S-33

Graphite polystyrene (extrusion method)


S-33 introduced the infrared absorbing material, natural flake graphite, into the polystyrene polymer by extrusion process. The graphite particles absorbed and reflected the radiation energy in the foamed beads, which improved the thermal insulation function of the flexible polystyrene core. The thermal conductivity of S-33 is less than 0.033W/M.K, the thermal conductivity of ordinary EPS is 0.039W /M.K, and the thermal insulation performance of S-33 is improved by more than 20%.
