Description

Dicapryl Adipate (CAS 105-97-5 ), also known as didecyl adipate, is a diester plasticizer and lubricant derived from adipic acid and decyl alcohol. It functions as a low-temperature plasticizer and internal lubricant across polymer processing and industrial lubrication applications. In plastics compounding, it improves flexibility and cold-temperature performance in PVC formulations where standard phthalate or general-purpose adipates fall short. Metalworking and industrial lubricant formulators use it as a base fluid or additive. This chemical helps to reduce friction in cutting oils, rolling lubricants, and gear fluids. In textile processing, it acts as a fiber lubricant and softening agent, improving handle and reducing mechanical stress during yarn and fabric production. Leather finishing formulations incorporate it as a softener to enhance suppleness and durability in treated hides. This versatile ester provides consistent performance across a wide range of thermal conditions and mechanical environments. Dicapryl Adipate is supplied as a clear, low-viscosity liquid in drum and IBC quantities suited to industrial-scale procurement. Technical grade is the standard commercial offering, with purity specifications typically at 99% or above. Buyers sourcing for sensitive applications should confirm ester content and acid value with the supplier's certificate of analysis. This ensures the material meets the specific requirements for high-performance industrial and chemical manufacturing. Contact us for supply of Dicapryl Adipate Request Quote
