TECHNOLOGY

  • Materials | Microsphere(Fine particles)Homogeneous Microsphere Synthesis

    High-precision control and of microsphere with less variation help to make liquid crystal displays(LCDs) higher definition and smaller.

  • Materials | Functional ResinPhotoactive Material

    We develop strong adhesives with high heat resistance using our unique photosensitive materials technologies. In addition to UV curable adhesives which adhere in a certain period of time after being illuminated with ultraviolet rays, we also have a variety of other products for different uses, such as UV sealing agents.

  • Processing | Precision MoldingHigh-Precision Multi-layer Extrusion

    Using our multi-layer co-extrusion production method, we reduce adhesive deposits and can apply adhesives on adherends without leaving stains. Using variations of substrates and adhesives, they can be applied to optical films of different surface forms, such as matt surfaces and prism surfaces.

  • Materials | Microsphere(Fine particles)Microsphere Surface Functionalization

    The metallic plating layer is formed uniformly on fine resin particles with uniform diameters. In addition, the hardness and elasticity of particles can be configured through the resin core design.

  • Processing | Functional Thin FilmThin Film Depsition by Sputtering

    This is a technology for continuous deposition of inorganic performance films using high-precision sputters. In addition to transparent conductive films, the use of this technology is also spreading to other uses, such as heat reflection and electromagnetic wave shielding.

  • Materials | Functional ResinPolyvinyl butyral resin

    Using our unique technologies, we develop polyvinyl acetal resin products centered on polyvinyl butyral (PVB) resins suitable for various types of binders and primers.

  • Materials | Functional ResinEpoxy resin

    We develop our own epoxy resins for use in adhesive applications requiring high heat resistance and reliability, such as for semiconductors and electronic components.

  • Materials | Functional ResinHigh-Adhesive and Easy-Peelable Material

    This technology produces adhesives that have strong adhesive properties when in use, yet can easily be peeled off using triggers such as light or heat.

  • Materials | Functional ResinAdhesive Compound Design

    Using our unique adhesive design technologies, we achieve the high transparency and reliable adhesion (heat and moisture resistant) required for display uses, such as optical films and cover panels.

Buildings and Infrastructures

We contribute to safety in the construction and infrastructure sectors by supplying products such as resin materials for heat-resistant pipes, as well as fire protection and heat insulation materials.

PRODUCTS

  • Fire-resistant (Protection) material (Fi-Block)

    This is an organic fire-resistant material which expands to form a heat insulation layer during fires. Unlike traditional board or felt-type inorganic fire-resistant materials, it comes in flexible sheets and tapes which can be easily bent or cut. Freedom of design is therefore significantly higher.

  • Chlorinated PVC resin compound (Durastream)

    SEKISUI’s C-PVC is optimally mixed with additives (such as stabilizers and impact absorbers) to produce this compound which can be used to manufacture highly heat-resistant pipes and fittings.

  • Non-flammable polyurethane

    This is a hard, non-flammable urethane foam made from certain resins and flame retardants. It is the first non-flammable resin approved by Japan’s Minister of Land, Infrastructure, Transport and Tourism.

  • Architectural Interlayer film

    Interlayer films for architectural use made by multi-layer molding have greatly improved noise-reduction properties, and are excellent for decorative purposes.

  • Material for underground water storage systems (CROSS WAVE)

    It is buried underground to store rainwater. With its revolutionary efficiency in storing water, having a void ratio of 93%, it contributes to controlling the flow of rainwater and its effective use.

TECHNOLOGY

  • Materials | Functional ResinDesign of Fire Protection Material

    By aligning thermally expandable graphite when molding, it expands in the direction of thickness. This gives the maximum heat insulation.

  • Materials | Functional ResinChlorinated PVC (C-PVC)

    C-PVC is PVC with chlorine added. It is produced using SEKISUI CHEMICAL’s own PVC polymer and chlorination technology. C-PVC of excellent quality is used in our compounds.
