الأسئلة الشائعة
What is kaolin primarily used for?
Kaolin is widely used in ceramics, paper coating, paints, plastics, and as a filler or extender in adhesives, rubber, and pharmaceuticals due to its fine particle size and inert properties.
What is the chemical formula and molecular weight of kaolin?
Kaolin has an approximate formula of **Al₂Si₂O₅(OH)₄**, but its molecular weight (MW) is not defined due to its variable water content and layered structure.
How should kaolin be stored?
Kaolin should be stored in a dry, well-ventilated area at ambient temperature, protected from moisture to prevent clumping or degradation.
What grades of kaolin does Molekula supply?
Molekula supplies **technical-grade kaolin** suitable for industrial applications, including ceramic, paper, and filler uses. Custom grades may be available upon request.
Can Molekula supply kaolin in bulk quantities?
Yes, Molekula can supply kaolin in bulk, with quantities tailored to meet your production needs—contact us for specific packaging options.
What documentation comes with a kaolin order?
Each order includes a **Certificate of Analysis (CoA)**, Material Safety Data Sheet (MSDS), and a packing list detailing product specifications and batch information.
