• 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

    • Summary:

      The increase of the aromatic ring density in the Pu segment increases the rigidity of the segment and increases the intermolecular force, so that the thermal decomposition temperature of the polymer increases. Oxazolidinone can be synthesized from is...

    • Summary:

      Now more and more people buy a car, so the car cushion has become more and more hot, then you know what car cushion is what? The following is the China Chamber of the report by the small series for you finishing the car cushion industry definition an...

    • Summary:

      1, material inferior: because the market price of waterproof material competition, resulting in many domestic polyurethane material manufacturers in the waterproof
      2, the material cut corners, which will make the waterproof material itself physica...
