What are UNT rigid phenolic foam pipe insulation?
Jul 09, 2018

Phenolic insulation is phenolic resin and flame retardant, smokproof agent, curing agent, foaming agent, and other additives and other substances, by scientific formula made of rigid foam with closed pores.The most prominent advantages are fire protection and insulation.


Application field of phenolic pipe insulation

With polystyrene foam and polyurethane foam are flammable, not high temperature resistant, in some developed countries use is limited by the fire department, strict in fire protection, government departments have clear stipulation can only use phenolic insulation board.

Therefore, phenolic foam materials are more suitable for high performance materials used in demanding environmental conditions and have good development prospects.Such as steel structure plant, large industrial plant, activity room, cold storage, clean workshop, building layering, temporary housing, gymnasium, supermarketand other buildings that need fire protection and heat preservation requirements.

 

Advantages of phenolic foam insulation

1. Excellent fire protection performance: organic insulation materials such as polyurethane and polybenzene will produce smoke and highly toxic smoke after burning, which is easy to cause death of people, and also increases the difficulty of fire fighting.And phenolic non-combustible insulation board in the fire, burning performance up to A level, the highest temperature is 180 ℃ (250 ℃) allow instantaneous, 100 mm thick phenolic foam flame resistance can be more than 1 hour and not get through.Under the direct action of the flame, there is no carbon deposition, no dropping, no curling and no melting. After the flame burns, a layer of "graphite foam" is formed on the surface to effectively protect the foam structure within the layer.

2. Excellent adiabatic performance: low thermal conductivity (< 0.025w /m·K, more than twice of polystyrene, similar to polyurethane), good material for heat preservation and heat insulation;

3. Anti-corrosion and anti-aging: able to resist almost all inorganic acids, organic acids and organic solvents.Long-term exposure to sunlight, no obvious aging phenomenon, therefore has good aging resistance;

4, small density, light weight, the density of phenolic insulation board for below 100 ㎏ / m3, can achieve about 50 ㎏ / m3.It can reduce the self-weight of the building, reduce the load of the building and reduce the construction cost.

5. Sound absorption performance: phenolic insulation board has excellent sound absorption performance, and the foam structure with closed hole is more conducive to sound resistance;

6. Environmental protection: rock wool and glass cotton are harmful to the environment and people. When burning and heating, polyurethane and polystyrene will decompose hydrogen cyanide, carbon monoxide and other highly toxic gases.And phenolic heat preservation board USES non-fluorine foaming technology, no fiber, in line with national and international environmental requirements.

 

Extensibility of rigid phenolic foam pipe insulation

Phenolic insulation board is a new generation of thermal insulation, fire prevention, sound insulation material, and foam polystyrene, polyurethane, rubber and plastic materials such as compared to the biggest characteristic of good heat resistance, low temperature shrinkage of small, has a unique flame retardant and dimensional stability, not burning, not melt under the high temperature of 200 ℃, no contraction, no poison, no smoke, no drip, just surface with a carbonized layer.It has strong effects of environmental protection and energy saving., comprehensive performance is superior to the traditional duct materials, fill the domestic blank of new advanced energy-saving insulation materials, products and production technology level, the world's leading especially suitable for senior hotels, phenolic foam within 160 ℃ ~ 190 ℃ can be used.Mainly used in hotels, large buildings such as central air-conditioning, hot and cold water system of heat preservation, suitable for oil, gas, heat insulation, chemical piping, equipment can also be applied to industrial wall heat insulation, the fire of inflammable material warehouse, fireproof heat insulation wall body.Office building, shopping mall, hospital, pharmaceutical factory, high cleaning workshop, subway and other places.With the general air - conditioning insulation air duct incomparable unique advantages.It has been widely used in Europe, America, Japan and other developed countries.

Phenolic heat preservation board is a new type of refractory, fireproof and low-smoke insulation material, and its thermal conductivity is only about 0.023w /m·k. The most prominent features are refractory, low-smoke and anti-high temperature deviation.It has the characteristics of light weight and convenient construction.Phenolic insulation board wide range of USES, it is suitable for industrial buildings, civil construction, public buildings, overlay houses, warehousing logistics, public transportation, municipal pipeline, petrochemical and industrial equipment, and other fields.
