聚異氰脲酸酯(PIR)

DZGR-PUR-500
Rigid Polyurethane Foam
聚氨酯硬質泡沫塑料(PUR)

聚氨酯硬質泡沫塑料是用聚醚或聚酯與多異氰酸酯為主要原料,再加阻燃劑、穩定劑和發泡劑等,經混合、攪拌產生化學反應而形成發泡體的一體新型的低溫隔熱材料。孔腔的閉孔率高,吸水性小。

由于其氣孔為低導熱系數的發泡劑氣體,有一定的自熄性、常用來做保冷和低溫范圍的保溫。它具有導熱系數小、強度高、質輕、隔音、防震、絕緣、漂浮性強、化學性能穩定、施工方便等優點,廣泛應用于石油、化工、乙烯、冷庫、食品儲藏及家庭用具電冰箱和建筑工業中隔墻、壁板等行業中使用。應用時,可以由預制廠制成板狀或管殼狀等制品,也可以現場噴涂或灌注發泡。

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.
