ChemFlexx DOP is The Chemical Company’s trade name for di-2-ethylhexyl phthalate, commonly referred to as DEHP or DOP.
TCC’s ChemFlexx DOP, di-2-ethylhexyl phthalate (DEHP, a.k.a. DOP), is the commercial name for the organic compound di(2-ethylhexyl) phthalate, one of the most widely available general-purpose plasticizers in the market. This colorless, viscous liquid is soluble in oil but not in water and is compatible with monomeric plasticizers used in PVC compounding.
Due to its performance profile and broad availability, DEHP is widely used as a plasticizer in the manufacturing of PVC articles. It is also used as a hydraulic fluid and as a dielectric fluid in capacitors, as well as a solvent in specialty applications.
DEHP is the phthalate ester of the alcohol 2-ethylhexanol, which is manufactured through the dimerization of n-butyraldehyde. DEHP is produced by the esterification of phthalic anhydride with 2-ethylhexanol in a two-step reaction process involving monoester formation followed by conversion to the diester. Reaction conditions, catalysts, and purification methods may vary by process.
For applications requiring lower volatility, DINP-based plasticizers such as VESTINOL® 9 DINP may be used. For enhanced durability and weathering resistance, ChemFlexx DPHP is also specified in certain applications.
Supplied by The Chemical Company as a ChemFlexx DOP distributor, this product supports consistent supply for general-purpose plasticizer applications.
