Description

Potassium Perfluoropentanoate is a high-purity, fully fluorinated carboxylic acid salt, also known as potassium perfluorovalerate. This specialty fluorochemical is valued for its exceptional surface activity, thermal stability, and chemical inertness, making it a critical performance additive in advanced industrial formulations. It is primarily utilized by manufacturers in the fluoropolymer, electronics, and specialty surfactant industries seeking to enhance product performance and process efficiency.

Application

• As a surfactant and emulsifier in the emulsion polymerization of fluoropolymers like PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene).
• As a foam stabilizer and wetting agent in fire-fighting foams (AFFF) and specialty cleaning formulations.
• As a surface treatment agent for textiles, leather, and paper to impart oil, water, and stain resistance.
• As a processing aid and dispersant in the production of coatings, inks, and electronic materials.
• As a key intermediate in the synthesis of more complex fluorinated surfactants and pharmaceuticals.
• In analytical chemistry and research as a standard or reagent due to its defined fluorinated structure.

Quality Control

Our Potassium Perfluoropentanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, impurity profile, and moisture content. Our quality commitment ensures the material meets the stringent requirements for use in high-performance industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
