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
