Dipentaerythrityl hexa C5-9 acid esters

Dipentaerythrityl hexa C5-9 acid esters (CAS 67762-52-1) is a synthetic polyol ester built from dipentaerythritol fully esterified with branched C5–C9 fatty acids. It functions as a high-performance base fluid and plasticizer across demanding industrial formulations.

In lubricant formulations, it serves as a synthetic base oil for high-temperature greases, compressor oils, and aviation-adjacent fluids where polyol esters outperform mineral oil in oxidative stability. Thermal stability and low volatility are critical sourcing criteria.

Metalworking fluid formulators incorporate it to improve film strength and reduce tool wear in cutting and forming operations. As a plasticizer in PVC and specialty polymer compounds, it delivers low migration and improved heat resistance.

It offers significant performance advantages compared to conventional phthalate-based alternatives. Coatings and sealant manufacturers use it to adjust flexibility and extend service life in high-temperature or UV-exposed end products.

This product is supplied as a clear to pale yellow liquid. Technical grade is the standard commercial offering, with purity and ester value specifications typically confirmed by certificate of analysis for quality assurance.

Bulk liquid supply in IBC and drum formats is standard for industrial procurement volumes. The material is handled according to standard industrial safety protocols to ensure consistent performance in diverse chemical manufacturing environments.
