    Application:

    1.Environmentally friendly plasticizers recommended by the European Chemical Agency(ECHA) in May 2009.Does not contain any phthalates and can be used as primary plasticizers.Data from more than 30 years applications and tests show Dibenzoate esters are low in toxicity,non-mutagenic,non-carcinogenic and easy to degrade.

    2. High solvating and lower fusing point which means faster processing speed.Verygood foaming effect in PVC foaming process.

    3.High plasticizing efficiency.More fillers can be added.In some formulations there is an apparent decrease of plasticizer volumn.
    4.Compatible with compounds like PVC,EVA,etc..Products containingDipropylene Glycol Dibenzoateexhibit excellent stain and extractionresistance.Soft underlow temperature.Impervious to light and heat.Low VOC content.
