Cable industry

Cable & Wire Compounding

The cabling industry requires highly stable, homogeneous and precisely formulated polymer compounds to ensure electrical insulation, mechanical resistance and long-term durability of cables and wires.

Modern cable compounds must meet stringent requirements:

• controlled electrical properties

• uniform filler and additive dispersion

• consistent melt flow behavior

• high surface quality

• strict process repeatability

Even small variations in compounding quality can lead to defects, performance losses or production instability during cable extrusion.

ICMA solution

ICMA develops high-performance twin-screw extrusion lines for cable compound production, designed to ensure maximum formulation control and repeatability.

The co-rotating twin-screw technology allows:

• intensive dispersive and distributive mixing

• precise incorporation of fillers, stabilizers and additives

• excellent temperature control along the process

• stable processing of highly filled formulations

Thanks to the modular screw design, ICMA systems can be optimized for:

• insulation compounds

• sheathing compounds

• halogen-free flame-retardant (HFFR) materials

• PVC, PE, XLPE and specialty cable compounds

Key advantages

• consistent compound quality

• reduced material degradation

• improved electrical and mechanical performance

• high productivity with full process control

Why ICMA

ICMA combines deep process engineering know-how with flexible extrusion technology.

Each compounding line is designed according to:

• compound formulation

• target cable application

• downstream processing requirements

This ensures reliable, repeatable and industrial-grade solutions for the most demanding cabling applications.

Processes and formulations for this industry can be developed and validated on ICMA Lab & Pilot extrusion systems before being transferred to full-scale production lines.
