Epoxidized soybean oil
ESBO is one of the additives in the PVC gasket. It serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally, e.g. when the gasket is applied to the lid and food product undergoes sterilization. [5] ESBO is also used in PVC cling films for wrapping foods and toys. Safety [ edit] Food [ edit]
Performance evaluation of new plasticizers for stretch PVC
The carbonyl group absorption frequencies of the ester plasticizers can be shifted to frequencies several wave numbers lower (lower energy) when the ester group interacts with the PVC [1]. This band shift was observed for samples 3 and 5 (displacement of 4 cm 1 lower), indicating higher interaction between the plasticizers and the PVC resin
Plasticizers: Types, Uses, Classification, Selection & Regulation
Suspension PVC (S-PVC) process is the common method to manufacture PVC: PVC obtained in the form of particles with size 50-200 microns Lower flexible PVC formula costs PVC particles obtained are mixed with plasticizers & can be extruded in pellets which are further used for processing via extrusion, calendaring, injection molding…
Epoxy Esters - Plasticisers - Information Center
Epoxy Esters. Epoxy plasticisers are esters containing an epoxy group such as epoxidised soybean oil (ESBO) or epoxidised linseed oil (ELO). They are formed by the epoxidation of an olefinic double bond to an oxirane structure. These plasticisers are used to improve heat stability in the production of PVC articles made by techniques such as
Plasticizers > Epoxidized Oils (ESBO, ELO)
Vikoflex 9080 Epoxidized Vegetable Oil. Vikoflex 9080 Epoxidized Vegetable Oil by Cargill acts as a plasticizer, stabilizer and acid scavanger. It is based on epoxidized linseed fatty acid ester. It improves low temperature properties of flexible PVC.
- 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 cardanol based plasticizers be combined with epoxidized soy bean oil?
- Although cardanol-based plasticizers including cardanol acetate (CA) and epoxidized cardanol acetate (ECA) have individually been studied on their plasticization effects for PVC as well as thermal and leaching stabilities, the combinational use of cardanol based-plasticizers with epoxidized soy bean oil (ESBO) has not previously been investigated.
- Can epoxidized palm oil be used as a plasticizer for PVC?
- On the contrary, epoxidized palm oil is among the least used, because of its low compatibility with PVC. This work reports that epoxidized and esterified palm kernel oil (EEPKO) has the potential to be used as a plasticizer for PVC. In this study, it was found that a maximum of 65 phr of EEPKO could be incorporated within the PVC resin.
- Is acetylated castor oil a bio-based plasticizer?
- Although acetylated castor oil has excellent performance as the bio-based plasticizer and has realized industrialized production, the price of it is three to four times more expensive than phthalates, which limited its utilization (Bocque et al., 2016).
- Which plasticizer has flame retardant properties?
- Jia et al. invented a soybean-oil-based plasticizer containing phosphaphenan-threne group and the PVC with this plasticizers has flame retardant properties . Liu et al. reported that a green plasticizer was synthe-sized from lactic acid, and the plasticizing performance of this plasticizer was better than ATBC .
- Can Esbo be used as a secondary plasticizer?
- Thus, to investigate the synergetic effects of combining DOP or cardanol-based plasticizers with ESBO as a secondary plasticizer, 5 phr of ESBO was added to each sample of PVC/DOP (50), PVC/CA (50) and PVC/ECA (50). The Young's modulus and tensile stress of all PVC/DOP (50)+ESBO (5) and PVC/CA (50)+ESBO (5) samples were improved.
