Discover the Calcium Stearate for PVC Products

Calcium stearate, also known as calcium octadecanoate, is a salt of stearic acid and calcium. It is a white or slightly yellowish powder that is insoluble in water but soluble in organic solvents such as acetone, ether, and chloroform. Calcium stearate is widely used as a lubricant, flow agent, and release agent in various industries.

In the plastics industry, calcium stearate is commonly used as a processing aid to improve the flowability of plastic materials during extrusion, injection molding, and other processing techniques. It reduces friction between the plastic particles and the processing equipment, thereby improving the efficiency of the process and reducing energy consumption.

Additionally, calcium stearate is used as a lubricant in rubber processing to enhance the flow and dispersion of rubber compounds, improve the surface finish of rubber products, and reduce the friction during molding and extrusion.

In the coatings and inks industry, calcium stearate is employed as a rheology modifier to control the viscosity and flow properties of coatings and inks, ensuring smooth application and uniform coverage.Furthermore, calcium stearate finds applications in the lubricants and greases industry, where it serves as an anti-wear agent and extreme-pressure additive, protecting metal surfaces from friction and wear.
