Research progress of novel bio-based plasticizers and their
Many bio-based PVC plasticizers, such as vegetable oil-based plasticizers, cardanol-based plasticizers, lactic acid-based plasticizers, waste cooking oil-based plasticizers, polyester plasticizers, hyperbranched plasticizers and so on, have been extensively studied.
Sustainable Micro and Nano Additives for Controlling the Migration of a
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.

Preparation and Performance of Bio-Based Polyol Ester
This study focused on the synthesis of a bio-based plasticizer using castor oil as raw material via a simple and efficient one-pot method, and on the investigation of the toxicity of bio-based plasticizer and performance of plasticized PVC films.
- What is the migration kinetic mechanism of plastic stabilizers?
- At high contact temperature (40 °C for PLA and 60 °C for PP), the migration kinetic mechanism of stabilizers from plastics with no plasticizer content is very similar to that of plastics with 10 w % TBAC at low contact temperature (20 °C for PLA and 40 °C for PP). For example, BHT shows this behavior in case of both polymers.
- Does plasticizer affect the migration of additives?
- The results confirm that the presence of plasticizer in the plastics enhances swelling, and thus the migration of additives. The plasticizer content is in strong correlation with migration rate for all additives, except for PLA-Irgafos 168 samples.
- 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.
- 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.
- Why do plasticizers have a polymer chain mobilizing effect?
- The explanation of this phenomenon is that plasticizers have a polymer chain mobilizing effect, which highly depends on the amount of plasticizer in the plastic. Because of the increased chain mobility, the diffusion of small molecules – i.e., plastic additives – is better facilitated. Fig. 2.
- How does temperature affect the plasticiser migration process?
- In addition, other ageing processes, such as the oxidation and annealing of polymers, are also accelerated at high temperature. 50 Any effects of these processes on the plasticiser migration process should be determined to yield a correct prediction.
