PIR聚异氰脲酸酯/聚异三聚氰酸酯泡沫PolyisocyanurateFoam

     

    聚异氰脲酸酯/聚异三聚氰酸酯泡沫(PIR-Polyisocyanurate)，亦称深冷三聚酯泡沫，是新型专业深冷绝热材料，物理性能与防火性比普通聚氨酯更为优异，尤其体现在绝热效果和阻燃性能上。其制品广泛应用于从-196℃～+150℃范围内的各种设备、管线的保冷，能为超低温的液氮(LN(0)，-196℃)、液化天然气（LNG，-162℃）、液态乙烯(LEG,-104℃)、液化石油气（LPG，-48℃等介质的提供高效稳定的绝热效果。

     PIR-Polyisocyanuratefoam isa new professional cryogenic insulationmaterial. It’s better than common polyurethane foamboth in physical properties and fireproofperformance,especially oncold insulation effects and fire retarding performance. PIR canbe used in adiabatic demand of pipelines and equipment within-196℃～+150℃, it also provides the best efficient and stable cold insulation effects for LiquefiedNitrogen (LN(0),-196℃),LiquefiedNaturalGas(LNG,-162℃),LiquefiedEthylene (LEG,-103.9℃).
