K‑FLEX PU Sheet is a rigid polyurethane (PUR) insulation board engineered for thermal protection of surfaces, tanks, vessels and fabricated shapes. Its closed‑cell PUR structure provides excellent energy efficiency while maintaining high dimensional stability for industrial and HVAC applications.
Key Features & Benefits
- Closed‑cell rigid PUR foam delivers consistent insulation performance.
- Low thermal conductivity: λ40°C ≈ 0.0349 W/m·K for reliable heat control.
- Temperature suitability up to +110°C for hot and cold service applications.
- Available in practical board formats including 1×1 m and 2×0.5 m.
- Rigid and lightweight for easy fabrication into custom components.
Applications
- Insulation of tanks, vessels and large diameter piping
- OEM equipment housings and mechanical enclosures
- Cold rooms, refrigerated surfaces and panels
- General industrial thermal insulation where rigid PUR is required
