Diisononyl phthalate(DINP)

CAS: 68515-48-0

Diisononyl phthalate (CAS:68515-48-0), The IUPAC name of Diisononyl phthalate is bis(7-methyloctyl) benzene-1,2-dicarboxylate. With the CAS registry number 68515-48-0, it is also named as Di(C8-10, C9 rich) branched alkyl phthalates. The product's categories are Plasticizers; Polymer Additives; Polymer Science. It is colorless transparent liquid which is insoluble in water, compatible with PVC, polystyrene and vinyl chloride - vinyl acetate copolymer, partially compatible with polyvinyl acetate, cellulose acetate butyrate and cellulose nitrate, and incompatible with ethyl cellulose and cellulose acetate, methyl acrylate resin. In addition, Diisononyl phthalate is a phthalate used as a plasticizer.

introduction

Application industries:

· DINP's volatilization weightlessness is smaller than DOP. Intrinsic viscosity is similar to DOP. You will get a more high viscosity value if use DINP alone.

· DINP is suitable for the plastic production, proving stable viscosity and no problems exist during disperse foaming. The melting temperature is low. As the PVC coating, DINP has the lowest viscosity and the change in viscosity quite small.

· Mainly used to PVC, and also widely used to toys' film, wire and cable since DINP has good water proofing,

extraction resistance, electric insulating property and low-poisonousness.
