Methyl Acetyl Ricinoleate as Polyvinyl Chloride Plasticizer
In this study, an additive derived from castor oil (methyl acetyl ricinoleate—MAR) was tested as a plasticizer for PVC. MAR was added to PVC in a range of 50–90 PHR and the increase of the plasticizer content had a great effect on maximum tension and tension at 100% of PVC samples.
Application of Different Vegetable Oils as Processing Aids
Siwarote et al. (20) have investigated the suitability of three different vegetable oils (tea oil, palm oil, and coconut oil) as a plasticizer in silica-filled NR composites. For comparison, the authors have used petroleum-based naphthenic oil (NTO) as a reference.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Role of the Oxethyl Unit in the Structure of Vegetable Oil
Owing to the excellent plasticization of DA-8, the performances of PVC-DA-8 were comparable or better than that of the PVC plasticized using commercial dioctyl terephthalate (DOTP). The simple but efficient method of this study provides a new avenue for the preparation of vegetable oil-based plasticizers for PVC.
Green plasticizers derived from epoxidized soybean oil
General, plasticizers are added into PVC to improve the thermal, mechanical and flame-retardant properties [2]. Nowadays, there are more than 500 kinds of plasticizers in the market. Among them, phthalate plasticizers dominate the main commercial plasticizers [3]. These phthalate plasticizers are derived from petroleum resources.
- Can vegetable oils replace phthalate plasticizers?
- Although phthalate plasticizers have been widely utilized for decades, there is mounting evidence that vegetable oils (VOs) can serve as a safe, effective alternative to phthalates (Fu et al., 2019).
- Can waste cooking oil be used as a plasticizer?
- This paper reported the preparation of a renewable plasticizer originated from waste cooking oil (WCO). The plasticizing effect of the developed material on the properties of poly (vinyl chloride) (PVC) was studied.
- Can epoxidized soybean oil be used as a plasticizer for PVC?
- Compounds derived from vegetable oil have been widely used as a plasticizer or secondary thermal stabilizer for PVC. For example, the effect of epoxidized soybean oil (ESO) as a plasticizer on the mechanical and thermal properties of PVC has been studied [Bouchareb and Benaniba, 2008].
- Is WCO a good alternative to edible oil for PVC plasticizers?
- However, these raw materials, i.e., the edible vegetable oils, are in short supply in some developing countries, thus hampering the wide application of such green plasticizers. As an alternative, WCO is regarded as a good resource instead of edible oil to produce plasticizers for PVC, especially in some developing areas.
- What are bio-based plasticizers?
- Bio-based plasticizers may be produced from agricultural by-products and wastes, including cardanol derivatives, starches, cellulose, citric acid, and bio-based waste, which are renewable, abundant, and economical resources. The majority of them have been employed as raw materials in the production of plasticizers [3, 22].
- Which vegetable oils are good replacements for DINP in PVC?
- Bondeson studied the epoxidation of vegetable oils such as soybean, sunflower, and safflower are good replacements for DINP in PVC materials used for indoor applications. 95 Moreover, the rate of crosslinking is positively correlated with the degree of epoxidation of the epoxidized vegetable oils.
