Talc

Introduction

Talc (magnesium silicate, chemical formula Mg₃(OH)₂/Si₄O₁₀)

Characterised by:

• 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.

Basic properties

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.
