Premium Rubber Grade Stearic Acid for Industrial Manufacturing

Technical Overview of Rubber Grade Stearic Acid

Our rubber grade stearic acid (commonly known as Stearic Acid 1801) is a high-quality saturated fatty acid widely used as a vital vulcanization activator in the rubber industry. It features excellent heat stability and low volatility, ensuring optimal performance during the rubber compounding process.

Key Functions in Rubber Manufacturing

• Vulcanization Activator: Acts as a co-activator with zinc oxide to speed up the vulcanization rate and improve cross-linking efficiency.

• Internal Lubricant: Enhances the flowability of rubber compounds, reducing energy consumption during mixing and extrusion.

• External Mold Release Agent: Provides a smooth surface finish and prevents the rubber from sticking to the molds.

Common Applications

• Rubber compounding and tire manufacturing

• PVC stabilization and plastic processing

• Cosmetics and personal care products

• Pharmaceuticals and food additives

• Soaps and cleaning agent formulations
