Industrial-grade TOPY MICA is broadly divided into two types: "swellable type" and "non-swellable type." Swelling is the property of a substance to increase in volume by absorbing water or a solvent.
The "swelling type," as shown in the diagram on the right, incorporates water molecules between layers, ultimately causing the material to delaminate down to almost a single layer.
Swelling type
Because the primary particles are large and have a high aspect ratio, they exhibit high gas barrier properties.
Non-swelling type
Its distinguishing feature is its higher heat resistance compared to natural mica.
Examples of applications: lubricants, resin additives, etc.
Please refer to the table below for the basic physical properties of synthetic mica.
