PUF (Polyurethane Foam) slabs and pipe sections are high-efficiency, rigid, closed-cell insulation materials used to prevent heat transfer in cold storage, HVAC, pharmaceutical, and industrial applications. They offer superior thermal resistance, low conductivity (K=0.14 K Cal/mhroC), and, with a standard density of 36–40 kg/m3, provide durable, moisture-resistant insulation for temperatures ranging from -180°C to 110°C.
