Carbon Rubber Electrodes | Conductive Silicone Pads | TOP-RANK
Professional reusable carbon rubber electrodes for TENS, EMS, and Galvanic therapy. High-flexibility silicone matrix with < 100 Ohm resistance. Compatible with sponge covers and Velcro straps.
Product Overview
Carbon rubber electrodes are non-adhesive, reusable interface components for transcutaneous electrical stimulation. They function as a permanent conductive path, requiring a secondary medium-such as a dampened sponge or conductive gel-and mechanical fixation via elastic straps. These are supplied to B2B physiotherapy clinics and sports medicine centers to reduce the operational cost of disposable hydrogel consumables.
Key Features
-
Volumetric Impedance Consistency
In standard TENS stickers, impedance is concentrated at the thin carbon-ink layer. In carbon rubber electrodes, the current is distributed through a 2mm-thick conductive matrix. This volume-conductive logic ensures a uniform current density distribution (mA/cm2), preventing the "stinging" effect associated with edge-current accumulation in thin-film electrodes.
-
Chemical Inertness and Disinfection
The silicone-carbon bond is chemically resistant to 70% Isopropyl Alcohol (IPA) and chlorine-based disinfectants. This allows for repeated sterilization protocols in high-traffic clinical settings without the material becoming brittle, cracking, or losing its surface conductivity over a 12-24 month service life.
-
Thermal Sink for Galvanic Protocols
In high-voltage or galvanic treatments, thermal buildup at the skin interface is a primary safety risk. Carbon rubber acts as a passive heat sink, dissipating thermal energy generated by the electrical resistance of the skin. This maintains the interface temperature below 41C during 20-minute sessions.

FAQ
Q: Why does the electrode resistance increase after 12 months?
A: This is typically due to surface calcification from tap water used in sponge covers or residue from conductive gels. It is not a depletion of the internal carbon. Sanding the surface lightly with 600-grit sandpaper removes the oxidized layer and restores original Ohm ratings.
Q: How do these perform under IEC 60601-2-10 current density tests?
A: Carbon rubber electrodes maintain a deviation of < 10% in current distribution across the surface when tested at 2 mA r.m.s./cm2. This exceeds the minimum safety requirements for professional-grade stimulators.
