Polyisocyanurate
聚異氰脲酸酯(PIR)

聚異氰脲酸脂(PIR)是由異氰酸鹽經觸媒作用與聚醚發生反應制成發泡材料,其物理與防火性能比一般矛氦酯泡沫塑料更為優異。 是一種理想的有機低溫隔熱材料。具有導熱系數小。阻燃性能強、輕質防震、適應性強。廣泛于LNG、煉油廠、化工廠、乙烯、化肥、冷庫及建筑業保溫隔熱。

Polyisocyanurate (PIR) is a foamed material which is obtaired after isocyanate reacts with polyether through accelerant. The physical and fire resistance are better than ordinary polyurethane foamed plastics. It is an ineal organic low-temperature heat-insulating material, with low heat concluctivity coefficiert, strong flame resistance, light weight, shock resistance and strong adaptability, widely used for the insulation at LNG, refineries, chemical industries, ethylene, chemical fertillizer, refrigerating ware house and construction industries.
