Thermal insulation
Waterproof performance
An important factor in measuring the insulation performance of insulation materials is their water absorption rate. Once the insulation material absorbs water, its insulation performance will weaken. At lower temperatures, water can easily freeze when it enters the material board, causing a structural change in the plastic board and a decrease in its resistance and insulation performance. The chemical molecular structure of the medium dry board itself does not absorb water and has a stable structure without gaps, so there will be no water leakage, infiltration, frosting, condensation or other situations like other materials.
Stability and corrosion resistance
The structure of extruded polystyrene board is stable, so even if it is used for a long time, it will not age, decompose, or produce harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption and corrosion, causing its performance to decline. It can still maintain its superior performance in high temperature environments, and the service life of extruded insulation board can reach about 60 years.
