Based on available research on earthing materials and grounding applications, here's a comparison of Bentonite vs Chemical Conductive Gels for earthing/grounding systems: Performance Comparison Table Parameter Bentonite Clay Chemical Conductive Gel Electrical Resistivity 2–5 Ω·m (when hydrated) 0.1–0.5 Ω·m Moisture Retention Excellent (swells 3–4× when wet) Superior (hydrophilic polymers) Conductivity Mechanism Water-dependent; needs moisture to maintain conductivity Ionic conductivity from salts/minerals; works even in dry conditions Lifetime 5–10 years (dries out over time) 10–15+ years (no water needed) Temperature Stability Good (−10°C to 50°C); loses conductivity when frozen/dried Better (−40°C to 80°C); freezing-tolerant, retains conductivity Corrosion Impact Low (natural clay, pH-neutral) Varies (some acidic gels corrode GI rods; use non-acidic formulas) Installation Mix with water; requires water source Ready-to-use ...
