What is graphite polystyrene board?

Graphite polystyrene board: the full name of graphite molded polystyrene foam (commonly known as "black foam" or "blackboard", abbreviated as SEPS), which is widely used in the internal and external wall insulation system of buildings; Combustion performance of graphite polystyrene board: reaching B 1 grade (flame retardant); Not only the flame retardant used in ordinary polystyrene board is added (volatilized at high temperature), but also the infrared reflector mixed in the raw materials makes the fire prevention performance stronger, more stable and reliable. Graphite polystyrene board is the latest generation of thermal insulation material refined by BASF company imported from Germany with more advanced processing technology, which greatly improves the thermal insulation performance of the material and is suitable for low-energy buildings with high energy-saving standards. Product features: HN-SEPS insulation board not only has all the properties of ordinary insulation board, but also has the following characteristics: 1, and the fire resistance grade reaches flame retardant B 1; The combustion performance of HN-SEPS insulation board completely reaches B 1 grade, and it has good fire resistance. 2. Stronger thermal insulation capacity: HN Sipes thermal insulation board is made of classic thermal insulation material expanded polystyrene by chemical methods, and its thermal conductivity is ≤0.032. Its thermal insulation capacity is 30% higher than that of ordinary EPS, which is helpful to improve energy efficiency and reduce carbon dioxide emissions. 3. The cost of the same effect is lower: the outstanding thermal insulation ability of HN-SEPS insulation board is especially obvious at low density. Compared with conventional EPS insulation board, it saves cost. High cost performance, the same effect, compared with other fire-proof external insulation systems, more cost-saving. Simple construction and good system integrity: the construction method of graphite polystyrene board external wall thermal insulation system is the same as EPS thin plastering external wall thermal insulation system, with high system integrity and durability, which is suitable for external wall thermal insulation projects requiring B 1 grade polystyrene board for fire protection. Performance characteristics: apparent density: 18 ~ 25 kg/m, thermal conductivity: ≤ 0.032; Combustion performance: classification
