The structure of the polystyrene sandwich panel is mainly composed of FRP panels on the inside and outside and polystyrene foam in the middle. This structure is made by German vacuum technology high-pressure lamination, the surface is smooth, the dirt can be easily removed, the color is bright, and it has excellent gloss retention.

Inner and outer materials: the inner and outer sides are glass fiber reinforced plastic plates, the surface of this material has a layer of gelcoat with excellent performance, which has good chemical stability to the atmosphere, water and general concentration of acid, alkali, salt and other media, high surface finish, excellent gloss retention, no discoloration, corrosion resistance, anti-sunlight, anti-aging.


Polystyrene sandwich panels are widely used in various construction fields, such as cold storage assembly. Especially in the assembly of cold storage, the double-socket polystyrene sandwich panel can improve the thermal insulation performance of the cold storage and reduce energy loss due to its tight socket design.
