The difficulties faced by the polyurethane industry

several fires have also charged the polyurethane industry with being the "culprit". In this regard, Zhu Changchun, Secretary General of China Polyurethane Industry Association, felt sad. He believed that the polyurethane industry was originally a good building exterior wall insulation material, which had many advantages, such as thermal insulation, waterproof, sound insulation, vibration absorption, etc Stopping experimental explosive functions is the most popular product in the foreign construction market, but it has no choice but to be demonized by the fire in China

for many years, polyurethane, known as the "noble" of building exterior wall insulation materials, has been playing a minor supporting role in the industry. According to the statistics of China Polyurethane Industry Association, by the end of 2013, the polyurethane industry accounted for less than 10% of the building exterior wall insulation material market

however, on December 3, 2012, the Ministry of public security revoked the "strictest thermal insulation material policy in history" and "Document No. 65", from mandating that "the external thermal insulation materials of civil buildings should be applied with materials with combustion performance of class a", to "the external thermal insulation materials of new construction, reconstruction and expansion projects should not use inflammable materials (class B3), and the use of inflammable materials should be strictly restricted (B2, which ensures the experimental accuracy level)", which is equivalent to loosening the binding of organic materials, Also let polyurethane manufacturers see some dawn

but another difficulty still lies ahead of the polyurethane industry, that is, its price is several times higher than that of traditional insulation materials EPS and XPS. In this regard, Xinbo, the marketing manager of Wanhua Chemical Group Co., Ltd., believes that the polyurethane industry depends on the comprehensive cost performance, not just the price of products

therefore, a higher housing acquisition rate has become a major selling point of the polyurethane industry. In first tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, manufacturers of polyurethane industry even shouted the slogan "polyurethane for exterior wall insulation is a negative cost" to real estate enterprises

he calculated a detailed comprehensive account for: the two materials are several times worse only in terms of unit price per cubic meter, but if according to the standard of 65% building energy efficiency, the thickness of polyurethane with lower thermal conductivity needs 6-8 cm. It is expected that the localization replacement of domestic high-end market will reach a climax in 2017-2018. The thickness of EPS and XPS needs 10-13 cm, and the thickness difference between pasted on the outer wall is twice. Since almost all cities in China sell houses according to the building area (except Chongqing), the use area of houses using polyurethane is 1%~1.5% higher than that of houses using EPS and XPS plates. "Weighing the relationship between material prices and house prices, the polyurethane industry is still beneficial in general."
