PVC can be modified by including various additives that improve its performance, for instance, at high temperatures or by increasing the flexibility of the wires. All these applications call for electrical cables for domestic and industrial use provided or catered to by PVC.

Q: What distinguishes flexible PVC from regular PVC in cable usage?

A: Flexible PVC, as it is called, can be described as plasticized PVC because it has additives that allow more flexibility than standard PVC. This qualifies it for the situation when, for instance, a cable has to be used within the equipment that allows it to be flexed or turned about. Flexible PVC is commonly used for lead wires, portable cords, and other more flexible components. In contrast, standard PVC contains a larger concentration of thickening agents and so is much stiffer, thus it is most suitable for use in fixed wiring systems where flexibility is not much of an issue.

Q: What voltage rating do PVC insulated cables have?

A: The voltage rating of PVC insulated cables depends on the insulation’s specific formulation and thickness rating. In most cases, PVC insulated cables are used for low—and middle-voltage applications between 300 and 1000V. However, specially formulated PVC compounds can be used for higher-voltage cables up to several kilovolts. Depending on the application, specific types of PVC insulation suitable for particular voltages should be used.

Q: About high-temperature environments, How does PVC work?

A: Apart from the specially designed plastic used in the plumbing, standard PVC has limitations in high-temperature environments, typically performing well up to approximately seventy degrees Celsius or 158 degrees fahrenheit. In the case of specially formulated PVC compounds incorporating heat stabilizers, higher temperatures of functioning at 105 degrees Centigrade or greater up to even higher levels during short periods is achieved. Polyethylenes or fluoropolymers may be more suitable for applications requiring consistent high-temperature resistance than PVC.

Q: What is the difference between PVC and vinyl in wire insulation?

A: Several customers have asked whether it is appropriate to refer to wire insulation as PVC and vinyl, so there is no such thing as cable insulation made from vinyl. The answer here is tricky. Vinyl is a condensed form of polyvinyl chloride, better known as PVC. Both terms are used in the same way as vinyl, which refers to the same polymer made of vinyl chloride monomer units. The confusion sometimes appears because ‘vinyl’ refers to other polymers in other situations, but PVC and vinyl are mostly synonymous in wires and cable membranes.

Q: Are there any environmental concerns associated with PVC cable insulation?

A: Concerns arise mostly because of the abuse of PVC cable insulation. Since PVC entails chlorine, dioxins can be formed.
