Frequently Asked Questions

What is vermiculite used for?

Vermiculite is used in horticulture as a soil conditioner, in construction for insulation and fireproofing, and in industrial applications as an absorbent and packaging void filler.

What's the difference between vermiculite and perlite?

Vermiculite retains water and nutrients, making it ideal for moisture retention. Perlite improves aeration and drainage but holds less water. Both are used in soil mixes.

Is quartz sand suitable for water filtration?

Yes, high-purity quartz sand is widely used in water filtration systems due to its hardness, chemical stability, and uniform particle size.

Do you offer custom packaging?

Yes, we provide flexible packaging options including 20kg, 25kg PP bags, jumbo bags, and customized solutions based on client requirements.

Yes, we offer sample shipments to evaluate product quality. Contact us to request samples of any mineral product.
