Softlon features and functions
  • Water resistance
    Water absorption

    Closed cell foam made of polyolefin resin having low water absorption impregnable to water

  • Strength

    Widely used as a sturdy yet flexible material with superior heat resistance over non-crosslinked foam

  • Flexibility

    Resin’s intrinsic softness and closed cell structure providing reasonable bouncing and cushioning

  • Heat resistance

    With excellent heat-resistance, polypropylene (PP) resin has minimal thermal shrinkage even in the high temperature range.

  • Thermal insulation

    Foam containing a large amount of air with minimized convection resulting in low thermal conductivity and superior thermal insulation performance

  • Thinness

    Sekisui’s proprietary thinning technology realizes thin foam of 1 mm or less.

  • Shock absorption

    With the inherent flexibility of the resin and the bubble cell structure of the foam, the physical high-speed pressure (shock energy) is evenly dispersed.

  • Sealing of uneven surfaces

    With its flexibility, the foam seals uneven or sharp surfaces to achieve high sealing property.

  • Thermoformability

    Polypropylene (PP) resin has excellent heat-stability, Softlon SP can withstand high temperatures during molding, enabling highly deep drawability.

  • Smoothness

    An even and clean surface with finer cells compared to chemical crosslinked foam, suitable for adhesion and coating

  • Electrical characteristics

    Closed cell foam containing a large amount of air providing excellent dielectric strength and low permittivity.

  • Chemical resistance
    Oil resistance

    With superior resistance against acids, alkalines, organic solvents, and other chemicals, used in many industries

  • Low environmental load

    Being halogen-free, generating no toxic gases when burnt

  • Workability

    Excellent shape stability realizes various processing.
