High Density PIR / High Density PUF

High Density PIR/High Density PUF is foaming polymer have the features of plastic, rubber and cork wood, produced through high speed stirring with the main raw material of isocyanate and polyether, added with foaming agent, contacting agent and flame retardant. Finished product has three-dimensional honeycomb structure, composed by thousands of tiny uniform hermetically sealed cells. It have low thermal conductivity, high compressive strength, low water adsorption,  anti-hydrolyses, non-flammable, molding exactitude, which wood products can not compare with, it's a new ideal material for cryogenic pipe line and equipment's supports, bearing part and bracket.
