3.Core Applications
Zinc stearate delivers reliable performance across multiple industries:
Plastics Industry
Stabilizer & lubricant for PVC (non-toxic formulations); enhances photothermal stability when paired with calcium/barium stearate (dosage: <1 part in PVC processing).
Polymerization additive for PP, PE, PS, EPS; dispersant & thermal stabilizer for high-end color masterbatches.
Rubber Industry
Softening lubricant & mold release agent; improves processability (dosage: 1–3 parts).
Coatings & Textiles
Paint drier (accelerates curing); glazing agent for textiles (boosts surface smoothness).
Other Uses
Pharmaceutical formulation (lubricant for tablet manufacturing); pencil lead production; hydrogenated oil additives.
