PIR-Polyisocyanurate
PIR-Polyisocyanurate
PIR-Polyisocyanurate foam is a new professional cryogenic insulation material. It’s better than common polyurethane foam both in physical properties and fireproof performance, especially on cold insulation effects and fire retarding performance. PIR can be used in adiabatic demand of pipelines and equipment within -196℃～+150℃, it also provides the best efficient and stable cold insulation effects for Liquefied Nitrogen (LN(0),-196℃), Liquefied Natural Gas (LNG, -162℃), Liquefied Ethylene (LEG,-103.9℃).
Products advantages:
1. Thermosetting material with combustion retarding, meeting B1 Fireproof Grade of the national standard GB8264；
2. Low thermal conductivity, excellent cold insulation effects with temperature ranging from -196℃ to +150℃.
3. It features fluorin-free, environment-friendly, anti-corrosive, anti-mold and etc.
4. High mechanical strength, dimensional stability and durable life.
5. NC Mechanical cutting in advance, various thicknesses for cold insulation requirements.
