1.More than 35 years Service life 2.Fireproofing, satety, non-toxic, easy installation and maintenance 3.sound insulation
Guangzhou Wide Phenolic Foam is new generation enviromental insulation material, when it is burnt, it has no smoke, it gives out non-toxic matter, the material is fire-resistant, insulated water and moister resistant anticorrosion, anti-aging, sound insulation and energy-saving, meanwhile the contractility is low and not brittle, expecially the outstanding fire-resistance performance show the broad applying goreground, and it will replace the old insulation material. Phenolic foam is the best material for fire building performance in polymers.
We introduce a complete set of entirely-auto extrusion molding phenolic foam composite constant product line, this is the first introduced Extrusion Molding Phenolic Foam composite constant product line in China, it bridge the gap between China and the world, and the product quality and enviromental disposal both keep ahead in the world.
Characteristic
1. Insulation and energy-saving
Phenolic foam has low thermal conductivity, it can meet the requirements of anti-condensation, decreasing cold-loss for air conditioner ventilation duct, the energy saving effect is obvious.
2.Excellent fireproofing, safety, non-toxic, long working life
Phenolic foam is the best fireproofiing material among polymers, is the most popular used around the world now. it is smelless and non-toxic, gives off low smoke. The embossed foil makes long using life.
3.Light and steady, sharply saving resource
The duct weight is only 1.4Kg/m3, hardness and strength are good enough, and it can endure high wind pressure, it can shrply reduce the using steels quantity.
4.Good appearance and cleanness
the surface of the duct is composite aluminum foil with anticorrosion epoxy protection, the insulation is enviroment phenolic foam which is nontoxic, no dust. Thus a perfect enviroment comes into being.
5. Working and installation noise is low, make the enviroment more comfortable
Phenolic foam itself is excellent sound insulation amterial, the echo and vibration will be absorbed by the materiali. And no beating is needed, so the installation noise is avoided, the materiali is expecially suitable for the situation that has restrict requirement for installation noise.
6. Making, installation is easy and the maintenance is simply.
The material is easy to be cut, bent and installed, the maintenance is also simple.
Connection profile
It contains interior aluminum, exterior aluminum and phonelic foam board.
1.Aluminum Interior of the duct
Antibacterial Epoxy coated aluminum will make the material anticorrisive, protect the germ,s and prevent the air pollution within the duct.
2.Phonelic Foam Board
Enviromental Phenolic Foam, no CFC, no ordor, non-toxic and fireproofing, low smoke.
3.Aluminum Exterior of the Duct
Embossed structure creates sturdy exterior, which will protect it from any outside impact. It will also have corrosion resistant feature from Epoxy coating. Epoxy coatinig will enable to creat vairous colors.
Test report and certificate
Wide Pre-insulated phenolic foam duct sheet has been undergone a series of tests in abroad laboratories by using hi-tech instruments. It is indentified and certified with class1 for fire-resistance according to BS476 PART6&7.
