What is Polyurethane / PUR?

Polyurethane, also referred to as PUR, PU, and TPU, is a thermoplastic material used in wire and cable construction. Polyurethane is often utilized as a jacketing material for harsh environments as it has excellent mechanical properties and chemical resistance. It is not typically used for insulation as it has poor electrical properties. Polyurethane is UV resistant, water resistant and has a wide temperature range, making it a popular choice for outdoor applications. Polyurethane is a highly flexible compound and is typically found as a jacketing material in continuous flex applications. PUR is used as a jacketing material for retractile cords as it displays outstanding memory qualities. There are a wide variety of polyurethane compounds available, and many are halogen-free. A drawback of polyurethane is that it is highly flammable; however, there are flame-retardant versions available.
