Used in:

HDPE/XLPE cable sheaths

Automotive wiring

Outdoor cables

Telecom cables

Conventional Carbon Blacks Used Today

Cable producers typically use:

N550/N660

for general sheathing

N772/N990

for improved flow

High-surface pigment blacks for UV protection

Industry Problems with Conventional Grades

  • Rubber-grade blacks cause melt fracture at high extrusion speeds
  • High viscosity → pressure spikes in extruders
  • Poor dispersion → weak spots in insulation
  • Grit & contamination → die wear and surface defects
  • UV lifetime inconsistency outdoorss

Rubber blacks cannot maintain the dispersion + UV + smoothness trifecta.

ISTAR Upgrade — DURONIX® + PLASTEXA® + ONYX GEMS®

PLASTEXA® is engineered specifically for safe, compliant plastics:

DURONIX®

  • Low-grit, low-structure morphology → stable extrusion pressure
  • Smooth sheaths with fewer defects
  • Ideal for XLPE/HDPE insulation

PLASTEXA®

  • High-cleanliness blacks → low contamination risk
  • Protects die tooling
  • Ensures uniform insulation thickness

ONYX GEMS®

  • High jetness with strong UV protection
  • Long-term outdoor durability

ISTAR turns cable blacks from a commodity to a UV-engineered, extrusion-stable material.
