The main characteristics of foam packaging and design selection points 1), light weight, and has a certain compression, tensile strength, supported by its own strength can wipe the surface protective layer does not need to pull to pieces, to avoid thermal bridges. 2) EPS plate in a density of 30 ~ 50 kg / m3 range, minimum thermal conductivity values; average temperature at 10 ℃, foam insulation box Qingdao, a density of 20kg / m3, the thermal conductivity of 0.033 ~ 0.036W / (m · K); a density of less than 15 kg / m3, thermal conductivity increases sharply with decreasing density; density EPS plate 15 ~ 22 kg / m3 is suitable for external insulation. 3) When used for exterior and roof insulation, foam insulation box Linyi, generally do not produce significant moisture problems. But long-term EPS plate side in hot and humid environment, the other side is cold environment steam poor materials and are thoroughly closed; or when the roofing layer fails, EPS board could seriously damp, causing its insulation properties severely reduced. 4) When used in cold storage, air conditioning and other low-temperature pipe insulation, vapor barrier must surface of the EPS-board. Impact strength and toughness in the choice of material is a very important consideration, but also the main requirements rotomolding foamed article. To meet this requirement, foam insulation box, which is widely used in rotomolding foaming process. In addition, polypropylene (PP), PVC plasticized powder, ethylene - vinyl acetate copolymer (EVA), ethylene - butyl acrylate copolymer (ECTFE) and nylon, ABS, ethylene - trifluoroethylene copolymer (which is equal to also used for special applications. prospects for the development of raw materials also includes polyphenylene ether (PPO), ABS and ABS- polycarbonate (pc) alloy, polyether ether ketone (PEEK), polyphenylene sulfide (PPS) and glass . reinforced nylon, etc. In recent years, the metallocene catalyst synthesis provides a good raw material for the rotational molding PE foam tank foam insulation cost-effective, large plate foam insulation foam box |.. much foam | foam insulation box by the Shandong Rizhao There are foam Ltd. to provide foam insulation box |. much foam | foam insulation foam box Rizhao Shandong great Ltd.
