Fiber Solution Systems Used in Real Manufacturing

Fiber Masterbatches

What it is

A concentrated blend of carbon black dispersed in a polymer carrier, later diluted during fiber spinning.

Why it is used

Controlled dosing
Improved dispersion vs direct addition
Process stability

Common factory problems

  • High pressure drop across filters
  • Masterbatch agglomerates causing breaks
  • Inconsistent fiber color

Key carbon black requirements

Excellent dispersion in polymer melts
Low ash
and impurity content

Minimal impact on melt flow

Stable rheology

ISTAR Solution – AEROVANS® + PLASTEXA®

AEROVANS® (Fiber-Optimized Carbon Blacks)

  • Low-density morphology → lighter fibers
  • Excellent melt dispersion
  • Reduced filter pack pressure
  • Stable spinning at high speeds

PLASTEXA®

  • Optimized compatibility with polymer carriers
  • Predictable rheology in masterbatch systems
  • Clean, consistent processing
  • Low-density morphology → lighter fibers
  • Excellent melt dispersion
  • Reduced filter pack pressure
  • Stable spinning at high speeds
  • Optimized compatibility with polymer carriers
  • Predictable rheology in masterbatch systems
  • Clean, consistent processing

UV retention vs Aging Time + Tensile strength retetion

iStar Carbon Blacks maintain low pressure even as throughput increases

AEROVANS® + PLASTEXA® generate the lowest pressure drop across the filtration system due to superior dispersion
