CE Certificated PU Sandwich Panel Making Machine Line for Coldroom Wall Panel Production

Product Feature:

Rigid polyurethane has low thermal conductivity and good thermal performance. When the rigid polyurethane capacity is 35~40kg/m3, the thermal conductivity is only 0.018g~0.023w/ (m. k), which is about half of EPS, which is the lowest thermal conductivity of all insulation materials at present.

Rigid polyurethane has moisture-proof and waterproof properties. Rigid polyurethane has a closed cell ratio of over 90%, which is a hydrophobic material, and will not increase the thermal conductivity due to moisture absorption, and the wall will not penetrate water.

Rigid polyurethane is fire-resistant, flame-retardant and resistant to high temperatures. After adding flame retardant, polyurethane is a kind of flame-retardant self-extinguishing material. Its softening point can reach more than 250 degrees Celsius, and it decomposes only at higher temperatures. In addition, polyurethane foams when it burns. Ash is formed on the surface. This layer of ash helps insulate the foam underneath and can effectively prevent the fire from spreading. Moreover, polyurethane does not generate harmful gases at high temperatures.

PU sandwich panel production process methods There are basically two methods of PU sandwich panel production process, namely continuous production and discontinuous production.

Discontinuous PU sandwich panel production line is suitable for special shaped products that cannot be continuously produced, or the production volume is not enough to invest in continuous equipment. In the discontinuous process, the materials are processed separately, which means that after the surface material is formed, it is cut to the required length, and then assembled together into the laminator, and the foam is injected between the surface materials to generate a predetermined shape PU sandwich panel.
