PIR (Polyisocyanurate) Insulation Board & Pipe Section
Closed-cell polyisocyanurate foam for low-temperature pipework, ducts and tanks — the lowest thermal conductivity in the insulation range, with high closed-cell content and negligible water uptake.
Technical parameters
| Core | Polyisocyanurate (PIR) foam, CFC/HCFC-free, ODP zero |
|---|---|
| Density | 40 – 50 kg/m³ (45 ± 5 typical) |
| Thermal conductivity | ≤ 0.023 W/m·K at 23 °C; ≤ 0.022 W/m·K at − 50 °C |
| Closed cell content | ≥ 90 % |
| Service temperature | − 196 °C to + 120 °C |
| Compressive strength | ≥ 200 kPa at 10 % deformation |
| Forms | Board, preformed pipe section, poured-in-place |
| Reaction to fire | Fire-retardant grade; A-class build-ups with facing on request |
Applications
- Low-temperature chilled-water and refrigerant pipework
- Cryogenic pipe and valve insulation
