Description

Perfluoro-2,5,8,11,14-Pentamethyl-3,6,9,12,15-Pentaoxaoctadecanoicacid,Methylester97% is a high-purity, fully fluorinated polyether derivative with a methyl ester functional group. This compound is valued for its exceptional chemical inertness, thermal stability, and unique surface-active properties derived from its perfluorinated backbone. It is primarily sought by R&D and industrial chemists in the advanced materials, specialty polymer, and surface coating sectors for creating fluorinated intermediates, high-performance lubricants, and hydrophobic surface modifiers.

Application

• Fluorinated Polymer & Resin Synthesis: Acts as a key monomer or macromonomer for synthesizing high-performance fluoropolymers with enhanced chemical and thermal resistance.
• Specialty Lubricants & Greases: Used as a base fluid or additive in formulations requiring extreme pressure, wide temperature range operation, and compatibility with aggressive chemicals.
• Surface Modification & Coatings: Imparts superior hydrophobicity, oleophobicity, and low surface energy to textiles, electronics, and optical components.
• Advanced Material Research: Serves as a critical building block in R&D for novel fluorinated surfactants, electrolytes, and nanostructured materials.
• Pharmaceutical & AgroChemical Intermediates: Utilized in the synthesis of fluorinated active ingredients or prodrugs where enhanced bioavailability or metabolic stability is desired.
• Electronic Chemicals: Potential application in dielectric fluids, heat transfer media, or cleaning agents for sensitive electronic manufacturing processes.
