  • High quality PU resin for shoe sole

  • Very cometitive price in the market

  • Timely after_sale service of technician


  • 1.Application of Polyurethane sole material

    Polyester polyol or polyether polyol as component A, Isocyanate as component B, Catalyst as component C

  • 2. Raw material Storage Conditon

    Materials should be stored in the cool and well-ventilated places which will be prevented from being filled with water and open flames.

  • 3.Raw material melting method

    Component A: 60-70°C for 6-8 hours.   37-45°C
    Component B: 50-60°C for 5-6 hours.40-48°C
    Component C: No need to heat.
    Mold temperature  40-50°C

  • 4.Additives ratio method

    The required amount of catalyst, pigment and hardner are added into component A. Timely put them into component A tube in the foaming machine after mixing them well by the high-speed agitator. Tighten and seal it.


  • 1.Matching ratio is based on the optimal matching value which will vary with the category and additive amount of paint additives added.

  • 2.Free foam density will vary with the seasons (temperature, humidity).

  • 3.Stripping time will be extended with the increase of the thickness of moldings.

  • 4.Folding enduurance conditions: bending angle is 90 degrees and the frequency is 80 times/min * 40 thousand times


  • Shoe sole is broken

    Inappropriate ratio/ demolding happens too fast/ mold temperature is too low

  • Shoe sole shrink

    Inappropriate ratio/ density is too low/ adding too much water

  • Bubbles in the shoe sole

    The cleaning liquid or resin material leaks out/ unstable pressure/ the filter is blocked

  • Desquamation

    Raw material is expired/ density is too low/ pouring method is wrong/ mold design problem

  • Unstable mixture ratio

    Component A and B temperature differs too much/ pump speed differs too much/ machine head is blocked
