Advantages of Different Sandwich Panels

The Sandwich Panel is composed of two layers of forming metal panel or other materials and also the inner core, that is straight foamed and cured of polymer insulation materials. The sandwich panel is simple to set up, lightweight and effective. Filling system can also be closed with bubble molecular structure, it can prevent condensation of water vapor. The forming of out plate is totally considering the structure, strength requirement and beauty, the surface shape is flat to meet various requirements. Here is introduction of several kinds:

1. EPS Sandwich Panel: It is most widely utilized in market at present, because it is transportable and durable, easy to set up and inexpensive. Its fire rating is B1, tongue-and-groove type effective width is 1150mm, thickness is 50mm-200mm, and its length is customized. It applied to steel structure workshop, simple roof, wall, ceiling and partition of clean air.

2. Polyurethane Sandwich Panel: It's also named PU sandwich panel, it also has numerous advantages of EPS, and it is difficult to burn and not brittle, shrink is extremely little in ultra-low temperature, so it is most suitable for cold storage. But its cost is higher and the fire rating is only B.

three. PF sandwich panel: It is internationally recognized probably the most promising new thermal material. Simply because this sort of new material will not burn within the fire, not melt, and won't send out toxic fumes. PF sandwich panel has benefits of light, non-toxic, non-corrosive, heat preservation, energy-saving, sound insulation, and low cost. It isn't foamed with freon, so there's no environmental pollution. Its complete performance is presently unmatched by all sorts of insulation materials. PF sandwich panel is usually used in hotels, apartments, hospitals and other senior and central air conditioning method of high-rise developing insulation (Hong Kong senior building central air conditioning method most utilized PF sandwich panel) in current years.

4. Rockwool Sandwich Panel: The brief name is RS sandwich panel. This panel is full played the unique properties of its core supplies: rock and wool. It has substantial effect around the fire prevention, heat preservation and heat insulation, sound-absorbing, sound insulation, and so on. In fireproof performance, rock wool sandwich panel utilizes the raw materials, production technology and formula, numerous tests show that it has the fire-resistant capacity of greater than 1000 ℃. Its sound insulation and sound-absorbing effect is outstanding: the reduction impact for noise transfer is significant, it is particularly suitable for a place exactly where there will be flight flying by. In addition, using RF sandwich panel, the noise of the rain and hail influence towards the structure of the roof will probably be also decreased considerably indoor.
