Product information on C2C product Innovation institute

Flexalen 600 is a flexible, pre-insulated pipe system for heating, cooling, and potable water applications. It is made of a polybutene carrier pipe that is enclosed by polyethylene foam with a corrugated HDPE outer casing, between which a homogeneous water-tight bond is secured. All Flexalen materials are designed to be recyclable. The polyolefin material is designed to provide insulation while also providing homogeneous welding connections through electrofusion, polyfusion, and butt welding technology. Flexalen pipe systems are designed to be corrosion-free and pressure- and temperature-resistant. Flexalen 600 is available with single or twin carrier pipes, and with the option of an oxygen barrier around the Polybutene pipe. Insulation is also available in various thicknesses.
