Epoxidized Soybean Oil - an overview | ScienceDirect Topics
ESBO and epoxidized linseed oil are used as lubricants and costabilizers to improve heat stability of PVC articles, paints, and coatings. At high concentrations, there are risks of development of incompatibility with PVC during aging, leading to migration and tacky surfaces in the presence of sunlight.
Effect of the individual and combined use of cardanol-based
Currently, the most widely used commercial plasticizers are phthalate compounds, for example dioctyl phthalate (DOP); however, these phthalates easily migrate to external media causing deterioration of PVC products.
Catalytic developments in the epoxidation of vegetable oils and the
Functionalization of vegetable oils (VOs) including edible, non-edible, and waste cooking oil (WCOs) to epoxides (EVOs) is receiving great attention by many researchers from academia and industry because they are renewable, versatile, sustainable, non-toxic, and eco-friendly, and they can partially or totally replace harmful phthalate plasticizers.
Acrylated soybean oil: a key intermediate for more sustainable
We report that the amount of silicone, per application, can be significantly reduced by the creation of silicone composites derived from soybean oil. Acrylated soybean oil, prepared by addition of acrylic acid to epoxidized soybean oil, was linked to aminoalkylsilicones using a catalyst-free aza-Michael reaction in the absence of solvents; the
Research progress of novel bio-based plasticizers and their
The resulting epoxy tung oil methyl ester (ETM) and tung-oil-based epoxy plasticizer (TEP) showed better thermal stability and solvent resistance than DOP. Plasticizing efficiency of ETM and TEP reached 104.1% and 101.5%, respectively.
- 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 epoxidized soybean oil be used as a substitute for di-octyl phthalate?
- Reaction mechanism of epoxidized soybean oil 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.
- 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.
- 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.
- 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.
- Can beta-diketone Stabilizers improve epoxidized soybean oil Plasticized PVC films?
- The success of the novel beta-diketone stabilizers can meet higher performance and longer service life of epoxidized soybean oil plasticized PVC films in the presence of zinc and calcium stearates. This will eventually lead to a positive impact on the environment.
