The principle of polystyrene sandwich panel is mainly made by using polystyrene foam as the core material, combined with colored steel plate or other materials, and bonding with high-strength adhesive after pressing through an automatic continuous molding machine. This structure makes the polystyrene sandwich panel have excellent thermal insulation performance, water and moisture resistance, corrosion resistance, fire resistance and other characteristics.

Core material: Styrofoam, which has excellent thermal insulation properties and a closed-cell structure that effectively prevents heat conduction and water absorption.
Adhesives: High-strength adhesives are used to firmly bond the outer material and the core material together1.

Thermal insulation: Due to its closed-cell structure and low thermal conductivity, polystyrene sandwich panels have excellent thermal insulation properties and can effectively reduce energy loss.


Fire protection: The outer material is usually non-combustible and meets the requirements of fire protection codes.
