Diisononyl Phthalate (DINP)

Diisononyl Phthalate (DINP) appears as a clear, oily, viscous liquid with a faint ester odor. It is insoluble in water but highly compatible with organic solvents and common plasticizers.

DINP serves as an efficient, cost-effective alternative to traditional plasticizers like DEHP (DOP), offering superior low volatility, reduced migration, and enhanced long-term stability in flexible PVC applications.

Frequently Asked Questions (FAQs)

Q: What is DINP used for?

A: DINP is primarily a plasticizer for PVC, adding flexibility and durability to products like flooring, cables, automotive parts, roofing, and coatings.

Q: How does DINP compare to DEHP (DOP)?

A: DINP offers lower volatility, better heat stability, and reduced migration, making it a preferred replacement in many applications with similar or improved performance.

Q: Is DINP safe for use?

A: DINP has a favorable safety profile in regulated uses, with no harmonized reproductive toxicity classification in the EU. It complies with many global standards but is restricted in toys/childcare products in some jurisdictions. Consult current regulations for your application.

Q: Why choose DINP over other plasticizers?

A: Its combination of low volatility, good cold resistance, aging properties, and cost-effectiveness makes it a top choice for general-purpose flexible PVC.
