Superior conductivity with less filler?

Graphmatech's graphene-based AROS Conductive Compounds deliver superior conductivity with lower filler content than industrial conventional solutions, while supporting PPWR sustainability goals.

Why this matters?

• Easier & faster processing: better flow, lower viscosity, higher throughput
• Equipment & tooling friendly: less wear, clogging, and maintenance
• Better material performance: preserves mechanical properties and surface quality
• Precisely tunable conductivity: more consistent and controlled electrical performance
• Lower total production cost: less filler, lower energy use, and easier scale-up

With our proprietary AROS Conductive Compounds, we achieve ultra-fine graphene dispersion, creating a highly efficient conductive network that enables:

• ESD performance at low loading, evaluated with ANSI/ESD STM11.11 and ANSI/ESD STM11.12
• Works in synergies with other fillers such as carbon black and carbon nanotubes
• Improved or replacement performance versus carbon black masterbatches
• Enhanced barrier properties
• Increased mechanical strength for lightweight designs

Typical applications

• ESD-safe components
• Packaging & Trays
• Cable jackets
• Pipes
• Automotive parts

AROS Conductive Compounds technology allows for a very fine dispersion of graphene and strong polymer-graphene interaction, where the graphene network allows for excellent electrical conductivity at low total carbon content. The high surface area of graphene allows for large improvement of properties at very low additions. As an example. at 100 wt.% masterbatch, a volume resistivity of 1 Ohm cm can be achieved.

Graphene in synergy with other conductive fillers

Graphene also acts in synergy with other carbon fillers such as carbon black and carbon nanotubes, improving polymer properties on the nanoscale and vastly reducing total carbon content. With only 5 wt% graphene-based masterbatch and less than 1 wt% graphene, 10 orders of magnitude less volume resistivity, 5 orders of magnitude less surface resistivity can be achieved.

Volume and surface resistivity of carbon black conductive compound diluted to 50% in HDPE compared to the same diluted compound with addition of only 5 wt% AROS HDPE IM conductive compound. With only 5 wt% graphene-based masterbatch, 10 orders of magnitude less volume resistivity, 5 orders of magnitude less surface resistivity can be achieved.

The volume resistivity was measured on extruded strands according to internal SOP. That method involves applying silver to the extruded polymer strands to eliminate contact resistance. For surface resistance, the SRM110 is equipment that allows determination of whether a material meets the requirements of IEC 61340-5-1 and ANSI/ESD S20.20.
