SAKAI CHEMICAL GROUP'S TECHNOLOGICAL STRENGTH
We are responding to the needs of an increasingly sophisticated society using our three core technologies.
Powder processing technology, which imparts advanced functions to inorganic compounds; organic synthesis technology, where a unique technology cultivated through the development from inorganic to organic materials is rooted in the organic field; and pharmaceutical manufacturing technology that meets various needs in the medical and health care fields.Various products produced by these three core technologies contribute widely to society.
01
Powder Processing Technology
Ultra-microparticulation
To meet the needs of cutting-edge fields such as electronic material components, which are becoming increasingly miniaturized, we have established the technology to manufacture nano-level ultrafine particles through proprietary processes such as the hydrothermal method.
Particle shape control
We have the technology to freely control the particle growth process.The stable production and supply of powders in various shapes, such as columnar, plate, needle, and petal, enable high functionality in product applications.
Surface treatments
By coating powder surfaces with different types of compounds, we develop powder products with a variety of special functions, including suppression of activation, agglomeration prevention, and improved dispersion and stability.
Purification
We have the technology for strongly purifying a wide variety of organic and inorganic compounds, utilizing the advanced crystallization technologies and proprietary manufacturing know-how we have cultivated over many years.
For example, in the following applications
For electronic components
Laminated ceramic capacitors, indispensable for electronic devices, have been downsized to 0.25 x 0.125 mm.
For achieving this, high-purity and ultra-fine dielectric powders are used as materials to produce dielectric layers as thin as 0.1 μm.
* 1 μm (micrometer) = 0.001 mm (millimeter)
For cosmetics
Zinc oxide is used in sunscreens, etc. to block UV rays.The use of shape control technology to form the particles into a hexagonal plate shape enables the creation of high-quality products such as foundations that conform easily to the skin and spread easily.
For paint
Titanium dioxide, used as a pigment in paints, has a strong oxidizing effect and decomposes organic matter when exposed to ultraviolet rays, but coating the surface of the powder with an inorganic substance eliminates this activity and enhances the stability of the paint product.
For fibers and various coating materials
The antibacterial and antiviral effects of zinc oxide, our traditional business, support comfortable living by helping improve the sanitary functions of textiles and various coating materials.
02
Organic Synthesis Technology
Organic Sulfur Compounds
We develop and manufacture a variety of organic sulfur compounds as materials for resin products that are indispensable in people's lives, including optical and electronic materials.In particular, β-mercaptopropionic acid, a raw material used in plastic lenses with a high refractive index, is a special product manufactured by only two companies in the world and is proof of the Group's advanced technological capabilities.
Organic Phosphorous Compounds
In the field of organic phosphorus compounds as well, we have developed and supplied a wide variety of products to industry, including extreme pressure agents for lubricating oils, antioxidants to prevent degradation of plastics, flame retardants for improving fire resistance, dispersants, and catalysts.We are also conducting research aimed at expanding into new fields by applying the advanced synthesis technologies we have cultivated.
For example, in the following applications
For eyeglasses
Blending organic sulfur compounds to increase the refractive index of plastics enables glasses with strong lenses to be made thinner and lighter,
enhancing their functionality and fashionability.
For powered machinery
Organic phosphorus compounds are added to lubricating oil, which is essential for various powered machinery, including engines.
They form a film that prevents burning, enabling stable operation even at high temperatures.
03
Pharmaceutical Manufacturing Technology
Barium salts
The Sakai Chemical Group's expertise in synthesizing barium salts also plays a part in the field of pharmaceuticals.We are proud to hold the top share of the domestic market for X-ray contrast media used in radiography.Our ability to freely control the composition, size, and shape of the particles of the inorganic powder barium sulfate enables us to provide a wide variety of products that meet the needs of medical applications.
GMP compliance
Using our state-of-the-art synthesis technology and manufacturing facilities, we research, develop, and manufacture a variety of pharmaceuticals, active pharmaceutical ingredients, and intermediates.Our research department responds to customers' high-level requests, ranging from compound root searches to sample synthesis, manufacturing methods, and industrialization.We handle production with a thorough quality control system that complies with Good Manufacturing Practice (GMP) standards.
For example, in the following applications
For prescription pharmaceuticals
We provide X-ray contrast media, gastrointestinal drugs, and various other medical diagnosis support devices.
We support the forefront of ever-evolving medical care with our safe, high-quality products and quick response with integrated manufacturing and sales.
For general over-the-counter drugs
We offer a broad lineup of over-the-counter drugs, including the cold remedy "Kaigen," as well as specific health foods.
We support health promotion in the age of self-medication.
