By introducing an automated continuous large production line of fireproof modified phenolic insulation board,applying modified phenolic foam and conducting technical improvement,
The board passed the tests by China Building Material Test Center on Jul. 20, 2011, complying with the national requirements with regard to burning performance and other indicators: its burning performance meets the requirements of grade-A composite (laminated) material specified in GB8624-1997 Standard;its volume density, compressive strength, flexural strength, compression creep, size stability, coefficient of heat conductivity, coefficient of moisture permeability and volume water absorption all conform to the requirements of grade-A type II product specified in GB/T 20974-2007 Standard.
The board is applicable to:
(1)Building walls, roof insulation and the insulation layer of composite boards;
(2)The fire barrier zone of the insulation system for traditional EPS/XPS/PU exterior walls;
(3)Fireproof insulation within curtain walls, insulation for fireproof doors and fireproof insulation in low-temperature or high-temperature conditions.
- Q:Is the polyurethane sandwich panel and foam board flame retardant?
- On the market, the polyurethane foam flame retardant grade B1, B2, B3 three grades. Because of the cost, sandwich board with the majority of polyurethane material is B3 level, a small amount of B2 level, there are a small amount of special requirements B1 level. B1 level for the 'flame'; B2 level for the 'combustible'; B3 level for the 'flammable'. B1 grade oxygen index requirements of more than 30%; B2 level requirements of more than 26%, 26% of the following collectively referred to as B3 level. You said the flame retardant, it should be self-extinguishing from the fire. B2, B1 from the heat certainly no problem. A little better B3 (oxygen index of about 25%) can also be self-extinguishing, but more than B2 self-extinguishing time more than a few seconds. General oxygen index of less than 24%, it is difficult to self-extinguishing from the fire, will always burn, the greater the greater the burning. The The Oxygen Index: The concentration of oxygen required to stabilize the combustion in the oxygen and nitrogen gas mixture under the specified shape of the foam, the specified source of fire and the size of the flame. - For example, the better the flame retardant properties of the foam, the higher the concentration of oxygen needed to ignite the foam, the higher the oxygen index of the bubble
- Q:Is the foam sandwich plate formaldehyde?
- Use to enjoy the formaldehyde detector under the test to know whether it contains formaldehyde, and large screen real-time display, triple alarm preset function, Portable compact hand.
- Q:With a foam sandwich board made a 72 flat house, the cheapest how much money

- Swallowtail screws (also known as drilling screws) is a color plate dedicated screws, thousands of square meters of large factories are fixed with how it will be unstable, light steel keel is absolutely not work.
- Q:What is the polyurethane fireproof grade?
- 1) thermal conductivity of low polyurethane sandwich panel composite board thermal conductivity is small, good insulation properties, is the best insulation materials. 2) panel appearance, easy to install 3) Polyurethane sandwich panel fire resistance is good 4) Polyurethane sandwich board non-toxic and tasteless 5) use a wide temperature range 6) waterproof, moisture Polyurethane sandwich panel shape beautiful, the overall effect is good, it sets load, insulation, fire, waterproof in one, and no secondary decoration, quick and easy installation, short construction period, comprehensive benefits, and has a good price advantage, Widely used, highly potential energy efficient building envelope materials, but also the Ministry of Construction to promote and promote a new energy-saving sheet.
