After the edges are sealed, the overall water absorption rate is ≤4%(industry standard), avoiding traditional plates caused by moisture. Mold and deformation problems, suitable for high-humidity environments (such as ba*ts, coastal areas). Fire and flame retardant: By adding flame retardants, B1 (refractory) or A-class (non-combustible, need to be matched with non-combustible panels such as rock wool composite layers) PU sandwich panels can be produced.
