In a recent study, Aouachria et al. (2019) evaluated the effects of acetyl tributyl citrate as bio-based plasticizer on the physical, thermal, and dynamical mechanical properties

In the last two decades, the use of phthalates has been restricted worldwide due to their well-known toxicity. Nonetheless, phthalates are still widely used for their versatility, high plasticization effect, low cost, and lack of valuable alternatives.

Because the commonly used phthalate plasticizers have adverse effects on the environment and health, there is a need to develop plasticizers with renewable material

On the other hand, these new bio-based plasticizers can also ameliorate mechanical and thermal properties of PVC like traditional plasticizers, and are eco-friendly, low priori toxic and resistant to migration. Thus, preparing high

How does temperature affect plasticizer migration kinetics?
The presence of this thin film of plasticizer that cannot easy evaporate due to the low temperature, limits the kinetic of plasticizer migration (the system will be evaporation-controlled). It is obvious that the concentration of plasticizer and the operative temperature will strongly influence the migration kinetics.
Which kinetics migration modes dominate plasticizer loss?
However, it must be pointed out that two kinetics migration modes dominate the plasticizer loss: the diffusion mode (above mentioned) and the evaporation mode [ 23 ]. Considering only the one-dimensional problem in the x-direction (similarly to Equation (5)), the evaporation condition can be described by the mass balance [ 54, 63 ]
What causes plasticiser migration in biopolymers?
Studies have shown that the migration behaviour of plasticiser in biopolymers is often complex. This is caused by: (i) cold crystallisation during service/ageing, (ii) phase separation between the plasticiser and the polymer, and (iii) hydrolysis and interactions with water.
Does operative temperature affect plasticization kinetics?
It is obvious that the concentration of plasticizer and the operative temperature will strongly influence the migration kinetics. Zhang et al. [ 65] demonstrated for a PLA system plasticized with acetyl triethyl citrate (ATC) that the ATC migration increases with the increasing of ambient temperature.
Do plasticisers migrate from polymers to a gas phase?
This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service temperature conditions and during accelerated ageing and testing.
How does plasticizer migration affect the quality and effectiveness of PVC?
The migration of plasticizers is a key factor that impacts the quality and effectiveness of the PVC, and the mass loss due to plasticizer migration in different environments is shown in Fig. 8.
