Description

Octadecanamide, N,n-Dibutyl- is a high-purity, synthetic fatty acid amide derivative, also known by its CAS number 5831-88-9. This compound serves as a versatile intermediate and functional additive, valued for its ability to modify surface properties and enhance material performance. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries for applications requiring internal or external lubrication, slip, and anti-blocking effects.

Application

• As a highly effective internal lubricant and slip agent in polyolefin films (e.g., LDPE, LLDPE, HDPE) to improve processing and surface characteristics.
• Functioning as a key processing aid and mold release agent in engineering plastics and thermoplastic elastomers to reduce friction and prevent sticking.
• Utilized as a viscosity modifier and anti-foaming agent in industrial lubricants and greases.
• Acting as a surface modifier and anti-blocking agent in pigment masterbatches and polymer compounds.
• Serving as an intermediate in the synthesis of more complex surfactants and specialty chemicals for various industrial formulations.
• Potential use as a corrosion inhibitor component in protective coatings and fluids.
