Stearic Acid, or Octadecanoic Acid, is a fundamental fatty acid with widespread industrial applications. While the chemical composition is largely consistent, the manufacturing process, particularly the degree of pressing, leads to distinct grades that affect performance. For businesses looking to buy Stearic Acid, understanding these differences – Triple Pressed, Double Pressed, and Single Pressed – is crucial for selecting the optimal grade for their specific needs. As a leading manufacturer and supplier from China, we offer a comprehensive range of Stearic Acid grades to meet diverse requirements.

The 'pressing' process refers to the method used to refine Stearic Acid, separating it into different fractions based on melting points and purity. Triple Pressed Stearic Acid is the most refined, typically exhibiting the highest purity (often around 99%) and a higher melting point. It is generally preferred for applications where maximum hardness, whiteness, and stability are required, such as in high-quality candles, certain cosmetic formulations, and pharmaceuticals. Its low iodine value makes it ideal for demanding uses.

Double Pressed Stearic Acid offers a good balance between purity and cost, making it a popular choice for many industrial applications, including some candle making, PVC stabilization, and rubber processing. Single Pressed Stearic Acid, while less refined, is still a valuable product for applications where the highest purity is not critical, such as in some types of lubricants or certain industrial soaps. As a dedicated supplier, we ensure that each grade of Stearic Acid we provide meets stringent quality controls. We encourage you to contact us to discuss your specific application and secure the best grade of Stearic Acid at competitive prices from our China-based facility.
