Compared with EPS, XPS board strength must be high, but compared with the XPS due to the nature of the (brittle) EPS sheet, pasted larger, the possibility of external finishes layer cracking high cheaper extruded sheet, especially paint surface. Flexibility is the material issues extruded board manufacturers, take plaster, the perceptions are usually granted plaster put on polystyrene board, polystyrene board bending and see to what extent is not plastering cracks extruded sheet, flexibility Bend is good not crack a few laps. Similar waterproof material ductility indicators. But on the material itself, the flexibility is better than EPS XPS. According to the national standard brick office record extruded sheet, extruded sheet name is called extruded polystyrene foam insulation, thermal insulation, fire-retardant, compression, environmental protection and other effects are the most important features, the current national standard GB8624 " building materials products of combustion classification "provisions: B2 level is now the minimum requirement retardant XPS board oxygen index ≥26. According to Article XI, "People's Republic of China Fire Law", "building elements and fire performance of building materials must comply with national standards and industry standards" requirement, extruded sheet in the production process need to add flame retardants to prevent and delay severe burning polystyrene sheet. Low extruded sheet, Zibo Rui environment Building Materials Co., Ltd (online consultation), extruded sheet provided by Zibo Rui environment Building Materials Co., Ltd. Zibo Rui environment Building Materials Co., Ltd. (www.lcxps.com) Shandong Zibo, insulation, insulation materials, leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
