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.

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.

Functional Resin

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.

Functional Resin

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.

Functional Resin

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.

Functional Resin

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.

Functional Resin

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.
Processing

Precision Molding

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.

Functional Thin Film

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.

TECHNOLOGY

Materials

Functional Resin

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.

Microsphere(Fine particles)

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.
Processing

Precision Molding

Multi-layer Extrusion
This technology adds a variety of functions by using different materials to make multi-layer molded films.

Polymer Processing Foundation

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.
