Which thermoplastic is the most widely used for cable jackets?

Polyvinyl chloride (PVC) is the most widely used thermoplastic for cable jackets due to its excellent properties for this application. PVC is chosen for its impressive durability, flexibility, and resistance to fire and abrasion, making it suitable for a wide range of environmental conditions. Additionally, PVC has good insulation properties and is cost-effective, which contributes to its popularity among manufacturers for cable production.

The versatility of PVC allows it to be formulated with various additives to enhance specific characteristics, such as UV resistance or improved mechanical strength, further broadening its usability in various electrical and telecommunications applications. This adaptability aligns well with the demands of contemporary wiring methods and installations, establishing PVC as the preferred material for cable jackets in the industry.
