Carbon Black Content Tester – Analysis by pyrolysis and gravimetry according to IEC 60811-4-1, ASTM D 2671, ISO 6722

ZONSKY's Carbon Black Content Tester helps manufacturers verify material composition and optimize compound formulations for demanding industrial use.

Product applications: Measures critical material parameters, including thermal stability and how evenly the carbon black is dispersed. Ideal for checking raw material quality destined for high-stress automotive, electrical, and industrial components. Provides precise, repeatable data to help engineers refine material recipes and guarantee compliance with global standards.

Key features: Uses advanced analytical testing through reliable pyrolysis and gravimetric analysis to accurately quantify the carbon black percentage in plastics and rubber.

Complies with standards: IEC 60811-4-1:2004, ASTM D 2671, EN 60811-4-1, ISO 6722, BS 7870-3.
