Courtesy of Todo en Polímeros.### PVDC is a synthetic polymer with exceptional barrier properties. It has transformed industries such as food packaging and medical products. Polyvinylidene Chloride is an essential polymer for protective barrier applications. Its versatility and ability to protect against moisture and contamination allow PVDC to play a fundamental role in the plastics industry. **You can also read:**[Inside Materials – PVC](https://www.plasticsengineering.org/2024/09/inside-materials-pvc-006603/) ## **Understanding Polyvinylidene Chloride** Manufacturers obtain this polymer through the polymerization of vinylidene chloride. Its molecular structure includes two chlorine atoms per repeating unit. This structure imparts unique properties, such as a notable barrier against gases and liquids. Additionally, it provides high chemical resistance and flame retardancy. These characteristics make PVDC ideal for applications where protection is crucial. The table above presents the average properties of PVDC, offering insights into its material characteristics. The following abbreviations are used for clarity: A = Amorphous, Cr = Crystalline, C = Clear, E = Excellent, G = Good, P = Poor, O = Opaque, T = Transparent, R = Rockwell, S = Shore.

They employ various processes to manufacture these different forms. It includes blown film extrusion, cast film extrusion, coextrusion, extrusion coating, solution coating, and injection molding. Each method leverages the properties of Polyvinylidene Chloride to meet specific requirements across various applications. ## **Pursuing Sustainability in PVDC Development** In the realm of innovations, developers have prioritized sustainability in developing PVDC. For example, Solvay has developed DIOFAN ULTRA 736, a PVDC coating that resists high water vapor and uses thinner layers. This innovation enhances performance and reduces the carbon footprint of pharmaceutical blister films. This achieves a more compact and sustainable design.
