Nomex®/Mylar® insulating pipes, shrinkable, class F (155 °C)

Nomex®/Mylar® insulating pipes, shrinkable, class F (155 °C)

€0,00

 

The Mylar®/Nomex® insulating tube insulates and secures electrical connections in electric motors and other applications. Due to its high dielectric strength and impact resistance, this shrinkable insulating tube can also be used in demanding applications at short-term temperatures of up to 160 °C. Please call us for more information.
