Wire and Cable Jacketing Materials Comparison

Many specifiers of technical products look for more detailed information on the products they select for their most critical applications. In an effort to help provide data to make more informed decisions, Anixter has amassed common values of important material characteristics and summarized them in the following table. These values are approximate and nominal and are only intended to be representative. Values vary from manufacturer to manufacturer and among product grades. These values are predominantly drawn from industrial tray cable products.
