Diethyl hexyl cyclohexane（DENCH）

Diethyl hexyl cyclohexane（DENCH）

DEHCH is the product with the closest physical properties to DOP among existing plasticizer products. Compared to DOTP, DEHCH features faster absorption speed, shorter plasticization time, and higher plasticization efficiency (with lower product hardness under equal usage conditions). It excels in terms of product transparency, initial coloring, and migration resistance. It can be used in PVC soft products such as PVC flooring, PVC decorative wallpaper, and transparent sheets.
