Vestinol 9 Di-iso-nonyl-phthalate 28553-12-0 Degussa-Oxeno Olefinchemie Plasticizers >> Phthalate Polyvinyl Chloride (PVC) ADHESIVE Di-isononyl phthalate (DINP) The advantageous properties of the plasticizer VESTINOL 9 (DINP) are apparent in every method of thermoplastics processing, and also in the processing of plastisols, as well as in the performance of the finished products. This n-butene-based low-branched grade is known to give better cold flexibility and lower plastisol viscosity than DOP. The higher molecular weight of DINP also reduces plastisol thickening. VESTINOL 9 (DINP) can be mixed with any other commercially available plasticizer and is fully compatible with PVC - even in highly plasticized formulations. In summary - VESTINOL 9 (DINP) has a wide variety of beneficial properties, both during processing and in finished products, making this the plasticizer of choice for PVC applications. Di-isononyl phthalate (DINP). Used as a plasticizer for PVC applications. Gives cold flexibility and low plastisol viscosity. Reduces plastisol thickening.
