Rubber materials constitute the core of the materials used in our products. Rubber material technologies include mixing design technique for providing required performance and functions, mixing technique for materializing the performance and functions of rubber materials in accordance with the compound design, and processing technique for molding the resulting rubber compound. We have been improving and developing these techniques all through our history. In addition, rubber material evaluation technology is indispensable for product development. We improve not only the evaluation techniques defined in standards but also our proprietary evaluation techniques to continue the improvement and acquisition in order to attain the performance required by our customers.

Our representative resin product, "Mulite," is a distinctive product that uses our proprietary compound design technique as with rubber materials. We have been improving material and product evaluation techniques in addition to processing techniques centering around compound designs and mixing techniques, injection molding, extrusion molding, and calendar molding for materializing intended performance. We continue to accumulate and improve product development to answer the needs of our customers.

Urethane products, as typified by "Bancollan," are greatly influenced by the polymer molecules in the materials. Hence, in addition to our proprietary compound design technique that is similarly important for rubber and resin materials, polymer design is also an important technology for urethane materials. Urethane materials are widely different from rubber and resin materials in processing techniques. They are molded through dispersion and mixing of multi-component liquid materials typically using casting machines. Urethane material products are often used in electronic devices. So we have been accumulating and improving evaluation techniques in different fields as well.

Most of our products are made by combining metal, fiber, and resin with rubber or urethane, instead of making them only with rubber or urethane. Bonding technology is essential for compounding of these materials. It decides the performance of compound products consisting of various materials. Our representative products, power transmission belts and conveyor belts, use fiber materials. The bonding technique with rubber is a key to the performance of these products. We have also been accumulating and improving the processing technique and evaluation technique used in bonding.

Nanoparticle creation technology is one of the latest core technologies we have developed for new product development using metal nanoparticle conductive materials and nanocarbon functional materials. It is an extension of the dispersion technology of rubber materials and resin materials. For example, nanoparticles have a characteristic effect, called nano size effect, in which metal nanoparticles with sizes of several nanometers to several tens of nanometers fuse at temperatures ranging from room temperature to over 100°C, which is a far lower melting temperature than that of solid metals. In order to maximize this effect, nanoparticles need to be maintained in a dispersed condition for a long time. It is the result of our technological development focusing on dispersion techniques that our metal nanoparticles can fuse at such low temperatures.
