Simultaneous recovery of high-purity copper and polyvinyl
Plasticizers incorporated into the PVC matrix would increase and maintain the free volume to prevent interactions between neighboring polymer chains, which results in flexibility. 47 Thus, when the plasticizers are removed, the free volume of the PVC would be expected to decrease, resulting in shrinkage of the PVC covering.
Simultaneous recovery of high-purity copper and polyvinyl
As a result, PVC is used in a wide variety of fields including the construction, automobile, electrical, medical, and daily goods industries.1 The global production of PVC reached 41420 kt in 2015,2 making it the third highest in volume among plastic resins.

PLASTICIZATION THEORIES Lubricity Theory: Plasticizer acts as a lubricant, reducing intermolecular friction between polymer molecules responsible for rigidity of the polymer. Gel Theory: Polymers are formed by an internal three-dimensional network Free Volume Theory: Plasticizer lowers the glass transition temperature (Tg) of the polymer
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Does plasticizer type affect the equilibrium moisture content of films?
- Plasticizer type did not significantly affect the equilibrium moisture content of films. Sucrose added films were the most fragile at low RH, while GLY films were the most hygroscopic. However, at RH of 76–90%, sucrose films showed similar resistance compared to other plasticized films.
- Do plasticizer concentration and hydrophilic nature affect moisture affinity of cassava starch films?
- Plasticizer concentration and hydrophilic nature were found to be important factors in determining the moisture affinity of cassava starch films . GLY-containing films adsorbed more water and at a higher rate during their storage, compared to sorbitol films.
- What happens if a plasticizer exceeds a critical concentration?
- Above a critical concentration, the plasticizer can exceed the compatibility limit with the biopolymer, and phase separation with plasticizer exclusion is usually observed . Usually, biopolymers and plasticizers are hygroscopic and therefore film moisture content is affected by ambient conditions.
- What is a plasticizer in chemistry?
- The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
- What percentage of plasticizer demand is DOP?
- DOP represents 50% of world plasticizer demand Source BASF estimates Petrochemicals – Industrial Petrochemicals N-CPN/I The Heart of Your Products
