Talc Materials Handled Flexicon Corporation

Characteristics and Challenges: Talc is characterized by hydrophobic surface properties, chemical inertness and a slippery feeling. Although all talcs share the same basic properties inertness, softness, water repellency and an affinity for organic substances each talc ore body has its own features, so no two talcs are quite the same. 4
