Polyurethane foam (PUR) is a closed cell thermoset polymer. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or poly-isocyanate with a polyol. Polyurethane foam insulation is available in closed-cell and open-cell formulas.Pipe Insulation with PolyurethaneApplication fields of PU for pipe insulation District Heating / District Cooling Flexible pipe Fluid: Water Outer jacket: Polyethylene Carrier Pipe: Steel, copper, PEX Temperature: 3 °C - 150 °C Semi-flexible rigid foam based on PUR Moulded density: 55 - 70 kg/m³ High requirements for the whole systemIntek® PFI-1120 High Temperature Foam InsulationIntek PFI-1120 High Temperature Foam Insulation is used in commercial, industrial and defense markets as a lightweight, non-flammable, thermal and acoustic insulation and is suitable for when high temperature resistance is required. It is formaldehyde-free and demonstrates excellent long term stability under humid conditions and after temperature cycling.
Polyurethane foam insulation is available in closed-cell and open-cell formulas. With closed-cell foam, the high-density cells are closed and filled with a gas that helps the foam expand to fill the spaces around it. Open-cell foam cells are not as dense and are filled with air, which gives the insulation a spongy texture and a lower R-value.Insulation - Plastics & RubberPU insulation materials are based on ridgid foam system with a close cell content of > 90%. Its material density usually range from as low as 30 kg/m3 to 100 kg/m3. In some cases high density systems of up to 500 kg/m3 are required.
