Graphite EPS foam insulation board China supplier Product Characteristics
2)High compressive strength, can absorb wall deformation and reduce the wall cracking;
3)Good dimensional temperature, easy to shrink deformation;
4)The waterproof performance is excellent, and the molecular structure has no gap, which solves the problem of infiltration and condensation of materials, and the system lives long；
5)Tensile strength can effectively resist the tension and shear force caused by negative wind pressure or heavier decorative layer；
6)Fire resistance level B1/B2, not spread, not spread, not burning；
7)Good stickup, applicable to all kinds of wall insulation, can be sanded, the construction is convenient.
