High-performance anti-static additive for electrically conductive and reinforced fluoroelastomers (FKM)


TUBALL™ graphene nanotubes are a reinforcing and conductive additive for improving the performance of two types of widely used fluoroelastomer formulations: those based on carbon black and those based on mineral fillers. Adding TUBALL™ allows manufacturers of FKM products to enhance the mechanical and aging properties and the durability, and also to provide electrical conductivity.

Highly conductive, super strong and flexible, graphene nanotubes have a record length-to-diameter ratio. These properties allow them to form three-dimensional conductive and reinforcing networks inside rubbers even at extremely low working dosages – starting from hundredths or tenths of a percent of the material’s total mass. The application of TUBALL™ in FKM, which is often used in aggressive environments, provides even more heat and fuel resistance and contributes to electrical conductivity, without affecting the elastic properties or hardness.

Silica-based formulation. Improvement of mechanical properties after aging

Carbon black-based formulation. Improvement of mechanical properties after aging

To simplify the handling of nanotubes and to adapt them to standard industry technological processes, OCSiAl has developed TUBALL™ MATRIX, a versatile masterbatch for fluoropolymers that is compatible with FKM carbon black and silica based compounds.

TUBALL™ MATRIX features for FKM:

  • Freedom in formulation design because of the extremely low loadings of TUBALL™
  • Improved mechanical properties without drawbacks in elasticity
  • Permanent and uniform electrical conductivity
  • Improved mechanical stability after heat/fuel aging
  • Increased durability of the final products thanks to improvements in abrasion resistance, modulus, and tear and tensile strength
  • Maintained rheological properties
  • Standard processing and mixing equipment
  • Retained colors without carbon release to surface for anti-static applications

Graphene nanotube modified FKMs are the top choice for heat-resistant rubber applications in aggressive environments, and can be used in the oil & gas, automotive and chemical industries, as well as in robotic manufacturing, where the combination of color and electrical conductivity are required for identification of parts by robots.
