: Halloysite is a thin tube material formed by weathering feldspar.

They are generally less than 0.25 µm in diameter and feature tube lengths from 0.5 to 3µm. It is sometimes referred to as Halloysite Nanotube (HNT).

​

High-quality HNTs are relatively rare and are being produced commercially by only a few producers. Among them, ULTRApure HNT, which is refined from high-quality feldspar mined in mines in Idaho, USA, is a high-purity product that is optimal for use in plastic compounding.
