Its well-balanced basic performance is highly evaluated around the world.
Softlon is a closed cell, physically cross-linked polyolefin foam, which is one of the main products of Sekisui Chemical.
The reason it has been widely adopted over many other products across the world is its high performance in an ideal balance.
Softlon can be adapted to various applications, which has been established a solid position as an industrial standard.
Closed cell foam made of polyolefin resin having low water absorption impregnable to water
Widely used as a sturdy yet flexible material with superior heat resistance over non-crosslinked foam
Resin’s intrinsic softness and closed cell structure providing reasonable bouncing and cushioning
With excellent heat-resistance, polypropylene (PP) resin has minimal thermal shrinkage even in the high temperature range.
Foam containing a large amount of air with minimized convection resulting in low thermal conductivity and superior thermal insulation performance
Sekisui’s proprietary thinning technology realizes thin foam of 1 mm or less.
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.
The thermal conductive filler optimally arranged by our proprietary molding process, and achieves high thermal conductivity.
Polypropylene (PP) resin has excellent heat-stability, Softlon SP can withstand high temperatures during molding, enabling highly deep drawability.
An even and clean surface with finer cells compared to chemical crosslinked foam, suitable for adhesion and coating
Closed cell foam containing a large amount of air providing excellent dielectric strength and low permittivity.
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
Excellent shape stability realizes various processing.
Building & Construction
Having a long history, Sekisui foam is used as a heat insulator, airtight material, and various substrates for houses and general buildings concealed from view.
Sekisui thin foam is used as tape bases for fixing parts for IT devices and components for construction, and in a variety of fields including pharmaceutical.
Sekisui foam is used in a wide range of markets for instrument panels and door trims of car interiors, car electronic devices, railway vehicles, and aircraft where heat retardant is required.
