2. Press hardness classification can be divided into soft, hard and semi-rigid foams three categories: under 23 ℃ and 50% relative humidity, foam insulation box Jiangsu, the elastic modulus of less than 70 MPa foam called the soft foam. In the above temperature and relative humidity, foam insulation box cold storage elastic modulus of greater than 700 MPa called rigid foam.帊 between 70 trillion and 700 MPa modulus of elasticity of foam called semi-rigid foam. Which of foam insulation box low price and good quality. Polystyrene foam board insulation direction 1. The foam wall panels make the moist situation was improving the entire wall temperature 2. normally does not occur condensation inside the wall structure layer 3. improved further enhanced wall insulation 4. extend the performance life of the building. foam board is mainly used for building walls, roof insulation, foam insulation box, composite foam board, insulation board, refrigerator \ air conditioning \ vehicle \ insulation, floor heating, decorating carving ships, etc. very versatile foam insulation box, much foam, foam box incubators from Shandong great sea cucumber foam Limited. Foam insulation boxes, much foam, foam box incubators cucumber foam Ltd. Shandong great (www.rzdayou.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Zhang foot years.
