Triple Pressed / Rubber Grade
Stearic Acid is a long-chain saturated fatty acid derived from renewable vegetable fats (Palm Oil). Ruvon offers premium Triple Pressed and Rubber Grades, characterized by excellent thermal stability, lubricating properties, and high purity. It is a critical activator in rubber vulcanization and a key texturizer in cosmetics.
Stearic Acid is a solid, white crystalline fatty acid. Commercially, it is a blend of Stearic Acid (C18) and Palmitic Acid (C16). The ratio of C18 to C16 determines the grade (Triple Pressed vs. Rubber Grade) and its melting point properties.
We supply grades tailored for Rubber Activation and High-End Cosmetic Emulsification.
