Green Secondary Plasticizer/Thermal Stabilizer in PVC Processing
soybean oil is heavily used in PVC processing. Karmalm used an epoxidized soybean oil to form the network in plastisol PVC [12]. In another work of this author, the epoxidized soybean oil was used as primary plasticizer and the thermal stability of PVC was estimated by yellowness index, transmittance and chlorine analyses [13]. The epoxidized
Stabilization Studies of Epoxidized Soybean Oil Plasticized
First, optimum loading of epoxidized soybean oil (ESBO) in PVC matrix was determined as a substitute of di-octyl phthalate by increasing loading from 20, 40, 60, 80, and 100 phr of total plasticizer. The plasticizer was compounded with PVC resin on a two-roll mill at 170 °C.
Migration of epoxidized soybean oil from polyvinyl chloride
Epoxidized soybean oil (ESBO) has been used in polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) food packaging cling film as a plasticizer and stabilizer. The aim of this study was to investigate the migration of ESBO from PVC/PVDC cling film, based on gas chromatography mass spectrometry (GC
Epoxidized soybean oil
Epoxidized soybean oil ( ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid. [3] Manufacturing process [ edit] Epoxidized linolein, a major component of ESBO.
Effect of epoxidised soybean oil loading as plasticiser on
The aim of this paper is to study the effect of epoxidised soybean oil (ESO) as an alternative plasticizer on physical, mechanical and thermal properties of plasticised polyvinyl chloride...
- What is epoxidized soybean oil methyl ester (Esom) plasticizer?
- Herein, epoxidized soybean oil methyl ester (ESOM) plasticizer was synthesized for the preparation of plasticized poly (vinyl chloride) (PVC) films by the alcoholysis and epoxidation. The chemical structure of ESOM was investigated by infrared spectrum and 1 H nuclear magnetic resonance.
- 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.
- Can soybean oil based plasticizer improve PVC resin properties?
- The results indicated that soybean oil-based plasticizer could significantly increase plasticizing effect and improve thermal stability of PVC blends when partially of completely replaced DOP. Furthermore, EGESOFa could endow PVC resin with well-balanced properties of flexibility, strength, and hardness.
- What is epoxidised soybean oil (ESBO)?
- Epoxidised soybean oil (ESBO) is a commercially available bio-based plasticizer that is typically used at lower levels than traditional phthalates in PVC compounds because it does not show equivalent performance to existing phthalate plasticisers. Four derivatives of ESBO have been synthesized through reaction at the epoxide rings.
- Can soybean oil be used as a co-stabilizer for PVC?
- Epoxidized soybean oil indicated the excellent properties as a co-stabilizer for PVC when used in combination with the Ca/Zn stearates. The ternary system helped to improve plasticization effect and thermal stability of PVC compositions. Fly ash filled PVC system showed better thermal stabilization effect.
- What is epoxidized glycidyl ester of soybean oil fatty acids?
- A novel environmental soybean oil-based plasticizer, epoxidized glycidyl ester of soybean oil fatty acids (EGESOFa), was synthesized and characterized by Fourier transform infrared (FTIR), 1 H-nuclear magnetic resonance ( 1 H-NMR), and 13 C-nuclear magnetic resonance ( 13 C-NMR).
