Conventional Carbon Blacks & Application

Traditionally:
N550/N660
semi-reinforcing blacks are used in profiles and seals
Non-reinforcing/thermal blacks are used where softness is critical

Industry Problems with Conventional Grades

ISTAR Solution – EMPIREX® + DURONIX® Precision Mix

EMPIREX®

furnace blacks provide moderate reinforcement + excellent flow for efficient extrusion and molding.

DURONIX®

non-reinforcing / thermal-type variants allow softness and controlled compression set without sacrificing cleanliness.

Together, they allow OEMs to:
tune hardness and compression set precisely maintain smooth surfaces and perfect edges in profiles run longer campaigns with lower tool wear

Product Name Product Description Datasheet SDS
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.
DURONIX® A low-structure, ultra-clean carbon black series designed to improve flow, dispersion and surface quality. It supports smooth processing and reduced defects in films, molded parts, hoses, seals and cable compounds.
