High Efficiency Conductive Plastic Material Pellets For ESD Application

Our experience with carbon black processing translates very well to conductive applications. We offers conductive compounds and masterbatches utilizing a variety of conductive carbon blacks and other additives. Carbon black selection is critical when designing a conductive thermoplastic compound. Depending on which polymer base and end use properties are required, certain types of carbon black may or may not be suitable for consideration.

Conductive carbon blacks can be used as fillers to transform insulating plastics into permanently semiconducting materials. These conductive compounds offer the best price/performance ratio.

Optimal balance between conductivity, physical properties, and processability can be achieved using 5%–50% of carbon black depending on the resin system and the grade of carbon black. Additional benefits include resistance to UV radiation and oxidative degradation.

The conductive grades of carbon black are all characterized by small primary particle size, large surface area, high structure (interparticle agglomeration and branching), and a surface with low oxygen containing groups.

Typically, for a specific polymer system, the conductivity increases with

• Decreasing particle size
• Increasing surface area
• Increasing structure
• Decrease in the number of oxygen containing surface groups like -CO, -COOH, etc. of the carbon black.

The properties of the polymer system that affect the conductivity of a polymer-carbon black system are:

• The interfacial adhesion between the polymer and carbon black
• The crystallinity and crystallization characteristics of the polymer
• The morphology in case of alloys and co-polymers
• The inherent resistivity of the polymer

Moreover, the processing method, rheology, and the extent of carbon black dispersion in the polymer affect the conductivity of these compounds. These classes of compounds are widely used in:

• Packaging for static sensitive electronic and explosive devices
• Antistatic flooring and sheeting for hospitals, semiconductor industry, and mines
• Antistatic belting, hoses, and molded components for automotive, mining and electronics industry
• Power and telecommunications cable sheathing and shielding applications
