Hydrophobic, moisture-proof
Water absorption is an important parameter to measure thermal insulation material. After absorbing water, the thermal insulation performance of the thermal insulation material decreases. In the
case of low temperature, the water inhaled is easy to freeze, which destroys the structure of the thermal insulation material, thus reducing the compressive resistance and thermal insulation
performance of the plate. Because polystyrene molecular structure itself does not absorb water, plate molecular structure is stable, no gap, solving other materials leakage, infiltration, frost,
condensation and other problems.
