What does EPS foam board mean (is EPS foam board toxic)
Update: 2023-02-28 16:00 View:
Foam board, known as polystyrene foam board, or EPS board for short, is a polymeric material that is very safe to use indoors at room temperature and does not release any toxic or harmful pollutants. However, it is not resistant to high temperatures. In the event of a fire, for example, where the surrounding temperature exceeds 280 degrees Celsius, the foam board will degrade and produce some toxic substances. Therefore it is not harmful for everyday use.
Properties of foam board
Foam board is made from expandable polystyrene beads containing a volatile liquid blowing agent, which is heated and preheated in a mould. It is also very common in everyday life and is often used as an inner packaging material for furniture and electrical appliances to prevent damage in transit due to its white colour, light texture and ease of cutting. In addition, foam board has good thermal insulation properties and is widely used for building walls, external wall insulation, cold storage, vehicles and boats, floor heating and cold chain transport. However, foam board is not flame retardant, the fire rating is only B2 level, it is easy to burn in case of fire, and will release irritating and harmful gases when burning. Therefore, it is generally used as a sandwich, and other materials are added to the surface.
Advantages of foam board
Foam board has good heat insulation and thermal insulation properties, including extruded polystyrene insulation board thermal conductivity of only 0.028W/(m.k), thermal insulation performance far beyond other materials. Foam board structure is stable, even if used for many years, its thermal insulation performance is still not decay, is the first choice of building insulation materials. In addition, foam boards have hardness and a certain degree of flexibility, so the compression and impact resistance are good, not easy to brittle cracking deformation. Highways, parking platforms, airport runways, and the use of its good impact resistance, but also widely used.
