Conductive fillers are materials that improve electrical and thermal conductivities. They are primarily used in electronic devices. Conductive fillers are available in various sizes and shapes. They are generally used for EMI (electromagnetic interface) shielding and RFI (radiofrequency interface) shielding. Effective heat dissipation plays an important role in enhancing the performance and reliability of packaged devices. Highly conductive fillers are preferred in applications such as electrodes, conductive wiring, and electrical contact materials. Conductive fillers can also be employed in composites. Commonly used conductive filler materials include silver, copper, nickel, carbon black, synthetic graphite particles, and carbon fiber. Properties of conductive fillers include high electrical conductivity and mechanical strength. Conductive fillers are primarily available in powder form. They can transfer either heat or electricity. Nickel powders and copper powders had significant market share in the global conductive fillers market. However, the trend has been changed with the introduction of products such as composite powders and nickel coated graphite.
Based on type, the conductive fillers market can be bifurcated into metallic and non-metallic. In terms of product, the global conductive fillers market can be segmented into silver, copper, nickel, carbon black, graphite, and carbon fibers. Based on application, the conductive fillers can be divided into coating inks, adhesives, tapes, EMI gaskets, elastomers, and sealants. In terms of end-user industry, the conductive fillers market can be classified into automotive, consumer electronics, aerospace & defense, and others.
Demand for conductive fillers in EMI shielding applications has been rising across the globe. Electromagnetic interference can disrupt electronic devices, equipment, and systems that are used in medical, military, and aerospace electronics industries.
