We manufacture and sell bentonite-based products for castings, civil engineering and construction, and toilet sand for pets, procure and supply mud conditioning materials, and conduct various studies and analyses related to bentonite.
Casting molds used to cast metals into automobile or industrial machine parts are made by molding sand containing bentonite as the caking additive into desired forms. Casting molds are highly productive and used widely for making castings.
We not only sell bentonite products but also support customers in building optimum production environments. Working together with our laboratory that analyzes casting sand, we serve customers' various needs and provide our own total engineering services.
Civil engineering and construction field
In drilling by the earth drill method or other methods in pile foundation works, drilling mud using bentonite is used to form a coat on the borehole walls in order to prevent their collapse due to water infiltration. Soil mixed with bentonite with seepage control performance is used for seepage control in general waste disposal sites. KUNISEAL and KUNISHEET are also used mainly as waterproof materials in underground structures.
Also in radiation-contaminated waste disposal sites, environmentally friendly, cost-effective bentonite is used. The clay is also used in boring for geothermal power generation, a renewable energy source, or extraction of seabed resources.
Pet products field
One of the most popular bentonite products is toilet sand for pets that takes advantage of the clay's high water-absorption effect and caking property to solidify excrement of pets for easy disposal.
Bentonite-based toilet sand products for pets are available in different types, including a large pellet type that significantly reduces scattering of sand and stirring up of dust, a cost-effective crushed type, and a granular type that is the closest to natural sand and solidifies into small lumps.
We not only process agrochemicals but also manufacture, process, and sell agrochemical bases, raw materials for processing agrochemicals and other agrochemical-related materials, and livestock feed.
Originally, we were dealing in bentonite-based products made by impregnating granular bentonite with active ingredients of agrochemicals to control the speed and amount of their release.
Recently, with the advancement in development of active ingredients and agrochemical delivery systems, use of bentonite has declined. However, based on our superior formulation technology, we process agrochemicals that take advantage of technologies for controlling the speed and amount of active ingredient release for agrochemical manufacturers inside and outside japan.
Chemical Products Business
We manufacture and sell refined bentonite and environmental preservation treatment agents.
Of products in the fine chemicals field, KUNIPIA, which is refined bentonite made by increasing the purity of montmorillonite, the main component of bentonite, has the ability to increase the moisturizing effect, extensibility, and thickening effect of materials mixed with it and thus is used in cosmetics, paints, and other products indispensable in our daily life. SUMECTON, which is transparent, synthetic smectite with high thixotropy, is used in various fields as a thickener or an agent to improve functionality.
Our environmental preservation treatment agents are used in the exhaust gas treatment process in waste incineration plants.
As our production and development site for refined bentonite and other products, the Iwaki Factory & Laboratory has been actively involved in environmental conservation activities, including formulating an “Environmental Policy” based on our management philosophy and acquiring ISO 14001 certification.
