PE Foam TENS Electrodes

Closed-cell PE foam electrodes. Engineered with a high-adhesion hydrogel matrix and fluid-resistant backing for high-moisture clinical environments.

These electrodes utilize a closed-cell polyethylene (PE) foam backing instead of standard spunlace non-woven fabric. The hardware is deployed in clinical settings where external moisture, wipe-downs, or high patient perspiration dictate the substrate selection. The core promotional and functional asset of this assembly is the proprietary high-adhesion hydrogel applied beneath the carbon layer, which maintains electrical continuity when the external foam acts as a fluid barrier. We manufacture these standardized blanks for B2B rehabilitation suppliers.

• Closed-Cell Fluid Barrier 

  Standard spunlace fabrics act as wicks. If a patient sweats heavily or the clinician wipes the surrounding tissue with saline, the liquid penetrates the porous fabric and dilutes the active conductive gel. The PE foam substrate acts as a physical shield. This mechanical barrier prevents the underlying hydrogel from prematurely swelling or washing out when exposed to cross-environmental moisture during active therapy. 

   

• High-Adhesion Hydrogel Baseline 

  The primary functional driver of this pad is the high-tack gel layer. PE foam inherently lacks the multi-directional stretch and compliance of non-woven fabric. Mechanical stress from patient movement therefore transfers more directly to the skin-gel interface. The high-adhesion hydrogel formulation establishes a 3.0N physical anchor, countering the relative stiffness of the foam backing and preventing the electrode edges from detaching during joint flexion. 

   

• Clean-Edge Die-Cutting

  Non-woven substrates often leave microscopic fiber lint around the perimeter after high-speed mechanical stamping. The cellular structure of PE foam cuts cleanly under a sharp steel rotary anvil. This process yields a defined, blunt edge that resists fraying. The absence of lint prevents fiber contamination along the adhesive perimeter when the pads are stored and transported across fluctuating temperature zones.

• Dimension Scalability : We support standard 50x50mm and 50x90mm formats. The PE foam backing accepts precise custom steel-rule die-cutting for proprietary geometries. 

• Supply Chain Routing : Raw material lamination and conductive coating run in China. Final die-cutting, terminal crimping, and retail batching are executed at our Vietnam hub to manage supply chain resilience and optimize global freight variables.

• Regulatory: Product files support CE (MDR) and FDA 510(k) registrations under the OEM client's brand. 

• Systems : Assembly lines operate within audited ISO 13485:2016 frameworks, ensuring traceability from raw foam block to sealed pouch.

B2B medical distributors can request physical samples to test the peel force of the hydrogel against the foam backing.
