Nufalt SR
Nufalt SR is a closed Heat-Shrinking tube, composed of a highly resistant modified polyethylene film and highly adhesive bituminous sealant for protection against corrosion. After shrinking the NUFALT SR sleeves provide long protection against corrosion in a wet environment as well as very good mechanical resistance.
Main advantages :
- No primer required
- Excellent tightness thanks to the interior sealant
- Excellent resistance to weather conditions
- High medical resistance
- High resistance to mildew and bacteria
- Clean and ease application
Application
Corrosion portection for welded joints, steel or cast-iron pipes pre-coated in the workshop
Protection and reinforcement of junctions between different materials and different diameters
Tightness of pipe junctions, for instance : rainwater drainpipe in PVC, zinc, etc
Distribution of leaks on pipe, up to 5 bars.
