Phenolic insulation board compared with other thermal insulation material _ phenolic insulation board, phenolic board manufacturer
phenolic insulation board all kinds of insulation material performance comparison:
1, the defect of polyurethane (pu) : meet fire easy burning, easy to produce poison, harm human health;
2, the defects of polystyrene: meet the fire burning, with long will shrink, heat preservation performance is poor;
3, rock wool, glass wool defects: bad for the environment, the breeding ground for bacteria, bibulous rate is high, poor heat insulation effect, strength is poor, short service life;
4, phenolic advantages: non-combustible, no gas and smoke after burning, low thermal conductivity thermal insulation effect is good, sound insulation, weather is good, life can be up to 30 years;
5, have closed pore structure are uniform, low thermal conductivity, good thermal insulation performance, polyurethane and its better than polystyrene foam;
6, suitable temperature range is big, can be in - in the short term With under 200 ℃ ~ 200 ℃, and can use for a long time under the 140 ℃ ~ 160 ℃, is better than that of polystyrene foam ( 80℃) And polyurethane foam ( 110℃) ;
7, phenol molecules contain only carbon, hydrogen, oxygen, by pyrolysis, in addition to produce a small amount of CO gas, won't produce other toxic gases, the most great smoky density of 5. 0%. 25 mm thick phenolic foam board after 1500 ℃ flame spray after 10 min, only slightly carbonization is don't wear surface, neither fire nor send out smoke and poisonous gas;
8, phenolic foam, except may be strong alkali corrosion resistance can almost all inorganic acid, organic acid, organic solvent. Long-term exposure to sunlight, no obvious aging phenomenon, thus has good aging resistance;
9, phenolic foam cost is low, only about two-thirds of the polyurethane foam.
