Clay Desiccant · Natural Montmorillonite & Bentonite 5g–1kg

Clay desiccant (activated clay) is derived from natural Montmorillonite or Bentonite minerals through mining, purification and granulation to a standard 2–4mm bead size. It is a fully inorganic, non-toxic material that poses no environmental hazard during disposal. Clay absorbs up to 40% of its own weight under normal conditions. Its key technical advantage over Silica Gel is thermal stability: Clay maintains consistent performance across a low-temperature range (5–25°C) without bead fracturing or swelling when subjected to sudden temperature changes · a critical property in refrigerated containers or winter shipping routes. The tradeoff is that Clay cannot be regenerated by heat and must be replaced after each use cycle.
