Polyvinyl chloride in consumer and environmental plastics
Introduction Polyvinyl chloride (PVC) is a vinyl polymer with the chemical formula (C 2 H 3 Cl) n whose key properties are given in Table 1.First patented in 1913 and commercially produced in 1933, this thermoplastic has had widespread uses in various sectors because of its durability, inherent flame retardancy, excellent chemical and mechanical properties and ability to accommodate a wide
Polyvinyl chloride
Polyvinyl chloride (alternatively: poly (vinyl chloride), [6] [7] colloquial: polyvinyl, or simply vinyl; [8] abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene ). [9] About 40 million tons of PVC are produced each year.

Thermal Analysis of Polyvinyl Chloride - Influence of Plasticizer on Glass Transition - 1. Introduction Polyvinyl chloride (PVC) is used as an all-purpose plastic in a wide variety of fields ranging from industrial materials such as pipes and wire coating materials to general consumable materials such as film and sheets.
- What is plasticized polyvinyl chloride (PVC)?
- Plasticized polyvinyl chloride (PVC) films were prepared by melt compounding and compression molding using epoxidized cardanol (EC), a biobased plasticizer and its plasticization effect was compared with epoxidized soybean oil (ESBO) and dioctyl phthalate (DOP).
- Can plasticizer improve the plasticity of polyvinyl chloride (PVC)?
- Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
- Is plasticized polyvinyl chloride harmful?
- However, an application of common plasticized polyvinyl chloride (pPVC) is accompanied by an adverse phenomenon, specifically by the non-negligible and potentially harmful migration of plasticizers into the surrounding media as they are not covalently bound to PVC.
- What is the relationship between plasticizer and PVC?
- The higher the binding energy is, the stronger the interaction between plasticizer and PVC is, and the more difficult it is for plasticizer to migrate out of the PVC system. In plasticized PVC system, its expression is as follows:
- What happens when plasticizers are introduced into PVC gel?
- The introduction of plasticizers into PVC results in a transition from rigid PVC (solid) to soft PVC gel (colloid). In pure PVC gel, the PVC molecular chains form the internal network skeleton, restrict the migration of plasticizers, and provide a stable cross-linked structure .
- What is soft PVC?
- PVC-P or soft PVC refers to PVC with plasticizer molecules embedded between the polymer chains with plasticizer contents of 20 to 50%. The letter P stands for plasticized. The toughness and flexibility of PVC-P varies with the kind of plasticizer. Plasticizer migration out of PVC-P after aging can result in fogging or embrittlement of the polymer.
