Electronics Silica Gel Desiccant Manufacturers

This electronics silica gel desiccant is a highly efficient moisture absorbing material. It is specially designed for electronic products, precision instruments and sensitive equipment, etc. This desiccant has extremely strong moisture absorption capacity and stability. It can effectively control the humidity of the environment, prevent moisture, mold and oxidation from damaging electronic components, and extend the service life of the product.

Noted: We can custom for specific applications.

Parameter	Specification
Product Name	Electronics Silica Gel Desiccant
Material	Silicon dioxide (SiO₂), synthetic amorphous silica gel.
Adsorption Capacity	High adsorption rate ( 35-40% of its weight)
Particle Size	1–5mm (customizable upon request)
Appearance	Transparent or semi-transparent granular material.
pH Range	Neutral (pH 4–8)
Moisture Content	≤ 2% before usage
Regeneration	Reusable after heating (100–120°C for 2–3 hours to remove absorbed moisture)
Packaging	Available in breathable sachets (1g, 5g, 10g, etc.) or bulk packaging.We can custom per your requirement.
Application	Prevent moisture damage to electronics, electrical equipment, and optical devices,etc.
Storage Conditions	Store in a dry, cool, and sealed environment to preserve desiccant effectiveness.

Moisture Absorption Rate (at 25°C)

Relative Humidity (RH)	Absorption Rate (Weight %)
20% RH	≈6%
40% RH	≈12%
60% RH	≈20%
80% RH	≈28%
90% RH	≥30%

Notes

In high-temperature, high-humidity environments (e.g., 30°C, 80% RH), absorption capacity may increase further.
When saturated, the electronics silica gel desiccant changes color, indicating the need for replacement or reactivation.

Recommended Dosage

Type of Packaging Container	Container Volume (Liters)	Recommended Dosage (Grams)	Applicable Scenarios
Small Electronic Component Bag	0.1 - 0.5	5 - 10	Chips, sensors, microcircuits, etc.
Anti Static Bag (20 x 30cm)	2 - 5	20 - 50	PCB board, electronic module, etc.
Medium Sized Sealed Box (Plastic/Metal)	10 - 20	100 - 200	Bulk storage of electronic components, etc.
Large Transport Box (Wooden/Cardboard Box)	50 - 100	500 - 1000	Transportation of complete equipment, precision instruments, etc.
Complete Packaging of Electronic Devices	30 - 50	300 - 500	Servers, medical equipment, etc.

1. Humidity Requirements

If it is necessary to maintain humidity <30% RH (such as military grade electronics), the dosage needs to be increased by 30% -50%.
For ordinary commercial electronics (40% -50% RH) , it can be used according to the reference quantity in the table.

2. Adjustment of Environmental Factors

High Temperature and High Humidity Environment (such as tropical areas): increase the dosage by 20%-30%.
For Sea Transportation or Long-Term Storage: it is recommended to use a combination of calcium chloride desiccant + electronics silica gel desiccant.

3. Replacement Cycle

Unopened Packaging: Valid for 6-12 months (depending on the seal).
Frequent Access After Opening: Check and replace every 3 months.
