Publish Time: 2025-01-27
As a lightweight and efficient thermal insulation material, foam-grade EPS (expanded polystyrene) polystyrene has been widely used in many fields such as construction, packaging, and cold chain transportation. Its significant thermal insulation performance makes it stand out among many materials.
EPS polystyrene foam board is made by pre-heating expandable polystyrene beads and then heating and molding them in a mold. This unique production process gives it an extremely low thermal conductivity, usually between 0.038-0.041W/(m·K), which can effectively prevent heat transfer. This means that in the cold winter, EPS foam board can reduce indoor heat loss and maintain indoor temperature stability; in the hot summer, it can effectively block the intrusion of external heat, reduce indoor temperature fluctuations, and provide residents with a comfortable indoor environment.
In addition to the low thermal conductivity, the thermal insulation performance of EPS polystyrene foam board is also reflected in its unique closed-cell structure. This structure makes the foam board full of a large number of independent bubbles, which can effectively isolate air convection and further reduce heat transfer. At the same time, the presence of bubbles also makes the EPS foam board have certain sound insulation properties, which can effectively absorb and isolate external noise, creating a relatively quiet environment for the room.
In addition, the thermal insulation performance of EPS polystyrene foam board is also reflected in its light weight and easy processing characteristics. This material is light in weight, easy to construct and operate, and can reduce the labor intensity of construction workers. At the same time, it is easy to cut and can be flexibly processed according to the different shapes and size requirements of the exterior wall, which helps to improve construction efficiency. This flexibility enables EPS foam board to be widely used in various building structures, whether it is a multi-story residential area or a high-rise building exterior wall insulation system, it can achieve good insulation effect.
In general, foam-grade EPS polystyrene has shown significant advantages in thermal insulation performance with its extremely low thermal conductivity, unique closed-cell structure, and light weight and easy processing. These advantages make EPS foam board one of the indispensable materials in the fields of construction, packaging, cold chain transportation, etc. With the advancement of science and technology and people's increasing requirements for environmental protection and energy conservation, the application prospects of EPS polystyrene foam boards will be broader.
