PUR-Impregnated Fiberglass Insulating Sleeving: Protection up to 160°C
The PUR-impregnated fiberglass insulating sleeving offers excellent protection for electrically, thermally, and mechanically stressed components. The combination of alkali-free E-glass and high-quality polyurethane impregnation varnish ensures high dielectric strength and flexibility, even after intense thermal stress.
Customer Benefits: Maximum Safety in Critical Applications
This insulating sleeving is the ideal solution for electric motor and transformer construction, as well as machine, plant, and apparatus construction. Your key advantages:
- Thermal Resistance: No cracking or loss of flexibility after several hours of heat treatment at 160°C – for durability under continuous load.
- High Dielectric Strength: With a voltage of 4000 V, the sleeving provides reliable electrical insulation.
- Chemical Resistance: Good resistance to benzene and oils, increasing application safety in contaminated environments.
- Robust Construction: The alkali-free E-glass fabric ensures high mechanical stability and durability.
Technical Data & Construction
The sleeving is impregnated in several precise steps to guarantee the optimal connection between the fabric and the insulation material.
