- Grade Name: Carbon Black EMP129
- Competitor’s grades: Nerox 605,HiBlack 20L,SB550,Regal 660/660R,#45L#44,Raven 1250/1200
- Appearance: Powder
- Expiration Date: 3 years from manufacturing date
Performance feature
- 25 nm particle size with 124 m²/g surface area→ giving softer jetness but more stable dispersion→ Ideal when deep black is needed without overly high viscosity
- Tint Strength 128% (high level)→ Strong coloring ability, suitable for masterbatch and coatings
- DBP 60 ml/100g (medium structure)→ better gloss and higher color intensity→ Provides stronger film strength and uniform appearance
- pH 3.0 (slightly acidic)→ Offers good compatibility with resin systems such as coatings, pastes, and spinning applications
- Low volatile (1.5%) + ash 0.30%→ Ensures clean color and minimal impurities for high-quality applications
- PAHs ≤10 & heavy metals N.D.→ Meets strict environmental requirements for sensitive industries
Why Choose it
- EMP129 is designed for applications needing balanced jetness, strong tinting, smooth dispersion, and stable viscosity control.
- It offers excellent gloss, uniform film appearance, and universal compatibility, making it a reliable alternative to multiple well-known competitor grades.
Recommended Application
Masterbatch, water based paste, wet spinning paste,
Industry Coating, powder coating, solvent based printing inks.
