Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
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.
- Is WCO a viable replacement for petroleum based plasticizers?
- WCO has also been effectively used for the production of plasticizers and used as additives in the plastic industries, food packaging and toys manufacturing. Increased demand for plasticizers in the last decade and the negative effects of petroleum-based plasticizers has made the search for a viable replacement inevitable.
- 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].
- 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 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.
- 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.
- Are WCO plasticizers safe?
- Further, Huzaizi et al. , Feng et al. and Liu et al. have produced plasticizers from WCO and reported that the plasticizers produced from WCO are safer, non-toxic and exhibit better overall mechanical and thermal properties than petroleum-based plasticizers.
