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.

Where is Dipentaerythrityl hexa C5-9 acid esters used?

• Lubricants: synthetic base oil for high-temperature greases, compressor oils and aviation-adjacent fluids where polyol esters outperform mineral oil in oxidative stability
• Metalworking fluids: improves film strength and reduces tool wear in cutting and forming operations
• PVC and specialty polymer compounds: plasticizer with low migration and improved heat resistance
• Coatings and sealants: adjusts flexibility and extends service life in high-temperature or UV-exposed end products
• It functions as a base fluid and plasticizer in demanding industrial formulations.

Good to know: Thermal stability and low volatility are critical sourcing criteria. It offers performance advantages compared to conventional phthalate-based alternatives.

Commercial specifications

• Purity and ester value specifications typically confirmed by certificate of analysis
• Bulk liquid supply in IBC and drum formats
