Halloysite Nano Clay

Halloysite Nano Clay (Al₂Si₂O₅(OH)₄•2H₂O+SiO₂) is an aluminosilicate clay-like mineral occurring in soft, smooth, amorphous masses of a whitish color. It is 50% silica and 50% clay. Halloysite forms naturally occurring nanotubes similar to a grain of rice but considerably smaller and hollow. It shows low electrical and thermal conductivity and strong hydrogen interactions. Significant improvements in thermal and mechanical properties have been reported on the addition of halloysite nanotubes in polymer composites.
Typical Applications

Halloysite clay is used to produce china. The clay can be used as a suspension agent in ceramic glaze preparations. It is used as a catalyst in motor vehicle exhaust systems to clean up exhaust gases. Other uses include time-release capsules, dissolving over time to release antifouling paint, antiscalants, herbicides, pest repellants, and other agents that could benefit from a controlled release.
Niche applications include carriers of active ingredients in paints, coatings, and building materials, agricultural applications, and high-performance fillers in plastic composites.
The main target markets for halloysite are: nanocomposites, high-performance polymer reinforcement, controlled release of biological and chemical agents, and advanced ceramics
