FR TPU with good abrasion resistance
Thermoplastic polyurethanes and thermoplastic urethane (TPU) are generally used as a secondary insulating material for wire and cable applications, and in special cases it is used as a primary insulator. All materials listed are processable by extrusion and injection molding. For example, TPU thermoplastic polyurethane is used as a jacketing material for above-ground mining cables due to its high abrasion resistance and as the primary insulator for flat cables in the automotive industry.
When selecting jacketing material for a cable, criteria to be considered are mechanical, environmental and chemical stability of the polymer, thermal and electrical properties as well as design requirements of the specific application.
