Silica Gel 100% Blue 15kg

Premium Blue Indicating Silica Gel Desiccant (2 - 4mm Spherical Beads)

Silica Gel Direct's 100% blue bulk silica gel is a highly activated adsorbent engineered for demanding industrial, commercial, and technical applications. Featuring a strong natural affinity for moisture and high crush strength, this blue beaded desiccant provides reliable humidity control and dynamic gas/liquid drying. Impregnated with a cobalt chloride color indicator, the beads change dynamically from blue to pink as they become saturated, making monitoring effortless.

Key Benefits & Features

• Clear Saturation Indicator: Changes cleanly from blue to pink, giving you an immediate visual cue when the desiccant has reached capacity and needs replacement or reactivation.

• High-Capacity Moisture Adsorption: Has a high moisture capacity below 25°C at relative humidities above 40%, absorbing up to ≥28% of its weight in high-humidity environments.

• Non-Corrosive & Chemically Stable: Non-corrosive and chemically stable under standard operating conditions. Remains completely dry to the touch even when fully saturated, leaving no liquid residues or corrosive by-products.

• Versatile Chemical Adsorbent: In addition to water, silica gel effectively adsorbs HCl, gasoline-range hydrocarbons, CO₂, Cl₂, sulfur and nitrogen compounds, aromatics, and other organic vapors.

• High Crush Strength & Uniformity: Durable 2–4mm spherical beads (≥90% within size range) resist dusting and breaking down, maintaining optimal airflow in high-pressure systems.

• Heavy-Duty Packaging: Packed in a 15kg HDPE Bucket to ensure maximum product freshness during transit and storage.
