The polystyrene board is a rigid foamed plastic board with continuous closed-cell foam extruded by injecting a catalyst into the
mixture of polystyrene resin and polymer at the same time.With the characteristics of high thermal resistance, low linearity and
low expansion ratio, the closed-hole ratio of its structure reaches more than 99%, forming a vacuum layer to avoid air flow and
heat dissipation, ensuring its thermal insulation performance is durable and stable
