Commercial PP-RCT

PP-RCT (polypropylene co-polymer – random crystallinity temperature) material is the latest PP resin development in the polypropylene family and has a wide range of benefits for commercial plumbing systems. It has a more complex crystalline structure that provides greater pressure capabilities at higher temperatures than conventional PP materials, making it suitable for higher temperature applications such as boiler and hot water systems. With more than a 50 percent improvement in long-term (50 years) strength over PP-R, PP-RCT piping systems allow designers to choose thinner walled, lighter pipes and possibly smaller diameter pipes, while maintaining the necessary system pressure ratings and providing higher flow rates and greater efficiencies and cost savings.

This material also allows larger support spacing, making it easier to replace metal piping without re-engineering a piping system. PP-RCT can also be extruded in a multilayer pipe with fiber core middle layer which reduces the impact of thermal expansion on the piping system. Our new PP-RCT piping systems fall in line with LEED’s guidelines and are considered environmentally friendly, as well as energy efficient.
