Calcium stearate, the calcium salt of stearic acid, is a fine, hydrophobic powder universally preferred across multiple industries, as it is a versatile compound with broad industrial relevance. Calcium Stearate functions as a mold release agent by improving material flow and preventing sticking during molding, and also serves as an internal/external lubricant, thickener, matting aid, and lubrication additive in plastics, rubber, and coatings. In pharmaceuticals, specific grades act as excipient lubricants in tablet formulations, while in rubber processing, it enhances handling and surface finish. In coatings, its octadecanoic acid component contributes to thickening, matting, and water repellency. Aqueous dispersion form (50% active) is specifically designed for water-based paints, paper coatings, and textile finishes, offering the same performance in a more convenient liquid format. Commonly referred to as (calcium distearate, Calstar, or Flexichem) by by “Calcium Stearate” supplier and manufacturer. We are a leading and trusted global supplier of calcium stearate, including in the United States, known for our reliable lead times and strong supply capabilities.

Lubricant and mold release to prevent sticking; improves part ejection and surface finish
Matting/thickening aid; improves slip and water repellency
Tablet lubricant/excipient for improved die release (grade-dependent)
Enhances processability, reduces die build-up, supports hydrophobicity, and stabilises appearance
Aqueous emulsion (~50% active), stabilized with surfactants, designed for water-based coatings and paper systems
Pharma (USP/Ph. Eur.), food-grade (where regulatory approvals exist).
15–30 °C
Cool, dry; protect from moisture; keep sealed to maintain flowability
25 kg bags, fiber drums; bulk on request
24 months under recommended storage.
No; it’s water-insoluble and hydrophobic; disperses in non-polar media.
Powder is the standard form, while dispersion is an aqueous emulsion (~50% active) designed for easy use in water-based systems like paints, paper, and textiles.
Using a dispersion offers several practical advantages, especially in water-based manufacturing processes like paint formulation and paper making.
Acts as an internal/external lubricant and mold release, reducing friction and sticking
Often 0.3–2% w/w depending on polymer and tooling.
Standard and micronized grades (e.g., D50 ~6–10 µm), to be specific 10.0-12.0 & 4.0-6.0 for LDF, LF respectively
Yes, along with documents-COA, TDS, SDS; regulatory declarations on request.
Standard 20–25 kg; stock or 2–3 weeks for bulk/custom.
Yes, if supplier deals, pharmacopeia grades are used as tablet lubricants and excipients.
