High Density PIR / High Density PUF

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. Dehe manufacture High Density PIR / High Density PUF, foam glass, grill stone, thermal insulation material with high quality. Product Advantage 1.Low thermal conductivity; 2.High compressive strength and high flexural strength; 3.High closed cell rate, low water absorption; 4.Excellent flame retardant; 5.Strong anti-corrosion, vermin proof; 6.Can be perfabricated in molds, NC mechanical cutting, meet various thermal insulation designed thickness
