Frequently Asked Questions

Q: What is the difference between washed and calcined kaolin clay?

Washed kaolin is purified by removing impurities through water, while calcined kaolin is heated at high temperatures to remove chemically bound water, resulting in higher whiteness and heat resistance.

Q: How does calcined kaolin clay 325 mesh benefit the paint industry?

It acts as a filler and extender that improves opacity, increases viscosity, and prevents paint from sagging, ensuring a smooth and durable uniform finish.

Q: Why is Kaolin clay essential for high-quality ceramic production?

Due to its high plasticity and ability to withstand extreme heat, it improves the strength, finish, and durability of porcelain and sanitaryware.

Q: What factors typically influence the wholesale price of Kaolin clay?

Pricing is influenced by the purity of the source material, the processing method (e.g., calcination), particle size (mesh), and the total volume of the order.

Q: Is your Kaolin clay suitable for use in cosmetics?

Yes, kaolin is a natural mineral used in cosmetics for its high oil and water absorption and its ability to adjust brightness for a natural color sense.

Q: Which mesh sizes are available for industrial bulk orders?

We provide a wide range of specifications including 200, 325, 400, 600, 800, 1250, 2000, and up to 6000 mesh to meet specific industrial needs.
