Why PUR Is Used for Mobile Cable Applications
July 2026
An introduction to the role of polyurethane outer sheaths in flexible and continuously moving cable systems.
A sheath for demanding movement
PUR is frequently considered when a cable must combine flexibility with resistance to abrasion and mechanical wear. The final compound should always be selected for the installation conditions.
Environmental factors matter
Oil exposure, outdoor use, low temperature, water contact and cleaning agents can influence material selection. No single sheath is ideal for every application.
Evaluate the complete cable
Sheath material is only one part of a mobile cable. Conductor stranding, core arrangement, shielding, reinforcement and manufacturing quality also affect service performance.
Editorial note: Final product selection should be confirmed using the actual electrical, mechanical and environmental requirements of the application.
