Nano clays are used in a wide range of applications across various industries. In the polymer nanocomposites industry, they are added to polymers to improve mechanical strength, thermal stability, and barrier properties. In the cosmetics industry, nano clays are used in formulations to enhance texture and stability. They are also used in drug delivery systems, water purification, and as additives in coatings and paints to improve properties such as scratch resistance and UV protection.
