to those of DOP p conclusion that BE can be used as a co ESBO upto wt. 65% to replace DOP. ABSTRACT Studies showed that phthalate plasticizers are carciogenic. The concerns raised about toxicity led to a large demand of producing non- toxic and bio- based plasticizers. Currently, ESBO can only replace 30% DOP in the PVC formulations.

This plasticizer can replace up to 25 wt% of primary plasticizer such as DOP. 37 Concentration of epoxy plasticizer can be farther increased to 70 phr by tailoring its chemical structure to the required performance. 38 Glycidylethylhexylphthalate was synthesized and its performance was evaluated. 97 The plasticizer was designed to act like normal
CONTRIBUTION OF EPOXIDIZED SOYBEAN OIL IN PVC
It is better to replace DOP with ESBO, as there is no antiplasticization. Besides, for every Phr of DOP the VST is reduced by 3.5 deg C per Phr as against 1.5 deg C for ESBO. It is always...

plasticizer for pvc epoxy oil to replace dop non-toxic
Another vegetable based plasticizer is epoxidized soybean oil (ESBO), a kind of renewable oil with viscosity 35 cPs; it has been long known as secondary plasticizer and a secondary stabilizer in PVC. ESBO is available with iodine value as low as 1 g l2/100 g, i.e. ≈ 0.04 mol double bonds in each molecule of ESBO.
- Can epoxidized soybean oil be used as a plasticizer for PVC?
- This study showed that epoxidized soybean oil (ESBO) could be used as a primary plasticizer for PVC. They can be used to replace DOP up to 100%. Epoxidized soybean oil indicated the excellent properties as a co-stabilizer for PVC when used in combination with the Ca/Zn stearates.
- Does dibenzoylmethane stabilize epoxidized soybean oil (ESBO) Plasticized PVC?
- The present work focuses on the development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of calcium/zinc stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM). The DBM which has dual property of a UV stabilizer and heat stabilizer was varied from 0 to 10 phr.
- Is dibenzoylmethane a UV stabilizer & heat stabilizer for epoxidized soybean oil?
- Hence, the present work focused on development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of zinc and calcium stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM) which has dual property of a UV stabilizer and heat stabilizer.
- What is the FTIR spectra of ESBO Plasticized PVC formulations?
- FTIR spectra of ESBO (20 phr) plasticized unfilled and fly ash (20 phr) filled PVC formulations after 100 h exposed to the accelerated QUV weathering condition in the presence of zinc and calcium stearates and in the presence of DBM (1.5–10 phr) are shown in Fig. 9 a–b, respectively.
- What determines the efficiency of ESBO?
- The efficiency of ESBO is decided by the number of epoxy groups in the molecule, as the formation chlorohydrins due to the facile reaction of HCl with epoxy groups which results in the reduction of the autocatalytic effect of HCl.
