative or conductive to provide safety and protection, and thereby reliability for mining, electronic packaging, and wire and cable applications, to name a few.<\/p>\n<\/div><\/div><\/div>
In principle, carbon black can be stored for many years in a dry, cool, and well-ventilated location.\u00a0 According to ATM D 8043 Standard Guide for Carbon Black \u2014 Shelf Life, \u201cthe shelf life of carbon black is defined as indefinite when stored in a manner that protects it from liquid water or high humidity environments. The only two properties of carbon black known to change over time are moisture and Iodine number. The moisture content can change over the short-term (weeks or months), depending on the ambient humidity and the surface area of the carbon black. Iodine number can change over an extended period (years) due to a slow increase in the oxygen content on the surface of the carbon black.\u201d\u00a0\u00a0 However, \u201cthe slight change in Iodine Number over an extended period does not affect actual surface area properties and in-rubber performance of the carbon black.\u201d<\/p>\n<\/div><\/div><\/div>

Below are a few examples: 1) Avoid dust formation; do not breathe dust; provide appropriate local exhaust to minimize dust formation; do not use compressed air; 2) Take precautionary measures against static discharges; 3) Maintain safe work practices, including the elimination of potential ignition sources in proximity to carbon black dust, good housekeeping to minimize accumulation of dust, and appropriate exhaust ventilation design and maintenance to control airborne dust levels, etc.; 4) Handle in accordance with good industrial hygiene and safety practices.5) Use process enclosures and\/or exhaust ventilation to keep airborne dust concentrations 6) Wear appropriate PPEs. e.g., respirators, masks, safety glasses or goggles, protective glove, and clothing, etc.<\/p>\n<\/div><\/div><\/div>
The industry has made tremendous progress in recovering carbon black for re-usage.\u00a0 One of the examples is to reclaim carbon black from post-consumer tires and reuse it for tires or other applications.\u00a0 After years of extensive research and development, Birla Carbon has introduced ContinuaTM<\/sup> Sustainable Carbonaceous Material (SCM) to make circularity a reality.\u00a0 Please visit https:\/\/www.birlacarbon.com\/continua\/<\/a> or contact a Birla Carbon representative for details.<\/p>\n<\/div><\/div><\/div>
