PPR-FR-PPR
Pipes
Fire-Retardant PPR Composite
Piping Systems for High-Safety
Installations
Edoburg’s PPR-FR-PPR pipes are multilayer composite pipes designed for fire-prone, heat-intensive, or safety-critical building environments. Constructed with a central Fire-Retardant (FR) layer bonded between two outer layers of polypropylene random copolymer (PPR), this system enhances both flame resistance and structural integrity — without compromising on flexibility or chemical durability.
Compliant with DIN 8077 / 8078 for dimensional and performance benchmarks, these pipes are suitable for institutional, industrial, and high-rise infrastructure where fire containment and material stability are paramount.
