• Summary:

      Polyurethane foam can be used in chromatographic separation of the column, a column of permeability, easy to install the simple, can match the solvent, the higher the capacity of the column and so on. According to the electron micrograph

    • Summary:

      Polyurethane insulation board (chemical name: PU) 1, rigid polyurethane thermal conductivity is low, good thermal performance. When the rigid polyurethane density of 35 ~ 40kg / m3, the thermal conductivity of only 0.018 ~ 0.023w / (m.k), equivalent ...

    • Summary:

      The development of materials experienced structural materials → functional materials → intelligent materials → the process of fuzzy materials. Intelligent means that the role and function of the material can be consciously adjusted
