Description

n-Butyl Stearate is a clear, oily liquid ester derived from stearic acid and n-butanol, known for its excellent lubricating properties and low volatility. This versatile chemical intermediate is valued for its ability to act as a plasticizer, lubricant, and emollient across diverse manufacturing processes. It is essential for formulators and manufacturers in the plastics, personal care, and textile industries seeking to improve product performance and processing characteristics.

Application

• Plasticizer & Lubricant for Polymers: Used in PVC, polystyrene, and other resins to improve flexibility, reduce melt viscosity, and aid in processing.
• Personal Care & Cosmetics: Functions as a non-greasy emollient and skin-conditioning agent in creams, lotions, and makeup formulations.
• Textile & Fiber Processing: Acts as a softening agent and lubricant for synthetic fibers and yarns to reduce friction during spinning and weaving.
• Metalworking & Industrial Lubricants: Serves as a component in cutting oils, drawing compounds, and release agents due to its good lubricity and stability.
• Rubber Industry: Employed as a processing aid and mold release agent to facilitate the manufacturing of rubber products.
• Inks & Coatings: Used as a flow modifier and lubricant to enhance the application properties and surface finish of various coatings.
