Relaxation of restrictions on organic insulation materials takes the lead

In order to quell the chaotic situation between inorganic and organic thermal insulation materials in the domestic building thermal insulation material market in recent years, the State Fire Administration of the Ministry of Public Security recently issued the 'Notice on the Fire Supervision and Administration of Civil Building External Thermal Insulation Materials' (Circular 350) to cancel the original Circular 65 no longer limits the use of B1 organic building insulation materials, which can be widely used in various high-rise buildings. At the same time, it puts forward higher requirements for building insulation systems, such as the installation of fire barriers.　　 Some market participants analyzed that the implementation of Circular 350 will restart the depressed market demand for organic building insulation materials, and put my country's building energy conservation business on the fast lane. Huasu Plastic Machinery www., a EPE foam machine factory with a production capacity of 1 million tons of polystyrene, is expected to take the lead.　　 It is reported that my country is currently the largest construction market in the world, with a construction area of u200bu200b40 billion square meters and an annual increase of 2 billion square meters. Among the new buildings, more than 95% are high-energy buildings. The organic thermal insulation materials represented by expanded polystyrene (EPS) have always been mainstream building thermal insulation materials due to their light weight, high density, and good thermal insulation. Among them, EPS and XPS (extruded polystyrene) Styrene plate) has a market share of more than 80% in the building insulation materials market.　　Hua Plastics Press Chairman Zhao Shiwu said that the promulgation and implementation of Document 350 of the State Fire Administration will fully release the market space for organic building insulation materials such as expanded polystyrene and polyurethane. The expanded polystyrene products produced by Huasu Plastics Machinery's EPE foam machine passed the national inspection in July 2011 and reached the B1 level. The company will gradually increase the output of B1 products according to market demand. 'With the acceleration of urbanization, Huasu Plastic Machinery is confident in the market prospects of expanded polystyrene building insulation materials that meet safety requirements, good insulation performance, and cost-effectiveness. Therefore, the market demand for EPE foam machine is also promising. 'Zhao Shiwu told reporters.　　 According to data, my country’s current standards divide external wall insulation materials into 4 grades: Class A (non-combustible), Class B1 (flammable), Class B2 (flammable) and Class B3 (flammable). In the market, inorganic thermal insulation materials represented by rock wool, glass wool, and perlite are popular because of their better flame retardancy, but their low thermal insulation performance, complex construction technology and high cost are widely used by developers and construction units. To criticize. Against the background of painful choices regarding the flame retardancy and thermal insulation properties of building insulation materials, local government authorities have successively issued local building insulation materials use specifications, which to varying degrees restricts organic insulation materials with a combustion performance of B (B1/B2) level. usage of. At the same time, the construction market's mandatory requirements for the thermal insulation performance of thermal insulation materials are also stubbornly resisting the expansion of inorganic thermal insulation materials. This has led to a melee between inorganic and organic thermal insulation materials in the construction market.
