We develop and sell special organic chemicals for various rubber compounds by utilizing our organic synthesis technologies, including hydrazine derivatives. In particular, we sell special organic chemicals that can improve the fuel efficiency and durability of automobile tires. Tires are important components that contribute to vehicle safety, environmental friendliness, and comfort. The performance of these tires is largely dependent on the properties of the rubber materials used. The world's first original compounds developed by Otsuka Chemical are used in rubber materials for high-performance tires. These compounds are present in trace amounts in rubber materials, so they are by no means conspicuous, but they make a significant contribution to today's mobility society. In particular, the chemical technology used in fuel-efficient tires, which improves the fuel efficiency of cars, contributes to the reduction of environmental impact, which also leads to the reduction of global carbon dioxide emissions.

DENTALL" is a white conductive filler consisting of a transparent conductive layer of nano-order uniformly coated on the surface of a derivative of white potassium titanate fiber (TISMO).
It can be added to various paints, adhesives, films, and molded resin products to impart conductivity without loss of whiteness.
UNIFOAM AZ is the generic name for organic thermal decomposition type foaming agents based on azodicarbonamide. It forms bubbles (cells) in resins, contributing to functionality and weight reduction. It is a derivative of hydrazine hydroxide and has a high level of quality through integrated production from the raw material hydrazine hydroxide.
Unifoam AZ Ultra is a solidifying, cohesive, dust-preventive blowing agent developed based on powder engineering and Otsuka Chemical's proprietary surface treatment technology. Unifoam AZ Ultra has the same characteristics as Unifoam AZ, while simultaneously achieving solidification and dust prevention.
This is a blend-type blowing agentthat contributes to imparting desired functions to plastics and rubbers for which processing conditions are not compatible with conventional azodicarbonamide alone.
It is a state-of-the-art composite material with high dielectric constant and low dielectric loss tangent due to strict control of dielectric properties.
It is used as a latent curing agent for epoxies used in the fields of paints and adhesives, and as a cross-linking agent for acrylic emulsions containing ketone groups. The physical properties after curing can be controlled by the hydrazide compound used. In addition, the reducing performance of hydrazine allows it to be used as a metal reducing and chelating agent in semiconductor and other applications.
Otsuka Chemical's various aromatic compounds are a group of compounds that are expected to have a wide variety of applications in the industrial field of fine chemicals, such as raw materials for pharmaceuticals and agrochemicals, functional polymers, and polymer additives.
These thermoplastic materials meet customer needs, from applications requiring micro reinforcement, such as LED reflector parts and camera module parts, to applications requiring high strength and high sliding properties, such as automotive bearing parts.
This 3D printer filament features high dimensional accuracy and precision moldability and is capable of molding functional parts such as robots. It is a filament material that meets the needs of 3D printer users, enabling the modeling of actual parts such as process transfer trays, gears for reduction gears, and mechanical parts, in addition to prototypes and production jigs.
By compositing special scale-shaped "filler" with thermoplastic resin, this composite material for thermoplastic film combines a low coefficient of linear expansion and high rigidity, and is recyclable.
Maltol and ethyl maltol are pyrone derivatives with a sweet aromatic odor similar to caramel. Since their release by Otsuka Chemical in 1977, they have been widely used by users as synthetic flavorings for food additives. In addition to synthetic flavoring agents, levulinic acid has recently been used as a hair care ingredient, and we are striving to maintain the quality of life of our customers.
We provide high-performance, high-purity electrolytes for capacitors based on our Nitrogen Chemistry and pharmaceutical manufacturing technologies cultivated in the hydrazine business. Our quality control by precise analysis and in-house performance evaluation facilities contribute to the high performance of electric double layer capacitors (EDLC).
Reactive UV absorbing RUVA-93 easily polymerizes with nyl monomers such as styrene, acryl, acrylonitrile, etc., and UV absorbing functional groups can be incorporated into the polymer chain.
Otsuka Chemical provides the SHADAN series of anticorrosive rust inhibitors for internal combustion engine cooling water manufactured using its unique optimal formulas. The SHADAN series of products are available as an anticorrosive rust inhibitors for use in general environments and also as non-freezing anticorrosive rust inhibitors for cold areas.
We propose optimal products for different environments and purposes.
Using even just one of our powerful FR series of detergents makes it possible to remove things that inhibit reactions such as slime, scale and rust which occurred in the everyday operation of factories' cooling towers, heat exchangers, scrubbers, screw compressors and other equipment.
The TERPLUS adhesive series contributes to the construction of a uniform network through advanced molecular weight control in the high molecular weight range, and can be applied to various needs such as low contamination, heat resistance, stress relaxation, and elastic modulus control.
TERPLUS, polymerized by the TERP method, a type of living radical polymerization, has a block polymer structure that enables control of the arrangement of components acting on pigment adsorption and dispersant affinity, resulting in strong adsorption on the pigment surface and steric stability through dispersant affinity. As a result, both excellent dispersibility and dispersion stability can be achieved.
