Graphite polystyrene board

Graphite EPS insulation board is the latest generation of insulation material made through chemical refining on the basis of traditional EPS. Graphite EPS insulation board because of the special graphite particles, can reflect and absorb infrared ray, so that the thermal insulation performance is at least 30% higher than the traditional EPS, thermal conductivity can reach 0.035, combustion performance level can reach B1 level.
