- 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
