OCSiAl’s graphene nanotubes become the solution for a Chinese silicone rubber compound manufacturer. Graphene nanotubes outperform other conductive materials for silicone rubbers used in skin-contact applications such as carbon black and silver particles.
Nanotubes make it possible to pass massage pulses through rubber to the human body, while maintaining the desired original properties of the silicone.
Ensures Stable Volume Resistivity
A dosage as low as 0.25% of nanotubes from OCSiAl replaces up to 40% of carbon black in a conductive HCR (high consistency rubber) silicone compound, ensuring stable volume resistivity of <100 Ω cm. It shows no carbon release to the material’s surface and no contamination of the skin.
This tiny dosage of strong, highly electrically conductive, and flexible nanotubes does not impair the silicone’s softness or elasticity and makes it possible to maintain other mechanical properties. Developed by OCSiAl, industry-friendly forms of nanotube concentrate based on silicone-compatible carriers allow manufacturers to retain standard production processes, which is not achievable when applying silver-based additives.
The new silicone compound is used in the production of a serial line of electrical devices for massage treatment. Compliance of the nanotube compound with the EU RoHS Directive, along with the fact that OCSiAl’s nanotubes are the only single wall carbon nanotubes registered under the European REACH regulation, has allowed the manufacturer to enter the European market and further expand its line of products using the new nanotube silicone compound.
