Development of Novel material contributing to Environmental Purification using Natural Energy
Showa Titanium Co., Ltd., subsidiary of Showa Denko (SDK) has announced the development of titanium oxide fine particles for use in UV-light-responsive photo catalyst with high level of activity. When exposed to UV light titanium oxides causes strong oxidation /reduction reaction helping to decompose stains from organic substances. It also exhibits ultra hydrophilicity causing water to spread as a thin film, making the titanium oxide based photo catalyst an ideal product for environmental purification using only natural energy in such applications as antifogging window glass and antifouling coating for external walls.

Showa Denko (SDK) has successfully developed printable conductive inks for manufacturing electronic devices, providing silver nanowire as well as copper/silver hybrid type inks. The ink has been jointly developed with professor Katsuaki Suganuma of Osaka University. By combining the newly developed ink with Photonic Curing process, highly stable transparent conductive patterns can be formed on flexible films. Read more
Development of Hybrid Type System for Decomposing PFC
PFCs (Perfluoro Compounds) are used in the process of etching LCD panels and semiconductors and they need to be decomposed before exhaust due to their high levels of global warming potential. The current available system requires PFCs to be decomposed by means of catalyst where the resulting fluorine-containing substances are obsorbed into water, whereby the system needs after waste water treatment. In order to remedy this issue, SDK has developed a dry-type process for removing fluorine containing substances under the catalytic decomposition system through introduction of low cost calcium based absorbent.

Production of Biodegradable Plastic for Consumer Goods Packaging by SDK
Showa Denko K.K. (SDK) has announced the production of bio-based biodegradable polyester resin Bionolle™ using bio-derived succinic acid. The new Bionolle can be completely decomposed after use into water and carbon dioxide, where it has been used in compost bags as well as mulch films. Read more
Development of a New LED-Based Cultivation Method for Increase the Amount of Harvest
Show Denko K.K. (SDK) and Yamaguchi University have jointly developed a LED-based cultivation method for plant growth facilities, which significantly shortens the shipment cycle while increasing the amount of harvest through the irradiation of light which has been optimized for plant growth. The choice of Led lighting is mainly due to its narrow wavelength range enabling selective irradiation of light with suitable wavelengths resulting in efficient cultivation of plants. SDK has developed a specialized LED chips capable of emitting red light with wavelength of 660 nm, with highest luminous efficiency in the world according to SDK. Read more
Release of World’s Highest Capacity 2.5-Inch HD Media Disk by SDK
SDK has announced the commercial shipment of 2.5-inch hard disk (HD) media with industry’s highest capacity of 500 gigabytes per disk. The new disk utilizes the 6th generation perpendicular magnetic recording (PMR) technology, resulting in dramatic increase in recording density. The new product was developed as demand for high capacity HD media is on rise for such applications as PCs, Cloud computing as well as digital electric appliances. Read more
Development of a New Heat-Resistant Transparent Film by SDK
SDK has made an announcement on development of new heat-resistant transparent film for use in displays. The newly developed “SHORAYAL™” transparent film was produced based on company’s proprietary resin technology for glass lens applications. The “SHORAYAL™” features a high transparency and high heat resistance, which allows it to be used at high temperature processes of up to 250 degrees Celsius. Read more
Introducing the Carbon-Coated Aluminum Foils for Lithium Ion Battery by SDK
Showa Denko K.K. (SDK) and Showa Denko Packaging Co (SPA) has announced the volume production of carbon-coated aluminum foils capable of reducing electrical resistance of lithium-ion battery (LIB) electrodes, resulting in substantial improvement in quick charge/discharge performance, a requirement for collectors in automotive LIBs. The new aluminum foils with the trade name of SDX ™ can reduce the contact resistance by around 50% in comparison with conventional plain aluminum foils. SDX has been manufactured through coating plain aluminum foils with electrically conductive carbon, using company’s proprietary technology. Read more
Production of Environmentally Friendly High Purity COF2 Gas for manufacturing LCD Panels by SDK
High-purity fluoride gases are used in etching thin oxide/nitride films in production of LCD panels. The COF2 (Carbonyl Fluoride) for example decomposes by way of hydrolysis into hydrogen fluoride (HF) which is easy to dispose of in comparison to typically used nitrogen trifluoride (NF3) and SF6, resulting in reduction in disposal cost and less environmental impact. Up to now, use of COF2 has been very limited due to its purification related problems as well as its high cost. Read more
Full-Scale Launch of New Curing Agent for use in UV-curing Resin and Epoxy resin in Paints, coating and adhesives by SDK
Show Denko KK (SDK) has announced the full-scale launch of new functional monomer for paints, coating, and adhesives. In order to achieve the curing of UV-curing resins, the company has increased the amount of polymerization initiators, and in case of epoxy resins, the temperature has been increased. The newly developed Karenz MT™ PE1 the curing rate has substantially been improved, resulting in reduction of the amount of energy required for production and processing as well as improvement in adhesiveness and elongation.
