NCflex & NCgel
Flexible, Re-enterable and Moisture-Resistant Protection
The NCflex and NCgel product family is developed for electrical insulation applications where serviceability, re-entry and moisture / water protection are required. Polybutadiene-based NCflex PBD W-25 and NCflex PBD W-30 systems, together with transparent silicone-based NCgel, provide technical solutions for junction boxes, cable connections, battery packs and field-type insulation applications.

Why are gel or elastic electrical insulation systems needed?
In some electrical connections, a rigid potting compound is not enough. If maintenance, testing, measurement, re-entry, removal or moisture protection is required, the insulation system must be flexible, serviceable and suitable for the real application conditions.
Maintenance and re-entry
A removable structure provides a major advantage in applications where the connection may need to be opened, inspected or replaced later.
Moisture and water protection
Hydrophobic systems provide a safer protection approach against moisture and water around the connection area.
Flexibility
In areas exposed to vibration, thermal expansion or movement, a flexible system can be more tolerant than rigid potting materials.
Application-based selection
Not every application requires the same resin. Rigid PU, elastic PU, PBD-based systems or silicone gel should be selected according to application conditions.
Where do conventional polyurethane resins struggle?
Standard polyurethane resins may be sensitive to atmospheric moisture while they are still in liquid form. In humid environments, unwanted reactions may occur during casting; this can increase the risk of foaming, bubbles or internal voids.
In addition, many conventional PU systems cure into a relatively rigid structure. This can make removal and service operations difficult in applications where the connection needs to be accessed again later.
Why is NCflex PBD different?
- Polybutadiene-based hydrophobic structure
- High resistance against moisture
- Targeted very low water absorption
- Flexible and removable cured structure
- Can be separated manually without aggressive mechanical tools
- Suitable for connections requiring maintenance and re-entry
Difference between NCflex PBD and silicone gel systems
Silicone gels offer advantages such as high temperature resistance and transparency. However, not every application requires +200°C temperature resistance. In applications where extreme temperature resistance is not required, NCflex PBD systems can be evaluated as a more economical and practical alternative.
Select the right gel or elastic system for your application
NCflex and NCgel products respond to different technical requirements such as removability, probe measurement, transparent inspection, maintenance access and field application conditions.
