Business Activities

Optical films for LCD

Throughout fiscal 2009 our optical business ran smoothly as demand for LCD televisions rebounded greatly as a result of the economic stimulus measures initiated by many countries. Such initiatives included the eco point system in Japan and the introduction of a policy in China which promoted the common place use of household electrical appliances in rural villages. Continuous cost reduction and productivity improvement activities also contributed to our business results.

We were able to respond promptly to the demand for big screen televisions in Japan, Europe and USA and the replacement demands of CRT-based televisions in developing countries. Furthermore, new LCD televisions which load LED (semiconductors called light-emitting diode) backlights were introduced onto the market. These devices have enjoyed popularity due to their slim lines, being lightweight, having a vivid image and low power consumption. Our optical films have and continue to play a part in the popularity of the new LCD's.

Throughout fiscal 2010, we will continue to contribute to innovative 3 dimensional LCD demand through fully utilizing our technological capabilities in the production of optical films.

Transparent conductive film ELECRYSTA™

Throughout fiscal 2009, as demand for mobile devices such as multifunctional smart phones with touch-sensitive panels increased, as did the demand for transparent conductive film ELECRYSTA™ as well as our optical films.

If the LCD market reaches its maturity in the not so distant future, we will pour our energy into further improvements and innovative product development aiming to be a business which produces stable and continued profits.

Thin-film metal base board
with high resolution circuit "CISFLEX®"

Our printed circuit materials, flexible printed circuit "NITOFLEX®" and thin-film metal base board with high resolution circuit "CISFLEX®" performed well with the increase in demand for hard disc drives (HDD) used in personal computers. To date HDD have been loaded onto personal computers, but with the appearance of netbook computers, the external HDD model types have increased in popularity. They have begun to be commonly used for storing a range of visual and media content as a result of the expanding applications for printed circuit materials.

In relation to semiconductor encapsulating materials, the markets throughout fiscal 2009 did not fully recover. Despite this our environment-responsive resin made a mild recovery.

Electronic processing materials ended on a down note, as the materials for semiconductors were affected by customer business investment restraint and the entry of other rival general-purpose products. On the other hand, demand increased for materials used for electronic components on the back of an increase in consumer demand for flat-screen televisions, personal computers, mobile phones and so on. This in turn resulted in the production of our electronic processing materials rebounding.

Toward the future, we will focus our efforts on increasing profits through further the rationalization of existing products and the development of new products in growth fields.

Transparent double-coated
adhesive tapes "LUCIACS®"

Due to the increase in demand for flat-screen televisions, personal computers, HDD and so on in developing countries including China, the sale of surface protective products for optical elements and sealing materials was strong.

Owing to the increase in smart phones with touch panels, the production demand for transparent double-coated adhesive tapes has expanded rapidly. Touch panels are constructed from a laminated body made from several materials, one of which is transparent conductive film. In order to glue together the various elements needed to make a touch screen, transparent double-coated adhesive tapes are used. These films not only fill gaps on the inside of touch panels but also adjust the refractive index of light. Furthermore they contribute towards projecting a more vivid image. In order to respond to the diversifying demands associated with the spread of touch panels, we will aim to strengthen our future product lineup.

Electrical insulating materials
for hybrid cars

With regards to materials produced for the automobile industry, we were able to record strong sales of electrical insulating materials owing to an increase of production of hybrid cars from tax cuts for eco-friendly cars. This occurred despite the decrease in production that took place in the first half of the fiscal year.

As part of our efforts to expand domestic-demand in markets of growing developing countries, we settled on an overseas affiliated company in India in November 2009 and started to construct business models centering on further expanding our tape business. We will look to positively expand our tape business into other developing countries where high growth looks promising. Furthermore, we will continue to promote earth-conscious "manufacturing" as we pour energy into new-product development.

NittoPhase®HL

Throughout fiscal 2009, many people were frugal with their usage of drugs and medicines. The Nitto Denko Group's transdermal clonidine drug delivery patches (for hypertension) received USA authorization and were launched onto the market and have achieved healthy sales results. Currently, there are eight items using transdermal drug delivery patch technology on sale throughout Japan and USA. We aim to increase the range of transdermal drug delivery patch products whilst at the same time driving expanded global sales of transdermal drug delivery patch products and further enhancing product development in developing countries including China.

In China, our tulobuterol patch (drug for asthma) is being sold after gaining import approval. Further efforts will be targeted toward strategies aimed at increasing sales.

Our medical business is closely linked to "Fine" which is one of our three key values in developing new business areas. The three values are; "Green (contribution to global environment), Clean (support for new energy) and Fine (life science)". In order for us to further expand our business in the medical arena beyond the production of transdermal drug delivery patches, we aim to make steady progress in the biomedical field using our core polymer synthesis and processing technology. An example of the way we have applied biomedical technology relates to the field of nucleic-acid drugs. These drugs will hopefully prove to become the cure for many diseases. Our USA subsidiaries, Nitto Denko Technical Corporation and Kinovate Life Sciences Inc. have developed a solid polymer support "NittoPhase®HL" for oligonucleotide synthesis and have launched its sale. Continued research on biodegradable polymers useful in molecular-targeted therapy will be conducted. Molecular-targeted therapy is a treatment which delivers drugs to targeted parts of the body.

We hope to minimize patient discomfort and in doing so the discomfort experienced by families through our products which have been developed through utilizing technologies accumulated through transdermal drug delivery patches and our advanced polymer synthesis and processing technologies.
