Key features

99% High Purity # Water process ensures > and = 99% purity, far exceeding dry process grades (95 to 97%)

D50: 2 to 8 micron Ultra-Fine Particles # Water process delivers D50 particle size of 2 to 8 micron with narrow distribution, eliminating coarse agglomerates

greater than or equal to280 degree Thermal Stability # Thermal decomposition temperature greater than or equal to280 degree; no discoloration during high temperature PVC extrusion

less than or equal to0.5% Low Moisture Content # Advanced drying process keeps moisture less than or equal to0.5%, preventing caking during storage

Balanced Internal/External Lubrication # Higher specific surface area provides superior internal/external lubrication balance in PVC compounds

0.5 to 2.0phr Low Dosage # Effective at just 0.5to 2.0phr, reducing additive cost without compromising performance

Minimal Haze in Transparent PVC # Fine particles minimize transparency loss ; ideal for light-colored and semi-transparent applications

Dust-Free Flowing Granules # Spray-granulated product flows freely; cleaner, safer factory environment vs. powdered grades

No Solvent Used in Production # 100% water-based production process; eco-friendly and compliant with REACH/RoHS

12-Month Shelf Life # Properly packaged, stable for over 12 months in sealed storage conditions

Product Q&A

Q:Are you a trading company or manufactuer?

We are a manufactuer with over 20 years of experience.

Q:What is water process calcium stearate and how is it different?

Water Process Calcium Stearate is manufactured via direct aqueous neutralization of high-purity stearic acid with calcium hydroxide , a wet chemical process. Unlike dry process grades (which mechanically mix stearic acid with calcium oxide), water process achieves molecular-level reaction, producing higher purity (over 98.5%), finer particle size (D50 2 to 8 micron), and better dispersibility in PVC and plastic compounds. It functions as both an internal and external lubricant

Q:What are the key specifications of your calcium stearate?

Our standard product specifications: Purity over 98.5%; Moisture less than 0.5%; D50 Particle Size 2to 8 micron ; Bulk Density 0.3to0.5 g/cubic cm; Melting Point 147 to 149 degree; Thermal Decomposition over 280 degree ; pH (10% suspension) 7 to 9. Customized specifications (particle size, bulk density, granular/powder form) are available upon request. Full COA provided per batch.

Q:Which industries and applications use calcium stearate?

Widely used across multiple industries: (1) PVC Lubricant : rigid PVC pipes, profiles, fittings, window/door frames (dosage 0.5 to 2.0 phr); (2) Rubber Processing : release agent and flow improver, prevents mold sticking; (3) Plastics : anti-blocking agent and acid scavenger in PE, PP; (4) Construction :mold release for concrete, gypsum, waterproofing additive;

Q:What is the packaging and shipping method?

Standard packaging: 20 kg net weight in kraft paper bags with PE inner liner (also available in 25 kg bags). Palletized packing: 40 bags per pallet (800 kg), stretch wrapped. 20 ft FCL loads approximately 16 MT (palletized). Shipping terms: FOB Shanghai . Lead time: 7 to 15 days after order confirmation.
