Examples of Denka Group Solutions That Address SDG-Relevant Social Issues

"QuickNaviTM-Flu" Accumulating Applied Antigen/Antibody Reaction Technologies over the Course of Our Diagnostic Reagent BusinessGOOD HEATH AND WELL-BEING

Social Issues

On the back of growing public concern about infl uenza pandemics, frontline medical practitioners are called upon to initiate the appropriate treatment of infl uenza patients at the earlier stages of disease development. Accordingly, they are in need of technologies that help them render quick and accurate diagnosis of infl uenza virus infection.

"Spherical Alumina and Thermally Conductive Spacer"
Contributing to the Development of Batteries for EVs

Social Issues

In an effort to reduce emissions of automotive exhaust gas, which has a negative effect on the environment, the use of HEVs, PHEVs and EVs*1 is being actively promoted. At the same time, manufacturers are facing growing demand for solutions that enhance the energy efficiency*2 of these vehicles.
Although lithium ion batteries (LiBs) are seen as one of the most promising power sources, these batteries generate heat when they are activated. While heat deteriorates batteries’ performance and their energy efficiency,
overheating can lead to them erupting into flames. Thus, countermeasures against heating have become essential to producing automotive LiBs for practical use.

Thermally conductive sheets and spacers

The Denka Group’s Technological Solutions (source of value and product technologies)

Denka handles a range of composites consisting of SiO2, Al2O3, Si3N4, BN and AlN as well as other heat-conducting fi llers that support the Company’s key thermal conductive technologies and are used in combination of organic materials. Because of this, the Company is well-positioned to supply optimal fi llers or composites capable of satisfying customer needs. Among those products, Denka’s spherical alumina, which boasts superior heat conductivity,
is used in a variety of heat dissipating products. This strong seller is thanks to the Company’s proprietary technologies for shaping alumina into the spherical form and producing composite materials with various diameters. Also, Denka’s thermally conductive spacer, made incorporating silicon resin, signifi cantly enhances the cooling efficiency of lithium ion batteries when it is inserted into the gap between a heat-generating battery component and a cooling component. This product has thus become an integral part of lithium ion battery cooling systems.

"CO2-SUICOM" Helping to Reduce CO2 Emissions through the Supply of Low Environmental Footprint Concrete

Social Issues

Emissions from the cement and concrete industry presently account for around 4% of total industrial CO2 emissions. Cement manufacturers are thus facing an urgent need to develop low environmental footprint products. Accordingly, technological development is focusing on utilizing raw materials with smaller CO2 emissions intensities (e.g., steel slag, fly ash and special cement additives) during processing.

CO2 - SUICOM

An environment-friendly concrete, CO2-SUICOM contributes to CO2 reduction in the course of cement manufacturing and throughout its product life cycle. Incorporating a special cement additive made using slaked lime—a byproduct of the acetylene gas generation process—that works to harden concrete through carbonization, this concrete absorbs CO2 during production, resulting in a product with a zero or even negative lifetime CO2 emissions intensity.

DENKA Thermosheet Special BOPS “Mighty Guard”
Contributing to Food Safety and Enhanced User Convenience

Social Issues

On the back of the aging of society and an increase in the number of two-income households, there is a growing demand for hassle-free food products that satisfy the needs of families that rarely eat together. Moreover, take-out food, which is usually microwaved before consumption, has risen in popularity and has come to encompass an increasingly broad range of cuisines. Because of this, makers of food containers are being asked to develop containers with superior heat and oil resistance to help ensure food safety. Furthermore, growing concerns about environmental issues are prompting these producers to place greater emphasis on contributing to resource saving and CO2 reduction by creating lightweight containers with superior strength.

Mighty Guard

Denka boasts a robust R&D structure enabling the development of highlyfunctional food packaging sheets even from the raw material stages. This structure allows the Company to employ a variety of ingredients and create high-value-added sheets boasting diverse characteristics. One example is BOPS, a special heat-resistant sheet that can stand up to heating in an industrial microwave oven. This product is used as a material for food containers supplied to convenience stores, thereby helping to enrich the diets of the growing number of solitary diners.
In addition, Mighty Guard is a new product boasting signifi cantly improved oil resistance. Overcoming the typical weakness of plastic food containers, Mighty Guard helps enhance consumer convenience as it makes it possible to microwave a wide range of food without removing the packaging.

"DENKA COAT" Facilitating the Restoration of Damaged Ground and the Development of Natural Greenery

Social Issues

In recent years, businesses engaged in such civil engineering projects as the construction of expressways and dams, the development of housing plots and the establishment of industrial facilities are being called on to ensure that the environment in communities surrounding project areas remains undisturbed.
Also, when roads and riverbanks are damaged by heavy rainfalls, earthquakes or other natural disasters, there is often an urgent need to restore these sites to protect a municipality and, in particular, to harden the soil around the sites to prevent catastrophic soil erosion. Moreover, the hardened soil is usually expected to be capable of supporting greenery.

DENKA COAT is a soil erosion prevention agent based on a synthetic resin emulsion and is specialized for the development of greenery and the prevention of soil erosion on a slope. With its lineup encompassing liquid and powder types, DENKA COAT boasts superior water-retention and is capable of rapidly forming a layer that is hard yet air permeable. Thanks to these features, this product serves as a key solution to prevent massive soil erosion attributable to rainfalls and earthquakes. Furthermore, it is completely free of endocrine disruption chemicals and harmful heavy metals, refl ecting the due consideration given to environmental concerns from the product design stage.
