Conductive Masterbatch – Reliable Static Control and EMI Shielding for Plastic Products

Conductive masterbatch is a functional concentrate made by dispersing high concentrations of conductive fillers such as carbon black, carbon nanotubes, or graphene into a carrier resin including PE, PP, ABS, PA, and other polymers. It is produced through melt mixing and pelletizing. This product is designed to give plastic products antistatic, conductive, or electromagnetic interference (EMI) shielding properties. As an Electrical Conductivity Additive, it allows electrical charges to flow through the plastic instead of building up on the surface. As a Static Charge Dissipator, it safely drains static electricity to prevent sparks and dust attraction.

How It Works

The conductive fillers form a continuous network inside the polymer matrix. This network provides a pathway for electrical charges to travel, effectively reducing surface and volume resistivity. When the filler loading reaches the percolation threshold, conductivity increases sharply. Our Conductive Masterbatch is engineered to achieve this network at practical loading levels, balancing conductivity with mechanical properties. The carrier resin is selected to match the base polymer, ensuring good compatibility and even filler distribution.

Key Benefits

• Prevents static buildup and dust attraction on plastic surfaces

• Provides reliable static charge dissipation for sensitive components

• Offers electromagnetic interference (EMI) shielding for electronic housings

• Reduces sparking risks in flammable or explosive environments

• Maintains mechanical properties at recommended loading levels

Material Compatibility

Our Conductive Masterbatch is available in multiple carrier resins to match different base polymers, including PE, PP, ABS, PA, PC, and more. This ensures good dispersion and compatibility without compromising the final product's mechanical performance or surface finish. The filler system is selected based on the target conductivity level and processing method.

Applications

• Electronic packaging trays and component carriers

• EMI shielding housings for electronic devices

• Fuel system components and explosion-proof equipment

• Antistatic films and sheets for cleanroom use

• Conductive pipes, tubes, and industrial containers

• Automotive parts requiring static dissipation

Processing and Customization

Our Conductive Masterbatch is easy to process. Simply add the masterbatch at the hopper with the base resin. A standard dosing unit works for most injection molding and extrusion lines. The recommended addition ratio varies based on the target conductivity level and polymer type. Our technical team provides starting points for each application. We also offer customization of filler type, loading level, and carrier resin to meet specific requirements. Packaging is in standard moisture barrier bags. Store in a dry, cool place away from direct sunlight. All products are backed by years of experience in Conductive Masterbatch development for diverse industries.
