For decades, polypropylene random copolymer (PP-R) has been applied worldwide successfully for hot and cold water applications. Material properties such as resistance to internal pressure, flexibility and impact have made PP-R the material of choice for a safe and reliable long-lasting installations like hot and cold water distribution, underfloor heating, radiator connections or wall cooling and heating systems.

Benefits of PP-R

• 50 years lifetime according to tests performed under ISO 15874
• No limitations to the pH value of water
• No contact corrosion when exposed to iron particles
• Taste and odour neutral
• Bacteriologically neutral
• Fast and easy installation
• Entire plastic systems available
• Good chemical resistance
• Low tendency to incrustations

PP-RCT is the next generation of PP-R raw material. PP-RCT is an abbreviation for Polypropylene Random Copolymer with modified crystalline structure and enhanced temperature performance. The special fine and homogeneous crystal structure of the PP-RCT material improves the mechanical characteristics of the material.

Benefits of PP-RCT

• Improved stress resistance at elevated temperatures. PP-RCT pipe systems can be operated at higher operating pressures
• The improved long-term strength of the PP-RCT material leads to a more economic set of dimensions of the pipe system. Where possible, it enables designers to select thinner wall pipes with an increased flow capacity or smaller diameter pipes. Lighter pipe systems are easier and quicker to install
• The substantially lower material usage provides an additional contribution to the conservation of resources supporting a sustainable environment
