Orange Silica Gel

Orange Silica Gel

Silica Gel Desiccant
This substance has silicon dioxide as its primary component, and its color changes in response to humidity. In addition to the performance characteristics of blue silica gel, it also features being cobalt - chloride - free, non - toxic, odorless, and harmless.
Its molecular formula is \(SiO_{2}+H_{2}O + C_{25}H_{30}ClN_{3}\). Please note that the symbol for chlorine in the formula should be “Cl” rather than “CL” for correct chemical notation.

Product Description

Eco-Friendly Indicating Desiccant

Orange Silica Gel (Color-Changing Moisture Indicator)

An advanced, heavy-metal-free indicating desiccant engineered with a distinct visual color transition to track moisture saturation safely and efficiently in critical packaging and industrial equipment.

Color Transition
Orange to Green / Yellow
Safety Profile
Cobalt-Free / Non-Toxic
Adsorption Capacity
≥ 30% (at RH=80%)
Attrition Loss
≤ 0.3 wt% (High Durability)

Visual Saturation Tracking Without Toxic Risks

Traditional indicating desiccants relied on cobalt chloride, which is classified as toxic. Orange silica gel utilizes an environmentally safe organic indicator that shifts reliably from vibrant orange to green or light yellow as moisture is absorbed.

Its high-purity amorphous structure provides millions of interconnected pores that trap water vapor rapidly while offering a clear, unmistakable visual cue when regeneration or replacement is required.
