Phenolic insulation board compared with other thermal insulation material _ phenolic insulation board, phenolic board manufacturer

Phenolic insulation board is a new type of green environmental protection material, it is made of phenolic resin in flame retardant and smoke suppression agent, foaming agent, curing agent and other additives made of closed-cell rigid foam. - in its use for a long time 250 ℃ ~ 150 ℃, encounter fire non-combustible, under the environment of high temperature does not drop, not soften surface carbonization. Phenolic insulation board coefficient of thermal conductivity is only 0. 023W/m. K, almost with polyurethane, heat preservation performance is very good. It is the most prominent feature of flame retardant, low smoke, high temperature resistance of indeterminacy. It can be on-site pouring foam, can be molded, can also be mechanical processing, can be made into sheet, tube shell and all kinds of different products. It overcomes the original type foam thermal insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam thermal insulation material is qualitative light, construction is convenient wait for a characteristic. Phenolic plate rich raw material sources, low price and simple production and processing, product use is broad. It is suitable for large cold storage, storage tank, ships and various kinds of thermal insulation pipe and construction. When used for fire protection requires strict factories and machinery and equipment, more can highlight its flame retardant, low smoke, resistance to high temperature of different characteristics. Such as ships, ships, trains, vehicles of heat preservation and paper, chemical, pharmaceutical, etc.

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.

above phenolic insulation board is the sale of our products, if the new and old customers are interested in our products phenolic insulation board, please inquire.
