聚异氰脲酸酯(PIR)

DZGR-PUR-500
Rigid Polyurethane Foam
聚氨酯硬质泡沫塑料(PUR)

聚氨酯硬质泡沫塑料是用聚醚或聚酯与多异氰酸酯为主要原料,再加阻燃剂、稳定剂和发泡剂等,经混合、搅拌产生化学反应而形成发泡体的一体新型的低温隔热材料。孔腔的闭孔率高,吸水性小。

由于其气孔为低导热系数的发泡剂气体,有一定的自熄性、常用来做保冷和低温范围的保温。它具有导热系数小、强度高、质轻、隔音、防震、绝缘、漂浮性强、化学性能稳定、施工方便等优点,广泛应用于石油、化工、乙烯、冷库、食品储藏及家庭用具电冰箱和建筑工业中隔墙、壁板等行业中使用。应用时,可以由预制厂制成板状或管壳状等制品,也可以现场喷涂或灌注发泡。

Rigid polyurethane foam (RPF) is a foamed insulating material used under low-temperature circumstances. RPF is obtained by using either polyether or polyester and polyisocyanate as the main raw material added with flame-retarding agent, stabilizing agent and foaming agent, etc., which are mixed and stirred for chemical reaction, RPF is featured in the high closing rate of the pore cavities and small moisture absorption.

Sicne the cavities are full of foaming agent gas with low heat conductivity, the material extinguishes fire automatically, normally used for refrigerating and insulating at low temerapture range. It is featured in low heat conductivity, high strength, light weight, sound baffling, shock resistance, strong drifting, stable chemical performance and convienient engineering. As aresult, it is widely used for the walls at petroleum, chemical industries, ethylene, refrigerating warehouse, food strage, home refrigerators and convieniert engireering. As aresult, it is widely used for the walls at petroleum, chemical industries, ethylene, refrigerating warehouse, food storage, home refrigerators and construction industries. When using it, it can be made into plarks or tubes. or site coated or foam filled.
