Anti-static agent for electrically conductive liquid silicone rubber (LSR) with retained color and mechanical performance
TUBALL™ graphene nanotubes are a high-performance conductive agent for liquid silicone rubber (LSR), enabling the full range of electrical resistivity <10 to 1010 Ω•cm, while maintaining low viscosity, high operational reliability and permanent elasticity.
With their unique properties, graphene nanotubes, also known as single wall carbon nanotubes, help to avoid any drawbacks in silicones associated with the use of standard anti-static additives.
Conductive silicones with TUBALL™ MATRIX

Full range of resistivity
For compounders’ convenience, OCSiAl has developed the TUBALL™ MATRIX line which features homogeneous dispersion of graphene nanotubes. The extremely low concentration of TUBALL™ MATRIX (which is 3 to 10 times lower than that of carbon black used as an anti-static agent) guarantees no carbon release on the surface of the final products and allows coloration of anti-static LSR compounds.
Nanotube concentrates for LSR silicones feature:
- Reduced filler content to provide the full range of electrical resistivity
- Stable conductive properties during usage
- Excellent processing properties
- Low viscosity, high operational reliability, and permanent elasticity
- Allows coloration of the final compound
LSR silicones with graphene nanotubes have applications in cable shielding, printing and electronics manufacturing, and a wide variety of consumer goods.
Depending on the desired final application, there are two types of nanotube concentrates: TUBALL™ MATRIX based on polydimethylsiloxane oil and vinyl-terminated polydimethylsiloxane as carriers. For more details, click the product cards below, or contact us.
