Product Quality

The quality of our carbon black and our product expertise has a direct impact on the performance and safety of our customers’ own products. As a leading global business focused solely on carbon black production, we are in a strong position to supply our customers with groundbreaking products that are consistently of the very highest quality.

Quality Assurance

Most of our plants are ISO 9001 registered, certifying that we have established and documented methods for our processes. All of our production facilities have a Quality Assurance (QA) laboratory, which uses state-of-the-art equipment to test our products against stringent shipping specifications. These QA laboratories ensure that the material sent to our customers complies exactly with their specific requirements.

Focus on Product Consistency

Birla Carbon customers expect a product that consistently meets the highest quality standards. For carbon black, these standards focus on three key areas:

  • colloidal properties, or those related to the carbon black morphology (microscopic physical characteristics);
  • physical form, referring to the bead quality (size and hardness) of carbon black; and
  • cleanliness, in terms of the purity of our product.

Birla Carbon rigorously tests its carbon black through internationally recognized test procedures and processes. Based on customer requirements, and regular reviews of the correlation between our customers’ laboratories and our own, we define Upper Specification Limits (USL) and Lower Specification Limits (LSL) for each test. Our products only leave our gates if all of the required parameters are tested and the product is certified within these limits.

Our testing processes are validated through a process capability index (Cpk), which statistically measures their reliability. All of our testing equipment in our quality departments are regularly serviced, checked and calibrated to guarantee maximum product quality.

Creating Business Leadership

Business leadership requires the best facilities and processes. Our Research and Development (R&D) activities are based in our centers in Taloja (Maharashtra, India) and Marietta (Georgia, USA), as well as two other regional satellite laboratories in Korea and Brazil. These state-of-the-art technology centers employ more than 50 leading scientists. Our Product Technology group works with our technical service teams throughout the world, and engages daily with our customers to ensure their needs are met.

Working with ASTM

Each of our laboratories receives regular audits from our material analysis group and is assessed twice a year through participation in an international proficiency testing program: the Laboratory Proficiency Rating System (LPRS). This program, organized by the American Society for Testing and Materials International (ASTM International), provides us with an opportunity to internally compare our laboratories with more than 100 centers worldwide. Should any anomalies or deviations be found through this LPRS, we conduct investigations, with support from our two central laboratories. This commitment to sharing best practice ensures our laboratories meet the very highest global standards. 

Birla Carbon actively participates in the  ASTM D24 Technical Committee, which develops internationally recognized and accepted test standards applicable to carbon black. The ASTM standards play a key role for our products in areas such as composition, properties, classification, nomenclature, analysis and quality assurance.
