Introduction of Foam Board

Foam board is also known as EPS board, which is the expandable polystyrene particle containing volatile liquid foaming agent, and eventually form foam molding by the advanced heating in the mold. Polystyrene foam board has the characteristics of a fine closed cell structure; polystyrene foam boards are used in the building wall and roof insulation, composite panels insulation, cold storage, air-conditioned vehicle, ship insulation, floor heating, decorating carving and so on, therefore, it is widely used in various aspects.

The Advantages of Foam Board

The polystyrene foam board has the characteristics of lightweight, insulation, insulation resistance, low temperature resistance, and it has a certain degree of flexibility and minimal water absorption. Polystyrene foam board exterior insulation system has superior insulation properties, good performance of the water-repellent, crush-resistant and impact resistance, and it can effectively solve the body cracking and leaking water problems of the wall. Polystyrene foam board exterior insulation systems can avoid thermal bridges in winter and greatly reduce the loss in indoor heat through the exterior wall; the weight of the wall of the polystyrene construction foam board exterior insulation systems in summer can be greatly reduce the heat which is conducted to the indoor by sun radiation exterior wall, thereby enabling the heating, air-conditioning energy consumption decline. Polystyrene foam insulation board exterior insulation systems wall has light weight with significant energy savings, can reduce energy consumption and protect the main structure, but also extend the working life of the building. Polystyrene foam insulation board exterior insulation system cover a warm, reliable, durable coat to the building, is the energy-saving thermal insulation system of choice for architectural design and construction units. With the continuous development of building energy efficiency, its excellent performance is gradually accepted by the market, and the energy-saving buildings will be the direction of future development.

Challenges for the Foam Board Industry

The short term shrinking of the civil housing market is the biggest challenge of the current North American building insulation materials market. Affected by the financial crisis, civilian housing market in North America is rapidly shrinking, and the negative impact of the civil housing market shrinking on the North American building insulation materials market will continue for a long time. There are some technical problems in building insulation material itself, due to higher cost of recovery and the lower recovery rate of the insulation material, some insulation materials aids are difficult to be separated in the recovery, which also led to poor product quality in the recycled insulation material reproduction, limiting the application of recycled materials in some areas. There are some harmful substances on human health in the building insulation material products, such as the adhesives used in mineral wool forming may contain harmful volatile organic compounds. These technical problems will affect the building insulation materials.
Food Packaging Foam Board

Foam boards are ideal food packaging materials. The foam board sheet, because of its thermal stability and thermal insulation, has become the senior food packaging alternatives. Density of 0.5-0.7g/cm3, foam board sheet in a thickness of 0.5-1.5mm is the production of high rigidity and good heat-insulating tableware (plate, bowl), beverage cups and the like raw materials; the 0.2-0.5g/cm3 density and thickness 1.0-3.5mm foam board sheets are used for meat, food packaging materials (such as processing into pots, plates, used in the applesauce, lactic acid casein, low acidity food packaging) and bottle gasket. German co-extrusion method, density 0.1-0.5g/cm3, and the thickness of 1-3.5mm foam board sheet. These foam board sheets can be used for food or meat packaging, can also be used for the production of shell products and a variety of utensils (plates, dishes, bowls, boxes, etc.). Monolayer foam board sheet from May 1999 to be applied to all kinds of microwave tableware and security, and more resistant to heat, and started in 1998, it is widely used in the manufacture of food packaging containers.

Building Thermal Insulation Foam Board Material

The foam board sheets have low thermal conductivity and thermal heat insulation properties, so the construction foam board is usually used as advanced insulation material applications. Steam pipe insulation materials begin to use foam board, and as the air conditioning pipe insulation materials are also under study. According to statistics, China's domestic air-conditioner production in 2000 reached 18.26 million units, and the foam board with good heat resistance is used as the air conditioning pipe insulation has a huge market. Foam board insulation materials also can be used as a petrochemical pipelines, water pipe freeze protection insulation kits, as well as hot water pipes, conservatory, tank heat insulating material. Due to the high heat resistance of the foam board, the foreigners widely use it for the heat resistance and meet the requirements of the occasion of the foamed sheet, such as for the 90-120℃ heat carrier cycle battery heat insulating material, the engine room and workshop insulation materials, heating pipe insulation kits. In short, in all a portion of the heat problem exists in the use of foam board, a foam board material can be used.

Cushion Packaging Foam Boards

The most important performance in the cushion packaging requirements is energy absorption. Foam board molded products can be used to withstand high loads and repeated shock protection capability than can be made of polystyrene moldings or foam superior. Foam board can be used for computer, medical instruments, precision instruments, audio-visual materials, cameras, glass, ceramics, arts and crafts, a variety of household appliances such as shockproof cushion packaging, in order to avoid injury and damage suffered during transport. Further, the foamed sheet also has advantages and can be directly recycled, the texture is soft and will not damage the surface of the packaged objects. According to statistics, in 1997 only two color TV and color picture tubes on the use of foam boards of over 20,000 tons.
