Black Cat details recovered carbon black advances for tire applications

Jining, China – Jiangxi Black Cat Carbon Black has reported progress in developing recovered carbon black (rCB) for tire applications, highlighting improved material performance and certification of its Jining production facility.

In a 21 Oct announcement, the Chinese producer said its rCB production process included multi-stage magnetic separation, ultrafine grinding and granulation to improve purity, dispersion and handling.

The company said it had reduced ash content to 15–18%, compared with 18–22% for conventional industrial-grade pyrolysis carbon black.

In comparative tests using SBR/BR rubber compounds, Black Cat reported lower heat build-up and higher resilience than selected conventional carbon black grades.

Separately, the company said it was using pyrolysis oil recovered from waste tires to partially replace coal tar in furnace carbon black production, producing 'sustainable carbon black'.

Black Cat also confirmed that its Jining facility obtained ISCC+ certification in September, becoming its third certified production base after its headquarters and Tangshan operation.
