Bis(2-ethylhexyl) cyclohexane-1,4-dicarboxylate; (DEHCH)

Diethyl hexyl cyclohexane-1,4-dicarboxylate (DEHCH) is a premium eco-friendly non-phthalate plasticizer and can be used for various applications in contact with people, which include all of the flexible PVC products including toys, medical and food-contact materials. DEHCH is miscible and compatible with all of the monomeric plasticizers commonly used in PVC, and PVC-formulation can be mixed with the monomeric plasticizers.

Compared to other (non)phthalate plasticizers, DEHCH shows similar processability to DOP, viscosities similar to DINCH, stronger weather resistance than DOP, shorter gelation speed than DOTP and DINCH and similar plasticization efficiency to DINP.
