Product Details
EPS sandwich panel, also known as polystyrene sandwich panel, is a board composed of two layers of inner and outer metal sheets and a polystyrene foam sandwich layer in the middle. The inner and outer layers are mostly glass fiber reinforced plastic boards, but some are made of other materials such as color steel plates, while the sandwich layer is specially treated polystyrene foam.
The production process of EPS sandwich panel mainly includes the steps of pre-foaming, aging and board forming of EPS particles. EPS particles are expanded by high-temperature steam heating, and then aging treatment is performed to enhance their elasticity. Finally, the particles are squeezed and fused together to form a board in the molding machine through processes such as steam heating and vacuum cooling.

Product Features
- Thermal insulation: Polystyrene is a good thermal insulation material with low thermal conductivity, which can effectively prevent heat transfer, making EPS sandwich panels have good thermal insulation effect.
- Lightweight and high strength: EPS sandwich board is relatively light, but its strength and durability are relatively high. It can withstand a certain load and is suitable for various building structures.
- Corrosion resistance: The surface of the fiberglass plate has a layer of excellent gel coat, which has good chemical stability to the atmosphere, water and general concentrations of acid, alkali, salt and other media, making the EPS panel has excellent corrosion resistance.
- Good processing performance: EPS sandwich panel can be cut, spliced and processed as needed to adapt to different building structures and design requirements.
- Economical price: The cost of polystyrene materials is relatively low, so the price of polystyrene sandwich panel is relatively affordable and has a high cost performance.
