Carbon Nanotube (CNT) Conductive Additives for Polymer Processing

Advanced Conductivity at Low Loading Levels

Carbon nanotube (CNT) conductive additives enable polymers to achieve reliable electrical conductivity while preserving mechanical properties, processability, and lightweight design. Compared with traditional conductive fillers, CNTs form efficient conductive networks at significantly lower loading levels, making them ideal for high-performance and functional polymer applications.

Why CNT Conductive Additives?

CNTs feature a unique one-dimensional structure with extremely high aspect ratio, allowing rapid formation of percolation networks within polymer matrices. This translates into stable electrical performance with minimal impact on material properties.

Key advantages include:

• Ultra-low percolation threshold

• High electrical conductivity at low filler loading

• Excellent mechanical property retention

• Stable conductivity under deformation and thermal cycling

• Long-term environmental and electrical stability

CNT conductive additives are well suited for applications where performance, durability, and lightweight design are critical.

Typical Applications

CNT conductive additives are widely used across multiple polymer-based applications, including:

• ESD (Electrostatic Discharge) Protection
  Housings, trays, packaging, and precision components

• EMI Shielding
  Electronic enclosures, automotive electronics, communication devices

• Conductive & Heating Components
  Joule heating elements, temperature control parts

• Sensors & Smart Components
  Strain sensors, pressure sensors, functional polymer parts

• Lightweight Conductive Plastics
  Automotive and industrial components requiring weight reduction

Performance Advantages Compared to Traditional Fillers

CNT-based systems often enable lower total system cost by reducing filler loading, improving durability, and extending component lifetime.
