聚异氰脲酸酯泡沫(PIR-Polyisocyanurate)，亦称聚异三聚氰酸酯或深冷三聚酯，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-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℃).
