Diethylhexyl 2,6-naphthalate

Diethylhexyl 2,6-naphthalate (CAS 127474-91-3), also known commercially as CORAPAN TQ, is a naphthalate-based plasticizer used in polymer processing to improve flexibility and processability.

Where is Diethylhexyl 2,6-naphthalate used?

• Flexible PVC compounding: primary plasticizer with low-temperature flexibility and reduced volatility versus standard phthalate esters
• Packaging films and laminates: low migration, seal integrity, food-contact or sensitive-end-use requirements
• Printing and packaging substrates: ink adhesion and film performance in coated or printed flexible materials
• It is also evaluated in specialty polymer blends for long-term use.

Good to know: Unlike conventional phthalate plasticizers, it offers a non-phthalate alternative where regulatory compliance or migration performance is a formulation priority.
