TENS Replacement Gel Pads | Blue Film Carrier | TOP-RANK Factory
3-layer replacement gel sheets for wire-free TENS/EMS. High-cohesion ionic hydrogel on a PET release liner. No residue, stable impedance.
The Product Interface
These are 3-layer hydrogel sheets designed for snap-on TENS units and EMS belts where the gel handles the entire electrical load. This is a wire-free, carbon-free design. It's a high-frequency consumable for B2B clinical suppliers and home-care brands who need a gel that doesn't turn into a "mushy" mess after three uses.
Critical Performance Points
The Cohesion Factor
Most cheap replacement gels leave residue on the user's skin. That's a failure in polymer cross-linking. We use a high-cohesion formula so the gel stays bonded to the blue carrier film. When you peel it off, it comes off in one piece. No sticky cleanup for the patient.
Ionic Conductivity (Direct Path)
Without a carbon layer, the hydrogel is the only path for the pulse. If the water-to-electrolyte ratio is off, the impedance spikes as the gel dries. We buffer this formula to maintain low resistance even after 20 sessions.
pH Neutrality
Skin-safe sessions require a pH between 5.5 and 7.0. If the gel drifts toward alkaline, the patient gets a chemical sting. Our batches are tested to stay within this window to prevent redness during 30-minute cycles.
Usage Scenarios
Primarily for EMS abdominal belts and wire-free TENS "butterfly" style units. These are the main replacement items for home-use muscle stimulators and wearable pain relief tools.
Supply Chain & Private Label
We manufacture in China and Vietnam to mitigate Section 301 tariffs.
- Customization: We can print your brand on the blue carrier film or the PET liner.
- Packaging: Bulk 10-piece pouches or 2-piece retail sets in foil bags with custom barcodes.
Certifications & QC
- Audits: ISO 13485 and MDSAP.
- Compliance: CE (MDR), FDA 510(k) for the hydrogel component.
- Batch Control: Every production run is tracked. We test peel strength and impedance for every 5,000 units.
Hard Engineering FAQ
Q: Why does the gel lose conductivity before it loses stickiness?
A: Evaporation. The gel is sticky because the polymer is still there, but the ions need water to move. Once the water dries out, the circuit breaks.
Q: Can we change the blue film?
Yes. We can swap the carrier to clear or white, but blue is the industry standard for visibility during application.
Validation Action
If your current gel sheets are delaminating or causing stinging, the polymer balance is wrong.
