Description

Triethylene Glycol Bis(2-Ethylhexanoate) is a high-performance, non-phthalate plasticizer and specialty ester. This compound matters for formulators seeking a versatile, low-volatility additive that imparts excellent flexibility and durability to polymeric materials. It is primarily needed by manufacturers in the plastics, coatings, and specialty chemical industries for creating flexible PVC, synthetic rubbers, and high-performance lubricants. Its compatibility and stability make it a key ingredient in demanding applications.

Application

• Primary plasticizer for flexible PVC products such as cables, hoses, and films.
• Co-plasticizer and viscosity modifier in synthetic rubber and elastomer formulations.
• Functional fluid and base component in high-temperature synthetic lubricants and greases.
• Plasticizer for adhesives, sealants, and caulks requiring low migration and volatility.
• Additive in paints and coatings to improve film flexibility and pigment dispersion.
• Processing aid and internal lubricant in various engineering plastics.
• Component in specialty metalworking fluids and rolling oils.
