Stearic Acid
Stearic Acid
Stearic Acid is a saturated fatty acid derived from animal fats and vegetable oils. It appears as white, glossy crystals with a characteristic fatty odor. It is widely used in industries such as rubber, plastics, and cosmetics, thanks to its roles as a lubricant, dispersing agent, and reaction activator.
Chemical Properties:
- Insoluble in water
- Soluble in alcohol and ether
- Highly safe, as it is derived from natural raw materials
Role in the Rubber Industry:
- Acts as a dispersing agent for additives such as carbon black, accelerators, and pigments
- Improves the efficiency of rubber compound mixing
- Functions as a lubricant and activator when used with zinc oxide in the vulcanization process
- Promotes better flow during molding, resulting in smoother surface finishes
Product Information:
- Stearic Acid 1860 – Beads form, imported from Indonesia
- Odorless and non-rancid, suitable for rubber applications
- Comparable in quality to the widely used Stearic Acid 1810
Industrial Applications:
- Rubber industry : For compounding and vulcanization support
- Plastic industry – As an internal lubricant
- Cosmetics and pharmaceuticals – Used in lotions, creams, soaps, and tablet formulations
