Application
DPGDB is a high solvating Dibenzoate plasticizer. As a replacement for phthalate plasticizers recommended by the European Chemical Agency (ECHA), it has been used for many years in a wide variety of applications, including adhesives, PS sealants, caulks, resilient flooring, PVC, artificial leather cloth PVC coated cloth, paints, inks, pesticides, etc..

Product Advantages

Environmentally friendly plasticizers recommended by the European Chemical Agency ( ECHA ).Does not contain any phthalates and can be used as a main plasticizer.
High solvating. Low fusing point which means faster processing speed. Very good foaming effect in PVC foaming process.
Very good plasticizing effect which means more fillers can be added. In PS sealants formulations, compared with traditional plasticizers, DPGDB added can be reduced by around 15%.
Compatible with compounds. Products containing DPGDB exhibit excellent stain and extraction
resistance. Soft under low temperature. Impervious to light and heat. Low VOC content.

Packing and Storage
Packing  :  In 225kg net iron drums.
Storage  :  Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Safety Information
