Product Description
PIR Polyisocyanurate Foam Pipe Insulation for Low Temperature Applications
PIR (Polyisocyanurate) foam, also known as polyisocyanuric acid ester foam, is produced through the reaction of isocyanate with polyether under catalysis. This advanced insulation material offers superior physical and fireproof properties compared to standard polyurethane, making it an ideal organic thermal insulation solution for low-temperature environments.
Key Advantages
- Exceptionally low thermal conductivity for optimal insulation performance
- Lightweight construction with excellent shock resistance
- Superior fire resistance properties
- High adaptability for various industrial applications
- Widely used in LNG, ethylene, and cold storage industries
