Conventional Carbon Blacks & Application

Commonly:
N660/N772

type blacks for soles, as they give reasonable softness and wear

Some use thermal black blends to soften compounds.

Industry Problems with Conventional Grades

  • Standard blacks can raise hardness more than desired, making soles less comfortable.
  • Dispersion issues cause specks, streaks or flow marks on visible tread.
  • PAH and odor concerns in contact applications

ISTAR Solution –
PLASTEXA® + DURONIX®

PLASTEXA® soft-rubber black series

  • Larger particle, low structure design for softness and comfort feel.
  • Easy dispersion → clean tread patterns, no specks.
  • Lower hardness rise at target phr.

DURONIX® non-reinforcing / thermal-type variants

  • Further soften compounds, reduce heat buildup and improve flexibility in thicker soles.
  • Larger particle, low structure design for softness and comfort feel.
  • Easy dispersion → clean tread patterns, no specks.
  • Lower hardness rise at target phr.
  • Further soften compounds, reduce heat buildup and improve flexibility in thicker soles.

Result: Soles with better comfort, cleaner appearance, controlled hardness and improved wear, engineered through carbon black choice.
