Description

3-(Octatriacontenyl)Succinic Anhydride is a high-purity, long-chain alkenyl succinic anhydride (ASA) derivative, a critical intermediate in advanced polymer and surface modification chemistry. Its unique structure, featuring a C38 alkenyl chain, provides exceptional hydrophobicity and compatibility for creating tailored performance materials. This specialty chemical is essential for R&D and production teams in sectors demanding precise molecular architecture, such as polymer additives, corrosion inhibitors, and specialty surfactants.

Application

• Polymer Additives & Modifiers: Acts as a key monomer or cross-linking agent for synthesizing high-performance polymers, resins, and epoxy curing agents, enhancing flexibility and hydrophobic properties.
• Corrosion Inhibitors: Used in formulating high-efficiency oilfield and industrial corrosion inhibitors, where its long hydrophobic chain provides excellent film-forming and metal-surface adhesion.
• Surface Modification & Coupling Agents: Employed to modify the surface properties of inorganic fillers (e.g., silica, calcium carbonate) to improve dispersion and compatibility in polymer matrices.
• Specialty Surfactants & Emulsifiers: Serves as a precursor for synthesizing novel surfactants with specific hydrophilic-lipophilic balance (HLB) for demanding emulsion formulations.
• Lubricant & Fuel Additives: Utilized in the development of ashless dispersants and anti-wear additives for advanced lubricants and fuel systems.
• Paper Sizing Agents: Functions as a reactive sizing agent in paper manufacturing to impart water resistance.
• Adhesive & Sealant Formulations: Incorporated to modify the properties of adhesives and sealants, improving adhesion to low-energy surfaces and moisture resistance.
• Research & Development: A valuable building block in organic synthesis and material science research for creating novel functional molecules and materials.
