Conventional Carbon Blacks & Application

Typical choices here are reinforcing and semi-reinforcing furnace blacks:

N220/N330
build modulus for stiffness and support
N550/N660

where slightly lower modulus and better processability are needed

Industry Problems with Conventional Grades

ISTAR Solution – SPIREXA® + DURONIX® Belt Architecture

SPIREXA® reinforces high-stress belt sections (tension zones) with optimized
dynamic properties.

DURONIX® semi-reinforcing grades adjust modulus and flow in compression or
neutral zones.

By combining SPIREXA® and DURONIX®, iSTAR allows belt makers to:
Controlled porosity & surface activity for improved filler–polymer interaction and fatigue life.
High cleanliness and dispersion behavior to reduce crack initiation sites.
Morphology-engineered aggregates for strong reinforcement with lower hysteresis, so mounts run cooler.
Optimised structure density to build modulus without over-stiffening the compound.
