RAKtherm pipes and fittings are made with a material called polypropylene, which is used extensively in food and medical industries because of its safe properties. A random copolymer grade of polypropylene called PP-R 80 was especially developed for engineering applications with certain stringent requirements. PP-R 80 is characterized by excellent physical and chemical properties even at elevated temperatures. Compression strength, elasticity, corrosion, chemical and heat resistance are just some of these properties. RAKtherm PP-R 80 system has proven its high resilience even at the most extreme conditions. These factors and more, make RAKtherm PP-R 80 the ideal material for the delivery of potable hot and cold water in your home, office, or factory.
