Calcium Stearate Regular, Powder
Calcium Stearate Regular, Powder is manufactured using the fusion process. The regular grade of Calcium stearate is often used for general purposes and ceramics.
Calcium stearate is a carboxylate which is formed from stearic acid and calcium oxide. Its primary uses are as a flow agent, stabilizer, thickener, and surface conditioner. Calcium Stearate Regular, Powder acts as a catalyst neutralizer and lubricant in various polymer resins, such as polypropylene (PP). This particular grade of calcium stearate is in powder form and offers multiple performance benefits depending on your application.
Specifications
Color: White Form: Powder CAS number: 1592-23-0 Water S-soluble salts %: 0.00–0.29 Molecular formula: C36H70CaO4 Fineness, % thru 40 mesh: 100.00 (min) Fineness, % thru 325 mesh: 99.00–100.00 Water %: 0.00–3.00 Melting point: 160 °C Insoluble in H2O Free fatty acids (as stearic): 0.50 (max)
Primary Chemistry: Calcium stearate
Features & Benefits
Great in uses such as thin fibers and films as a waterproofing agent Release agent, lubricant, and anti-tack for plastics In plastics, it may act as an acid scavenger or neutralizer Does not melt but will reach the plastic phase at a normal processing temperature Great catalyst/neutralizer Efflorescence control of cement, concrete and masonry for hydrophobic benefits
Problems Solved
High cost of refined calcium stearates for use in ceramics and industrial applications Coarse or large particle size of calcium stearates for use in plastics and thin-film applications Difficulties in modifying the melt temperature in high-temperature applications
Applications
Adhesives Coatings Compounders and masterbatches Packaging (plastic, paper, paperboard) Rigid PVC Ceramics Concrete Lubricants, greases, and oils Fabrics Pencils and crayons
PMC Metallic stearates are oleochemical metal salt compounds of long-chain fatty acids that are used to benefit various plastic manufacturing and applications.
