TECHNOLOGY
- Homogeneous Microsphere Synthesis
- High-precision control and of microsphere with less variation help to make liquid crystal displays(LCDs) higher definition and smaller.
- 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.
- Photoactive 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.
- Polyvinyl 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.
- Epoxy 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.
- High-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.
- Adhesive 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.
- High-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.
- Thin 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.

CFRP is a composite material that combines carbon fiber and resin. Due to its light weight and durability, its use in fuselages is expected to reduce the amount of fuel required for flight, as well as CO2 emissions.
We are developing our thermo plastic sheets business globally, mainly in the United States, for use as interior materials for aircraft and automobiles, housing materials for advanced medical equipment, and exterior materials for automobiles and construction machinery.
TECHNOLOGY
- Adhesive Compound Design (Low VOC)
- Our adhesive technologies suppress VOC and smell to achieve less impact on both the environment and humans. We do not use any of the 13 substances designated by the Ministry of Health, Labour and Welfare to be harmful to the human body.
- Themoexpandable Microsphere
- Thermoexpandable microspheres, with independent air bubbles, have the excellent characteristic of being able to control the size of air bubbles through particle selection.
- Multi-layer Extrusion
- This technology adds a variety of functions by using different materials to make multi-layer molded films.
- High-Magnification Foaming
- This is a high-magnification foaming technology, where ultra-thin polypropylene resin is injection molded and expands to more than twice its thickness by the gas pressure within the resin.

Industrial
We supply products created from cutting-edge technologies, such as adhesives, packaging tapes, and plastic containers for use in daily life and throughout society.
PRODUCTS
From houses to restaurants and hotels, these help to create spaces with a Japanese style. Using sophisticated plastics processing technology, the feeling and moisture absorption of soft rush is maintained while achieving high functionality such as durability, safety, and a rich blend of colors. The mats are resistant to mites and mold, and can be used by people with allergies with peace of mind.
We offer High performance containers for medical and industrial fields.
It is widely used in the fields of construction, civil engineering, automobile interiors, and industrial materials for its light weight, heat insulation, cushioning, moldability, impermeability, and durability, among other features. It is particularly useful for saving energy in everyday life as insulation, waterproofing, and anti-condensation material for building equipment and interior/exterior applications.
We offer a wide range of tapes which can be used for various applications depending on the base material. In addition, we also have environmentally friendly products which use fewer resources (by using recycled materials) and reduce waste.
This adhesive is a plastic resin that adheres instantly. It is solid at room temperature but becomes a liquid when heated. It is applied in liquid form. It rapidly cools several seconds after pressure joining, enabling it to function as an adhesive.
This product uses plastic material waste (recycled container materials) and waste plastic. We have minimized our impact on the environment by using 100%* recycled materials. This was made possible by utilizing our original sandwich formation technology that sandwiches the recycled container materials (core layer) with recycled plastic (skin layer). (*Excluding coloring materials)
