Kapton®/Teflon® insulating tube, non-shrinking class, H (180 °C)

€0,00

Wound Insulation Tubes for applications in temperature class H.

Inner diameter from 1.6 mm.
Wall thicknesses from 0.075
For applications in temperature class H up to180 °C.
The insulating pipes are also available with color coding for differentiation.
The material is UL

Wound Insulation Tubes are made of Kapton® and coated with FEP for use in the most demanding applications. It is used where high dielectric strength, mechanical strength and moisture resistance are required despite low wall thicknesses. It is suitable for applications with the harshest environmental conditions and operating temperatures of up to 200 °C. The structure with adhesive-free welding guarantees that only FEP and polyimide are contained in the product.
