Is DINP the same plasticizer as DOP or DOTP?

No. DINP, DOP and DOTP are different plasticizers with different CAS numbers, molecular structures and regulatory positions. A PVC compound should compare them by processing behaviour, volatility, flexibility target and the compliance requirement of the destination market.

What should be confirmed before ordering DINP for PVC compounding?

Confirm the required colour, ester value or assay basis, acidity, moisture, density, viscosity, volatility, packaging and regulatory declaration. These points give a clearer purchase specification than requesting DINP by CAS number only.

Which packaging is normally used for industrial DINP?

DINP is commonly supplied as a liquid in steel drums, IBCs or bulk tanks. The suitable pack depends on order volume, discharge method, storage conditions and transport requirements for the destination.

Product Description

Diisononyl Phthalate (DINP) CAS 28553-12-0 is phthalic acid diisononyl ester, with molecular formula C26H42O4.

Synonyms: Diisononyl phthalate; DINP; phthalic acid diisononyl ester; diisononyl benzene-1,2-dicarboxylate.

CAS: 28553-12-0.

Molecular formula: C26H42O4.

It is normally supplied as a clear oily liquid.

It is used as a high-molecular-weight plasticizer in flexible PVC compounds.

It is used in PVC cable and wire compounds, flooring, wall covering and artificial leather.

It is also used in coated fabric, tarpaulin, film, sheet, sealant and plastisol formulations.

Performance depends on the PVC resin, stabilizer package, processing conditions and target-market requirements.

Grades are selected by colour, ester value, acidity, moisture, density, viscosity and volatility.

DINP is not the same plasticizer as DOP or DOTP.

Confirm colour, ester value, acidity, moisture, density, viscosity, volatility and the applicable regulatory declaration.

For purchasing, specify the intended PVC application, required liquid specification, packaging and destination requirements.

Keep containers closed and follow the current SDS for storage and handling.

Use suitable PPE and exposure controls when handling the material.

Confirm colour, ester value, acidity, moisture, density, viscosity and volatility on the COA.

Confirm grade, packaging, and specification as required.
