Frequently Asked Questions

What is silica gel used for?

Silica gel is primarily used as a desiccant to control humidity in packaging, electronics, pharmaceuticals, and industrial processes. It absorbs moisture and prevents spoilage, corrosion, and mold.

Is silica gel safe for pets?

Yes, silica gel used in cat litter is non-toxic and safe for pets when used as directed. However, ingestion of large quantities should be avoided.

Can silica gel be reused?

Yes, silica gel can be regenerated by heating at 120–150°C for several hours, restoring its moisture-absorbing capacity.

What’s the difference between indicating and non-indicating silica gel?

Indicating silica gel changes color when saturated with moisture (e.g., orange to green), while non-indicating remains the same color and requires testing to determine saturation.

Do you offer custom packaging and private labeling?

Yes, we provide OEM services including custom packaging, labeling, and formulation adjustments based on client requirements.
