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℃).
产品优势：
1、热固性材料、阻燃等级高，达到国家GB8264标准之B1级；
2、导热系数低、绝热效果极优、使用温度范围: -196℃～+150℃；
3、具有无氟、环保、防腐、防霉变等特点
4、机械强度高、尺寸稳定性佳、经久耐用；
5、数控切割，可满足不同厚度的保冷要求
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.
