Raphite Grade – S – Flame-Retardant Panels

• The flame retardant grade reaches Class B1 (GB8624-2012), and the prepared panels and molded products have self- extinguishing fireproof performance;
• The thermal conductivity is lower, with a typical value of 0.033 W/(m·K), resulting in better thermal insulation performance;
• The typical density of the products after foaming;
• 15-35 kg/m3, with a high expansion ratio;

Product Features：
Color: Uniform black or dark gray. Graphite polystyrene foam is made of imported new materials and innovative processes.In addition to all the properties of ordinary EPS insulation boards, it also has the following advantages:Fire

resistance reaches the difficult-to-burn Class B1 level.Stronger thermal insulation capability.Lower cost for the same effect, more eco-efficient, and reduces environmental burden.Fire resistance reaches the difficult-to-burn Class B1 level: The combustion performance of SEPC fully meets the indicators of Class B1 (GB8624-1997 Grading Method for Combustion Performance of Building Materials), demonstrating excellent fireproof performance.
