Talc (Paper Grade — Pitch Control & Filler)
CAS Number: 14807-96-6
Talc is a naturally occurring magnesium silicate mineral used in papermaking as a pitch control agent and functional filler. Its hydrophobic platelet structure adsorbs sticky resin and pitch particles from wood pulp, preventing deposition on paper machine components. As a filler, talc contributes to paper opacity, smoothness, and reduced linting during printing.
