Polyvinyl chloride, or PVC, is a widely-used synthetic thermoplastic polymer used in countless applications, from plumbing pipes to signage to phonograph records. PVC is also commonly used as a replacement for rubber materials.
PVC is made from 57% chlorine and 43% carbon. As such, it is less dependent on nonrenewable carbon-based resources, such as crude oil, than other similar polymers. This helps give PVC an excellent cost-to-performance ratio and makes it easy to recycle.
Advantages of PVC
- Very dense and very hard
- Resists impact deformation better than most other plastic
- Exhibits good tensile strength
- Inexpensive and readily available
Properties of PVC
PVC is produced in two types: flexible and rigid. In general, PVC exhibits high hardness and good mechanical properties. Those mechanical properties improve as the material’s molecular weight increases, but suffer in elevated temperatures. Rigid PVC’s elastic modulus can reach 3,000 MPa; flexible PVC’s elastic modulus is 1.5 to 15 MPa.
PVC exhibits good resistance to a variety of chemicals, acids, alcohols, bases, fats, and salts. It also exhibits resistance to some solvents, fuels, and paint thinners; some solvents may only swell or deform PVC, while others will dissolve it completely.
