Industry Problems

Fundamental Requirements From Carbon Black

Medium particle size Prevents cell plugging
Low structure Low viscosity, fast drying
Oxidized surfaces Avoid cell scratches
Clean morphology For premium packaging
Stable undertone Smooth film

What Carbon Black Must Deliver 

How ISTAR Series Solve It

NOBLEX®
Engineered for offset rheology
ONYX GEMS®
Engineered for offset rheology
EMPIREX®
Fast-wetting oxidized blacks for faster milling
Product Name Product Description Datasheet SDS
NOBLEX® A balanced-structure carbon black series optimized for rheology stability, gloss control and tint consistency in printing ink systems. It supports reliable flow and colour consistency during long production runs.
ONYX GEMS® An ultra-fine, gas-black–inspired carbon black series offering very high jetness, narrow particle size distribution and strong UV absorption. Designed for applications requiring deep optical density, blue undertone and uniform appearance at lower pigment loadings.
EMPIREX® A furnace carbon black series delivering balanced reinforcement, controlled rheology and reliable dispersion across coatings, plastics, rubber and inks. It provides stable colour strength, manageable viscosity and consistent processing, prioritising formulation robustness over extreme jetness or conductivity.
