Frequently Asked Questions

What is sodium metasilicate pentahydrate used for?▼

Sodium metasilicate pentahydrate is used in detergents, industrial cleaning, construction materials, metal treatment, and textile processing as an alkaline builder and water softener.

What is the difference between sodium metasilicate pentahydrate and anhydrous sodium metasilicate?▼

Anhydrous sodium metasilicate contains no crystal water and provides higher active content for concentrated formulations. Pentahydrate contains crystal water and is widely used in conventional detergent and industrial applications.

Is sodium metasilicate environmentally friendly?▼

Yes. Sodium metasilicate is phosphate-free and biodegradable, making it an environmentally friendly alternative to phosphate-based builders in detergent formulations.

How to choose a reliable sodium metasilicate manufacturer in China?▼

Look for manufacturers with stable production capacity, batch-to-batch consistency, industry standard participation, ISO certification, and proven export experience. Zhongzhi Chemical meets all these criteria.
