Before we understand polyphenolic thermosetting insulation materials, we must first understand what kind of material it is made of. This product is mainly made of phenolic foam material, so we must first understand the characteristics of polyphenolic foam.
1, high flame retardant, low smoke. The oxygen index can reach 56%, the smoke density is less than 5. 1200 °C does not burn, and only carbonizes without dripping in case of fire.
2. Good insulation and low thermal conductivity. The phenolic foam material is composed of "closed small bubbles" and can be well resisted.
The phenomenon of thermal convection formed by the breaking temperature. Its thermal conductivity is 0.02 ~ 0.03w / mk, to achieve energy saving purposes.
3. Weather resistance is stable and heat resistance is high. The phenolic thermal insulation foaming material has a use temperature of -60 ° C to 150 ° C, stable size, no water absorption, anti-aging and long service life.
4, no fluorine foam, non-toxic and tasteless, is green building materials. The foaming process does not use CFCs, and the ratio is reasonable.
The reaction is complete, and the formed compound has no residual poison, no odor, acid and alkali resistance, and good resistance to acidic alkali.
Material application
Polyphenolic thermosetting insulation board and tube shell are widely used in thermal insulation engineering of tunnel insulation, civil, industrial, petroleum, chemical, defense, military, ship hull, train car, cold storage and other fields with their unique flame retardant properties.
