①. Market Background

New developments in automotive, aerospace, national defense, telecommunications, electronics and electrical markets are rapidly driving the demand for various electrostatic discharge (ESD) and electromagnetic Shielding (EMI Shielding). The current solution is to add conductive fillers such as carbon black, carbon fiber, stainless steel fiber, and metal additives to the polymer to realize the conductivity of the polymer. The use of these fillers may lead to problems such as powder dropping, processing difficulties, excessive density and excessive weight of products.

②. Hot Topics

With the development of electronic industry, the promotion of 5G technology and the application of auto-driving technology, higher requirements are put forward for the performance of electrostatic release and electromagnetic shielding materials, such as high strength, light weight and miniaturization. Traditional conductive filler can no longer meet these requirements. For example, in the application field of electrostatic release, when carbon black is used as a conductive additive, the addition amount of carbon black usually needs to reach more than 15wt%. Due to the existence of high content of carbon black, sometimes the product will have the problem of "powder shedding", which will cause the pollution of electronic products and is unacceptable for the packaging of precision electronic products. In addition, high content of carbon black will also affect the mechanical properties of the material, such as toughness, tensile properties, etc. In the application of electromagnetic shielding, the material is often required to have very excellent conductivity, so the content of conductive filler is relatively high. Using a large amount of conductive filler will not only greatly increase the density of the material, at the same time, it will seriously affect drawing abillity.

So, is there a kind of conductive filler that can meet the current demand for high-end electrostatic release and electromagnetic shielding materials?

③. Solution

Cabot's new ATHLOS^TMCarbon Nanostructure (CNS) is a series of unique cross-linked Carbon nanotube materials manufactured by proprietary processes. As Cabot's innovative advanced carbon material solution, ATHLOS^TMCNS can help polymers achieve the best balance of conductivity, mechanical strength and processability, thus it can be widely used in high-end-electrostatic release and electromagnetic shielding fields. In ATHLOS^TMIn the use of CNS, by replacing or reducing the use of traditional conductive filler, the final product can be lightweight, miniaturization, and the mechanical properties of the product can be improved or maintained, reduce or eliminate the problem of powder dropping that may occur when using other fillers. In EMI Shielding applications, ATHLOS^TMCNS can be used independently or in combination with other conductive additives to provide flexible solutions for different application requirements of customers.

In addition, as a nano material, ATHLOS^TMCNS has higher requirements on occupational safety and protection during use. Cabot can provide customers with ATHLOS based on a variety of polymer substrates.^TMCNS masterbatch products. On the one hand, ATHLOS^TMCNS masterbatch products can help customers use this unique nano material more conveniently and safely. On the other hand, based on Cabot's understanding of ATHLOS^TMThe profound understanding of CNS and the masterbatch products developed by rich knowledge of carbon material formulation and processing technology control can help customers achieve better dispersion during use, thus giving full play to ATHLOS^TMExcellent performance of the CNS.
