Factory Direct Supply Industrial Calcium Stearate Powder With High Purity and Stable Quality

Calcium Stearate is an organic compound, the molecular formula is C36H70CaO4, white powder, insoluble in water, can be used as water repellent agent, lubricant and plastic additives.

Key Benefits:

Improves processing efficiency as a lubricant in plastics (e.g., EPS, PE, PP, PS, PVC, SMC, BMC, masterbatch).

Supports clean demoulding and helps reduce sticking in rubber processing.

Acts as a release agent in amino plastic applications.

Water-insoluble / hydrophobic behavior (insoluble in water), suitable for formulations requiring water-repellent performance.

Good dispersion potential with fine particle size (200 mesh, 99% passed).
