Nowadays, it seems like there are few research conducted in the study of PVC plastisol.
Actually, there are few papers about the study of PVC plastisol because it is an extremely dangerous product. PVC plastic is the second most used and most damaging to the environment. Its production uses a dangerous and explosive substance such as vinyl chloride monomer (VCM) and it produces ethylene dichloride (EDC) as toxic waste.
His formulation include plasticizers (phthalate DEHP), pigments, heavy metals, fungicides, etc.. During use these phthalates, PVC transfers to the environment.
For example if a child chew or suck on toys or stamping PVC (plastisol) of his shirt can ingest these substances. So you are banned since 2005 by the European Community.
The PVC plastisol too, being incinerated or accidentally delivered tetra chloro dibenzo generates dioxin TCDD (C12H4Cl4O2), the most lethal form of the dioxin family, is a known human carcinogen and hormone disrupter and is recognized as the most toxic synthetic compound produced.
The solvents used for the PVC blend, are carcinogenic and harmful to the environment, particularly when they evaporate or contaminate food.
These solvents are released into the environment during printing and curing of plastisol and will escape when the print is exposed to a radiant heat source, like a hair dryer or even sunlight.
Plastisols based on polyvinyl chloride (PVC) can be processed by different techniques; their processability markedly depends on their flow properties and gelation/fusion processes. Classically, PVC has been the only polymer present in plastisol formulations. The present work explored the possibility of adding polyhydroxyalkanoates (PHAs), a type of biopolymer that, according to previous work, exhibits a good miscibility with PVC processed by other techniques (internal mixer and compression molding). The influence of PHA particles on flow properties, gelation-fusion processes, tensile strength, hardness, and processability by rotomolding was evaluated. Although the biopolymer markedly increased the viscosity of PVC plastisols and caused a decrease in tensile strength in processed specimens, formulations including 20% by weight of biopolymer presented a good thickness distribution in rotomolded items, an elongation at break of around 300%, and an ultimate tensile strength of around 6–7 MPa.

It is unfortunate but PVC is still widely used in the building industry. Because of its versatility, PVC is found in plumbing pipes, electrical wiring, windows frames and jambs, carpet, and wall covering to name a few. PVC also uses large amounts of chlorine during its manufacturing process. And is the only plastic that uses chlorine as a major component . We should also be very concerned with Dioxins as a by-product of the PVC's manufacturing process.
