Industrial & Automotive Hoses

Used in

Coolant hoses (EPDM, blends)​

Air intake hoses​

Fuel hoses (NBR, HNBR, FKM blends)

Hydraulic hoses and chemical hoses​

Conventional Carbon Blacks & Application

Hose manufacturers typically use:

N550/N660 type semi-reinforcing blacks for EPDM coolant hoses and general hoses
N772 and thermal blacks (N990-type) where flexibility and low heat build-up are needed
Conductive blacks for fuel and ATEX-exposed hoses

Industry Problems with Conventional Grades

  • Semi-reinforcing blacks can increase viscosity, causing processing issues in thickwall hoses
  • Standard thermal blacks can be inconsistent in cleanliness and dispersion behavior.
  • Achieving conductivity in fuel hoses often demands high black loading, which hurts flexibility and fatigue life.

ISTAR Solution – DURONIX® + DURONIX® T + VELCROX®

DURONIX® semi-reinforcing furnace blacks

  • Large particle, ultra-low structure.
  • Low heat build-up, low viscosity, high flexibility.
DURONIX® T thermal-type blacks
  • Large particle, ultra-low structure.
  • Low heat build-up, low viscosity, high flexibility.
  • Ideal for sections that must flex repeatedly without hardening.
VELCROX® conductive furnace blacks
  • For fuel and ATEX hoses.
  • Designed to reach percolation at lower phr, preserving hose flexibility and fatigue resistance.
  • For EPDM and general hoses
  • Balanced modulus, easier extrusion, smooth internal  surfaces.
  • Large particle, ultra-low structure.
  • Low heat build-up, low viscosity, high flexibility.
  • Ideal for sections that must flex repeatedly without hardening.
  • For fuel and ATEX hoses.
  • Designed to reach percolation at lower phr, preserving hose flexibility and fatigue resistance.
Result: hose systems where dimensional stability, flexibility, conductivity and smooth processing are all controlled through precise black selection, not trial-and-error.
