- Grade Name: Carbon Black EMP70
- Competitor’s grades: HiBlack 50L,Monarch/BP700,MCF 88,Raven 2350/2300/2000 Ultra
- Appearance: Powder
- Expiration Date: 3 years from manufacturing date
Performance feature
- 19 nm particle size with 185 m²/g surface area→ Finer and darker than EMP60, delivering deeper and cleaner black tones
- Tint strength 142% (high level)→ Stronger color output; ideal for PU coatings, masterbatch, and printing inks
- Low structure (DBP 50 ml/100g)→ Very easy to disperse with low system viscosity, suitable for demanding processes
- pH 3.5 (slightly acidic)→ Excellent compatibility in PVC, PU, water-based systems, powder coatings, and inks
- Low volatile (1.5%) + ash 0.30%→ Stable appearance with consistent blackness
- PAHs ≤10 & heavy metals ND→ Fully compliant with environmental and safety standards
Why Choose it
EMP70 provides higher jetness and stronger tinting than EMP60 while maintaining smooth dispersion and broad compatibility — an excellent value-for-performance choice for customers demanding deeper blackness.
Recommended Application
- PVC cable coloring, PU Coatings, Masterbatch, water based paste,
- Powder Coating, solvent based printing inks
