EPS sandwich panel for new material

Detailed Product Description sandwich panel 1.FireProof ,Water Proof 2.Light Weight,Sound Insulation 3.Fast construction 4.Heat insulationName:sandwich panel Brand:XINFENG Place of Origin:China(Mainland) Size(L*W*T):(1500-3000)*610*(60/75/90/120/150/180)mm Composition: calcium silicate(face panel) & cement and EPS(core) & calcium silicate(face panel) Advantage:Energy conservative and environmentprotective,optimal features against shock and impact,light weight,fire proof,waterproof and moistureproof,sound insulation,easy to install,increase productivity effect Uses: Used in concrete construction and steel construction for interior and exterior decoration. Description: This kind of panel is formed by 2 surface boards filling with the mixture of polystyrene core and cement in the middle .Its surface board is calcium silicate board,which makes it heat resistant ,water proof ,has optimal features against hit and impact ,and has high-intensity. The surface boards ofXINFENG wall panel with thickness of 5mm,undertaking shock and impact from outside ,hence stronger the panel itself ,and because of its special 3-in-1composition ,it also prenvents the panel from distortion . The use of polystyrene in filling of the panel reduces the weigh of panel,and makes it heat insulation ,sound insulation ,water proof and longer durability .The characteristic of polystyrene also keeps the panel away from decompose ,moldy and insects.When thesepolystyrene combins with cement and evenly distributed inside the filling of the panel ,the cement around them automate forms the shape of alveous,which it spreads out pressures of hit and impact from outside and easy to be spiked,nail in and carrying hanging weight.
