Graphite polystyrene foam board

Product Description


Graphite EPS  is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the material's resistance to the flow of heat, or R-value. Most polymer-based foams exhibit a greater ability to slow the movement of heat as the temperature decreases.

Graphite polystyrene foam insulation board delivers maximum energy efficiency, cost effectiveness and sustainability. Architects, contractors and builder-owners benefit from it because of the special advantages this material offers.

Graphite EPS foam insulation board China supplier Product Characteristics

1)Good thermal insulation performance, low thermal conductivity, is a highly efficient and energy-saving thermal insulation material;
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.
