Description

Fatty Acids, (C=16~18) And (C=18)-Unsatd., Branched And Linear, Bu Esters is a specialized blend of butyl esters derived from a mixture of C16-C18 saturated and unsaturated fatty acids, including both branched and linear isomers. This unique composition provides a versatile chemical intermediate with excellent solvency, lubricity, and formulation flexibility for demanding industrial applications. It is particularly valuable for manufacturers in the lubricant, polymer, and specialty chemical sectors seeking consistent performance and reliable supply.

Application

• Lubricant & Metalworking Fluid Additive: Acts as a friction modifier, emulsifier, and corrosion inhibitor in synthetic and semi-synthetic lubricants and cutting fluids.
• Polymer Plasticizer & Modifier: Used to improve flexibility, processability, and low-temperature performance in PVC, rubber, and other polymer systems.
• Solvent & Carrier Fluid: Serves as a high-boiling, low-volatility solvent for agrochemicals, coatings, and ink formulations.
• Surfactant & Emulsifier Intermediate: A key raw material for the synthesis of specialty surfactants, emulsifiers, and dispersants.
• Personal Care & Cosmetic Ingredients: Used in the production of emollients and conditioning agents for skin and hair care products.
• Fuel & Oil Additive: Functions as a detergent and dispersant additive in fuel and lubricant packages to prevent deposit formation.
