Description

Hydroxystearic Acid Amide is a high-purity, non-ionic surfactant and slip agent derived from stearic acid. This compound is valued for its excellent lubricating properties and compatibility with a wide range of polymer matrices. It serves as a critical performance additive for manufacturers in the plastics, coatings, and personal care industries seeking to enhance product surface quality and processing efficiency.

Application

• Polymer Processing Aid & Slip Agent: Widely used in polyolefin films (LDPE, LLDPE, PP) to reduce surface friction, improve anti-blocking properties, and enhance gloss.
• Internal and External Lubricant: Acts as an effective lubricant in PVC, engineering plastics, and masterbatches to facilitate smoother processing, reduce torque, and prevent sticking to metal surfaces.
• Surface Modifier for Pigments & Fillers: Improves the dispersion of inorganic fillers (e.g., calcium carbonate, talc) in polymer compounds, leading to better mechanical properties and surface finish.
• Anti-fogging Agent: Employed in agricultural and packaging films to prevent water droplet formation, maintaining clarity.
• Textile and Fiber Auxiliary: Functions as a softening agent and spin finish component to reduce fiber-to-fiber and fiber-to-metal friction.
• Cosmetic and Personal Care Ingredient: Used as an opacifier, viscosity modifier, and emulsion stabilizer in creams and lotions.
• Release Agent: Provides excellent mold release properties in rubber and polyurethane processing.
• Corrosion Inhibitor Component: Finds application in formulating protective coatings and lubricating greases.
