A polymer is a material of high molecular weight formed by the chemical union of many monomers, the basis of the plastics and rubbers used in cable.
A polymer is a large molecule of high molecular weight formed when many small molecules called monomers chemically link together into long chains. This process, called polymerization, produces the plastics, rubbers, and resins that make up cable insulations, jackets, and other components. The identity of the monomers and the structure of the chains determine the polymer's properties.
Because polymers can be engineered with a wide range of electrical, thermal, and mechanical characteristics, they are the foundation of modern insulation and jacketing. Materials such as polyethylene, PVC, and fluoropolymers are all polymers chosen for the specific properties their chemistry provides.
In commercial and industrial cable, the polymers used for insulation and jackets determine how a cable performs and endures. Understanding the polymer basis of these materials underlies the differences among cable constructions.

Recognizing how polymer chemistry shapes material properties helps illustrate the basis for the differences among cable insulations and jackets, and ultimately for dependable cable performance.
This makes polymers the foundation of cable insulation and jacketing, with the chemistry of each material determining how a cable performs and endures in its application.
At Windy City Wire, an understanding of material fundamentals, including polymers, supports the selection of low-voltage cable with appropriate insulation and jackets. Recognizing how polymer chemistry shapes material properties helps illustrate the basis for dependable cable performance.
