Diisononyl phthalate (DINP) is a phthalate used as a plasticizer.
DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.
DINP is a mixture of isomers that have alkyl chains from 7 to
9 carbons long, but the largest portion of the mixture have chains composed of
8-carbon in length (a.k.a. isononyl alcohol).
The
European Union has set a maximum specific migration limit from food contact materials of 9 mg/kg food for the sum of
diisononyl phthalates anddiisodecyl phthalates.
DINP
is almost colourless and odourless oily liquid, free of foreign materials which
0 is slightly soluble in water ( 0.285mg/L at 24 C ) but soluble in alcohols,
hexane etc. It is miscible and compatible with all the monomeric plasticizers
of PVC compounding.
Around 95% of DINP is used in PVC as a plasticizer. More than half of
the remaining 5% is used in the production of polymers other than PVC
(e.g.rubbers). The remaining DINP used in non-polymer application including
anticorrosion paints, anti-fouling paints, lacquers, inks, adhesives and
sealants.
DINP
is a monomeric primary plasticizers of medium molecular weight and fine
performance. It has been developed to fulfill the need for an economical
plasticizer in formulation which require very low volatility and good
permanence characteristics. This products is widely used in vinylic compounds
including wires, cables and plastisols.
Diisononyl Phthalate (DINP) C6H4(COOC9H19)2, is a clear,
colorless, and almost odorless liquid chemical. It is soluble in most organic
solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the
low volatility and better endurability of DINP significantly reduces the fume
emissions during the processing procedure and improves its permanence in the
final product.
Plasticizer Overview
Plasticizers are polymer additives that serve to increase the
polymer’s flexibility, elongation and ease of processing. In other words, they
make the polymer more workable. In technical terms, the addition of a
plasticizer generally causes a reduction in the cohesive intermolecular forces
along polymer chains. The chains can then move more freely relative to one
another, hence reducing the stiffness of the polymer.
The use of plasticizers began in the mid 1860s when
castor oil was added to Cellulose Nitrate. The most commonly measured physical
effects include melt viscosity, elasticity modulus, and the glass transition
temperature. Other types of plasticizers have been used through the years, but
in the late 1930s, phthalates were introduced because they were believed to be less toxic. The two most common
plasticizers used today are di-2-ethylhexyl phthalate (DEHP) or DOP/ DiocthylPhytalate and di-isononyl phthalate (DINP), both of which are generally used in
the manufacture of PVC related products.
