Polymers | Free Full-Text | The Impact of Plasticizer and
Two model plasticizers were studied: propylene glycol and glycerol. Figure 1 shows the impact of propylene glycol on the cavity radius, R, and I3 in PVA. It can be seen that R increases linearly with concentration, showing the increasing cavity radius upon plasticizer inclusion.
Natural-based plasticizers and biopolymer films: A review
Natural plasticizers used in biodegradable films from biomass products (polysaccharide-, protein-, and lipid-based films) or other films obtained by extraction of micro-organisms. Refs. Soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) 6.1.
Preparation and Properties of Propylene Glycol Plasticized
A biodegradable film of wheat protein isolate (WPI) was prepared using Propylene Glycol as a plasticizer. Tensile strength and young’s modulus of the plasticized films were found to be decreased with increasing Propylene Glycol contents from 10 to 25 % where as % of elongation at break increased.

- Is propylene glycol a good plasticizer?
- Propylene glycol has been already proven to have good plasticizing properties (Ibrahim et al., 2020) and acids such as acetic acid, oleic acid and succinic acid can also act as plasticizers ( Chen et al., 2008; Qiao et al., 2021; Vlacha et al., 2016).
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- How is oleic acid and propylene glycol used in plasticizer synthesis?
- In the first synthesis step for both plasticizers, mono- and diesters of oleic acid and propylene glycol were obtained. In the second step, succinic acid was added. During reaction with propylene glycol, its succinate was produced (1.1 wt% and 0.6 wt% for KBOL and EPKBOL, respectively).
- Can glycerol be used as a plasticizer for chitosan films?
- Suyatma et al. (2005) studied the effects of ethylene glycol, propylene glycol, polyethylene glycol and glycerol on the mechanical and surface properties of chitosan films that were stored for 3 and 20 weeks. Glycerol and polyethylene glycol were found to be more suitable as plasticizers of chitosan than ethylene and propylene glycol.
- Which molecule has better plasticizing activity – oleic acid or propylene glycol?
- Therefore, it can be concluded that these compounds show better plasticizing activity than larger molecule like propylene glycol succinate, oleic acid, propylene glycol monooleate, propylene glycol dioleate or succinic acid, propylene glycol and oleic acid mixed esters. Fig. 6.
- How is OC plasticizer synthesized?
- OC plasticizer was synthesized from propylene glycol and acetic acid ( Fig. 1). The aim of this synthesis was to obtain as many monoesters of acetic acid and propylene glycol as possible, because they contain free hydroxyl groups which can interact with the hydroxyl groups of chitosan via hydrogen bonding (Chen et al., 2018 ).
