Talc (magnesium silicate, chemical formula Mg3(OH)2/Si4O10)
- Lamellar nature: talc can be classified as either microcrystalline (length:thickness = 10:1) or macrocrystalline (length:thickness = 35:1)
- Low Mohs hardness of 1 (being the softest mineral in the range)
- Hydrophobic surface and, as a result, low water absorption
- High brightness
- High purity
- High inertness in various media.
By using the appropriate micronisation technology, the Tital VT grades are processed to various particle size distribution, maintaining the product’s characteristic lamellarity and high aspect ratio.
Due to its lamellar structure and hydrophobic nature, talc will provide barrier properties and good chemical resistance compared to conventional fillers.
Mechanical reinforcement: due to its lamellar structure, talc will mechanically reinforce the binder matrix.
