It is made of polystyrene resins and other additives manufactured by extrusion process has continuous and uniform surface and obturator cellular structure sheet foam boxes, planks of these cellular structures, will not appear gap, this obturator Insulation material structure can have different pressures (150-500Kpa) foam box outlets, also has the same low thermal conductivity (only 0.028W / MK) compression performance and excellent thermal insulation and enduring, compressive strength up 220-500Kpa. Its mechanical properties are unmatched EPS foam box processing, polystyrene foam board low water absorption, high water absorption will cause deterioration of insulation foam box production, so as insulation materials, water absorption is a very important technical indicators, closed-cell structure, and cellular structure of the XPS panels can help to maintain a low water absorption features, so you can effectively prevent the penetration of water molecules. Foam box outlets, Lee Chang-foam boxes, foam plastic first brand Zhucheng Hua Yong Hua Yong provided by Zhucheng Plastic Foam Factory. Zhucheng Yong Hua Plastic Foam Factory (www.zchyps.com) strong, credible, Shandong Weifang industrial products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Zhucheng Yong Hua Plastic Foam and you hand into the brilliant, for a better future!
