28553-12-0

Product Type

Additive > Plasticizers additive > Phthalates

Recommended for

Polymer > PVC

Applications

Adhesives

Producer

Evonik

Supplier

Evonik Iran

Chemical Composition

Di-iso-nonyl-phthalate

Advantages
  • give better cold flexibility and lower plastisol viscosity than DOP
  • The higher molecular weight of DINP also reduces plastisol thickening
  • has a wide variety of beneficial properties, both during processing and in finished products
Other Applications

Adhesives

Handling

VESTINOL 9 (DINP) can be mixed with any other commercially available plasticizer and is fully compatible with
PVC - even in highly plasticized formulations.
