Polyurethane composite board characteristics
2. Flame retardant; Oxygen index & ge; 40, belongs to the flame retardant materials.
3. Heat resistant; Can be in - Use between 196 ℃ ~ 150 ℃, short time heat 200 ℃.
4. Low smoke low toxic; Down there is a small amount of CO and no other toxic gases. The five great smoky density. 74% 0%, and the most great smoky polyurethane foam density.
5. Corrosion resistant anti-aging; Phenolic foam can almost all inorganic acid, organic acid, organic solvent and the erosion of salt. Compared with other thermal insulation materials, a longer service life.
6. Flame penetration resistance; Under the effect of flame directly with carbon, without dripping, curly, no melting phenomenon, after the flame, basic retain foam, just surface formation layer & other The graphite foam & throughout; Layer, the effective protection layer of foam structure, its resistance to fire through time can be more than 1 h
7. Green environmental protection; Products non-toxic mould, do not use fluorine chlorine hydrocarbons foaming, does not destroy the ozone layer. http://www。 juanzhibwb。 com
