Applications currently available foam (polystyrene board) about these types of species: a: Press flame retardancy classification: 1, ordinary type of foam (flammable), also known as ordinary polystyrene board. 2, B2 retardant foam (flammable) b2 grade polystyrene board. 3, B1 retardant foam board, (flame retardant) b1 grade polystyrene board. No matter what kind of final are not non-combustible, flame-retardant and non-combustible hope you distinguish between the two concepts. 2: Pressing the density classification: 1, the first class density greater than or equal to 15 kg, less than 20 kg. The second category, approximately equal to 20 kg less than 30 kg, the third category: not less than 30 kg less than 40 kg. The fourth category, not less than 40 kg less than 50 kg and so on. White object B1 polystyrene foam board, B1 grade polystyrene board, which is derived from a volatile liquid foaming agent of polystyrene particles and special additives, heating advance in the mold foam molding . B1 grade polystyrene board has the characteristics of a fine closed cell structure and flame-retardant effect of B1; B1 grade polystyrene board is mainly used for building wall insulation, roof insulation, composite board insulation, cold storage, air conditioners, vehicles, ships floor heating, decoration carving, very versatile. Advantages B1 grade polystyrene board B1 grade polystyrene board with light, heat insulation, low temperature resistance, good fire-retardant properties, have a certain flexibility, minimal water absorption. B1 grade poly board exterior insulation system with excellent insulation properties, good water resistance and compressive strength, impact resistance, can effectively solve the problem of cracking and leakage on the wall. B1 grade poly board exterior insulation system in winter to avoid thermal bridges, greatly reduce indoor heat loss through exterior walls; B1 grade poly board exterior insulation and finish systems can greatly reduce summer solar radiation from the outer wall and the heat transfer to the interior, thereby enabling heating, air conditioning energy consumption decreased. B1 grade poly board exterior wall insulation system light weight, energy-saving effect, can reduce energy consumption and protect the main structure, but also to extend the life of the building. B1 grade poly board exterior insulation system for a building covered with a warm, reliable and durable coat, the majority of real estate developers, thermal insulation building design and construction unit of choice for thermal insulation system. With the development of building energy efficiency, and its excellent performance gradually accepted by the market, energy-efficient building will become the future development direction. Polystyrene board Main Specifications: Density range: 15-30kg / m3 length: 1000-6000mm width: 200-1230mm Thickness range: 10-1230mm Shen Yang-Ming Hui of insulation materials Limited production of "Auspicious card" polystyrene foam insulation board, commonly known as "EPS or benzene board" by polystyrene beads, pre-made, curing, molding, drying, cutting and other processes is made. It can be made of different densities, different shapes of foam products, and can be processed into different thickness of the foam sheet can be divided into common type of flame retardant and graphite. Widely used in laying the building foundation wall insulation, cold insulation, building backfill layer, color-coated steel member building insulation, airport runways and highways have control tiles heat up, shrink the state, causing the ground surface was cracking, swelling advantage drum. It is known as a pioneer in the insulation industry. Specific procurement standards, please call the business, detailed communication, sincere cooperation!
