An efficient plasticizer based on waste cooking oil
The test to assess the ease of migration of the plasticizer from the flexible PVC films was carried out using five different solvent media, namely, distilled water, 10% (v/v) ethanol, 30% (w/v)...
WCO CAN BE MADE INTO PLASTICIZER - News - Zhejiang Jiaao
The strategy of biodiesel production from WCO with low price about internally plasticized PVC materials from WCO is one of the best ways to utilize it efficiently and economically. Plasticizer is an important polymer additive, which has been widely used in plastics, rubbers, adhesives, cellulose and so on.
Plasticizers: Types, Uses, Classification, Selection & Regulation
PVC particles obtained are mixed with plasticizers & can be extruded in pellets which are further used for processing via extrusion, calendaring, injection molding… Processing equipment is typically very expensive Incorporation of an external plasticizer in PVC polymer enhances its flexibility.
- Can WCO be used as a plasticizer for PVC?
- As an alternative, WCO is regarded as a good resource instead of edible oil to produce plasticizers for PVC, especially in some developing areas. Similar to structural modification of vegetable oil, reducing the degree of the –C C- unsaturation is still the main approach [Jia et al., 2018; Zheng et al., 2018; Feng et al., 2018].
- Can WCO be used for preparing internal plasticizer?
- However, WCO can be used for the preparation of fine chemicals such as internal plasticizer. With this aim, this work is focused on preparing internal plasticizer by using WCO and determining technical viability of non-migration poly (vinyl chloride) (PVC) materials.
- Does epoxidized WCO plasticizer provide better compatibility with PVC?
- While the production of epoxidized WCO plasticizer was reported, very limited information was available on the introduction of epoxy groups to the ester bond in WCO. It is expected that WCO-based plasticizer with a higher epoxy value could provide better compatibility with PVC.
- How are WCO-based plasticizers synthesized?
- Most WCO-based plasticizers were synthesized by a conventional epoxidation approach, where the –C C- bond was converted to the epoxy group with the assistance of peroxy acid. Compared with internal oxirane, the terminal epoxy group in plasticizer enhanced the plasticizing effect and thermal stability of PVC [Chen et al., 2017].
- 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.
- Does waste cooking oil make a plasticizer?
- These findings transformed the traditional plastic processing technology and obtained cleaner production of no migration plasticizer from WCO. Waste cooking oil (WCO) is an oil-based substance, which has been used to make foods, but no longer suitable for eating.
