EPS Sandwich Panel

EPS sandwich panel (Polystyrene sandwich panel), also known as foam sandwich panel, has a core made of lightweight foamed polystyrene material, with steel plates attached to both sides. During the manufacturing process, a special machine will apply special glue with a brush. The two glues will react quickly in a short time and penetrate into the foam gaps to a certain extent, thus achieving a strong bond between the layers of the foam sandwich panel.

EPS sandwich panels can be understood as expandable polystyrene. According to actual application requirements, some EPS foams will have flame retardants added to enhance their fire resistance, while some will not. Regardless of whether flame retardants are added, EPS foam itself still has excellent thermal insulation properties.

1. Excellent thermal insulation performance: The filling layer material (EPS) plays the role of a thermal insulation layer in the sandwich panel. These materials have low thermal conductivity, effectively slowing down heat conduction and thus providing good thermal insulation properties. Therefore, in summer, it can prevent outdoor high temperature from penetrating indoor heat, while in winter, it can reduce indoor heat transfer to the outside, achieving energy saving effects.

2. Good sound absorption and sound insulation effect: The material of the filling layer (EPS) also has good acoustic properties, which can absorb noise and isolate sound transmission, providing good sound isolation effect.

3.Durable and corrosion-resistant: The outer panels are usually made of metal (such as steel, aluminum) or materials with anti-corrosion coatings, giving the EPS sandwich panel good durability and corrosion resistance. This means that the sandwich panel can be used stably for a long time in harsh environmental conditions, such as oceans, chemical plants, etc.

EPS sandwich panel is used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields. In order to meet the national building energy conservation requirements, it is mainly used for external wall insulation and internal external wall insulation.
