Description

Fatty Acids, C5-9, Tetraesters With Pentaerythritol is a synthetic ester-based chemical compound, specifically a tetraester of pentaerythritol with C5-C9 fatty acids. This product serves as a versatile intermediate and functional additive, valued for its lubricity, plasticizing properties, and hydrophobic character. It is primarily utilized by formulators and manufacturers in the lubricants, plastics, coatings, and personal care industries seeking specialized ester performance.

Application

• Lubricant & Grease Formulation: Acts as a synthetic base oil or additive to enhance lubricity, reduce friction, and improve low-temperature performance in industrial and automotive lubricants.
• Polymer & Plastic Modification: Functions as an internal or external lubricant and plasticizer in PVC and other polymer processing to improve flow and reduce melt viscosity.
• Coating & Ink Additive: Used to modify rheology, improve pigment wetting, and enhance surface slip and water resistance in various coating systems.
• Personal Care & Cosmetics: Employed as an emollient and skin-conditioning agent in cosmetic formulations, providing a non-greasy feel.
• Metalworking Fluids: Serves as a lubricity component and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids.
• Specialty Chemical Intermediate: Used in the synthesis of more complex esters, surfactants, and other functional chemicals.

Quality Control

Our Fatty Acids, C5-9, Tetraesters With Pentaerythritol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as ester content, acid value, hydroxyl value, and viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong alkalis and incompatible materials such as strong oxidizing agents. For long-term storage, consider using an inert gas blanket to minimize oxidation.
