| Development of SHINKOLITE (ACRYLITE)
MR 0.8 mm grade |
 |
| Cellular phone panels |
SHINKOLITE (ACRYLITE) MR is an acrylic resin
sheet given a hard coating using our proprietary technology.
Sales of the product have been increasing, primarily for use
in cellular phone panels. While these applications have mainly
involved products with a thickness of 1.0-1.5 mm, the miniaturization
of cellular phones has created a demand for even thinner sheets.
We have made further improvements to our continuous sheet
production technology, enabling the manufacture of a 0.8-mm
grade. This technology has given cellular phone manufacturers
greater freedom of design, and we expect this grade to assume
a dominant position in this field. |
| Development of scratch-resistant hard-coat
materials for optical disks and flat panel displays |
| Because photocurable paints
are highly functional paints consuming fewer resources and
less energy, they have continued to show strong growth in
such fields as automobile parts, IT equipment parts, containers
and coatings for resists. We have developed and brought to
market RAYQUEEN, a hard-coat material that satisfies the market
demand for coatings with an even higher level of scratch resistance.
RAYQUEEN is an organic-inorganic hybridized superhard coating
material comprising nanosize inorganic particles that are
surface treated using our proprietary technology. Because
the inorganic microparticles form a strong crosslinked structure
with the organic component, these results in a novel hard-coat
material providing a variety of functions unattainable with
conventional materials, including excellent weather resistance
and contamination resistance, in addition to scratch resistance
and endurance. Market evaluation of the product is high. |

| Expanded use in automobiles of environmentally
friendly acrylic powder for acrylic sol |
| Because of the burden placed
on the environment by vinyl chloride resins, we have developed
alternative, environmentally friendly materials, manufacturing
and marketing the DIANAL LP series of acrylic powders
for sols. To meet growing customer demand, we increased the production
capabilities of the Otake Production Center to enable it to
produce 15,000 tons annually, and the plant has been operating
smoothly since inception of production in July 2003. The acrylic
powder is a highly functional product that, by combining mutual
solubility/insolubility with a plasticizer, has achieved an
excellent balance of storage stability in a plasticizer, plasticizer
retaining ability in a gelled film, and film forming ability.
Further, in addition to improving the physical properties
of the sol, we have also improved the handleability of the
powder by causing cohesion of primary particles into easily
collapsible secondary powders.
At present, acryl powders are primarily considered to be very suitable for use
in automobile undercoats. However, we are developing resins which exhibit good
flexibility and storage stability even when non-phthalate ester molding agents
are used. Also, we are expanding applications of materials without vinyl chloride
and without phthalates, such as sol inks. |

| Development of METABLEN S2100, modifier for
impact resistance, giving plastics superior external appearance and
clear color. |
In order to improve mechanical strength,
METABLEN Series S, C, E, and W, modifiers for impact resistance
are added. Recently, in order to meet the varied needs of our customers
with regard to design and appearance, modifiers for impact resistance
that produce vivid colors has been desired.
Mitsubishi Rayon has made the best use of unique
polymerization, formulation and morphology control technology for
silicon rubber to develop METABLEN S2100, silicon based modifier for
impact resistance giving plastics both superior impact strength and
clear color, which has enjoyed good sales. |
| Development of POF (Plastic Optical
Fibers) for onboard LAN |
 |
| POF cable |
We have developed novel cables as POF cables
for onboard LAN. Our POF has reduced loss from sharp bending
and improved long-term reliability. As a result, the cables
can be used in narrow spaces into which they are inserted
with a small curvature radius and are suitable for applications
involving severe humidity and heat-related conditions, allowing
for a greater freedom in installing the cables in automobiles.
The key points in this development
include POF structure design, development of novel materials
suitable for POF filaments and POF cords, and research of
optimum manufacturing conditions for increasing transmission
characteristics and mechanical properties. We have put to
use over 30 years of POF design and development expertise
to achieve this product. |
| Development of an optical fault detection device for optical films and optical glass |
 |
| an optical fault detection device |
We have developed an optical fault detection device for optical films
and optical glass, the Eska Optical Tester Lighting Unit Table. This
table with a lighting unit comprising a light source and a special plastic
optical fiber light guide amplifies the luminance of specific defects
in various types of optical film and glass such as small scratches,
surface unevenness, spots, foreign substances, and stains, making them
easier for the inspector to find. It was exhibited in the 16 th Flat
Panel Display R&D/Manufacturing Technology Show held at the Tokyo
Big Site convention center on April 19-21, 2006, and has received many
inquiries from users. |
| Development of plate lenses |
 |
| plate lenses |
Rodlens is a cylindrical gradient-index rod lens, comprising an optical fiber cut to a specific length and having a refractive index gradient in the radical direction.
This lens produces an erect same size and actual object image.
This RODLENS ,
the first such plastic lens developed in the world, can be lined up side-by-side
to form an array which can be used in the image-pickup devices of such
commercial products as fax machines, multi-use printers, and scanners.
We have recently developed Platelens, consisting of several RODLENS lined
up two-dimensionally to form a plate. Platelens is distinctive in that
it can make the image at the lower part of the lens appear to stand out
three dimensionally. We expect that this lens will be installed
as display elements of instruments for the most advanced engineering fields,
such as information processing technology, automobiles, and medical treatment
devices, in the future. Through our R&D we have combined the technology
we have nurtured in our development of plastic optical fibers and our
exclusive refraction gradient formation technology to achieve the highest
possible resolution and a lineup of products expanded to meet all applications. |

| Development of high-luminosity Y-type
prism sheets |
 |
| Thin shape quantity luminosity
prism sheet (M168Y-S) for mobile computer |
We have developed Y-type prism sheets (M268Y-K,
M168Y-S), a high-luminosity grade of total-reflection prism
sheets. We have accomplished successful development of the
Y-type prism sheets by bringing together our optical design
technology, precision mold processing technology, and precision
shaping technology. Compared with earlier products, luminosity
has increased as much as 30%, and users have given these sheets
high praise.
M268Y-K is a prism sheet mainly developed
for notebook PCs, and M168Y-S is a prism sheet developed for
the small backlight systems for mobile devices. The prism
pitch (18µm) of the M168Y-S is less than that of the M268Y-K,
allowing for thin design. |
| Development of high-luminosity waveguide
plates for total reflection type backlight systems |
| We have developed and brought
to market waveguide plates for backlight systems for 15-inch
notebook PCs that are designed for optimal use in total-reflection
prism sheets. Using these plates in combination with the above-mentioned
Y-type prism sheets creates a backlight system with unprecedented
high luminosity. |
| Development of the world's only core-in-sheath
composite spinning technology with wet-spun acrylic yarn |
| We have developed the world's only
core-in-sheath composite spinning technology with wet-spun acrylic
yarn. This composite yarn is named Corebrid™ , and the Corebrid Series
we have developed includes Corebrid Lumo™ incorporating a temperature
stabilizing polymer in the core, Corebrid Elequil™ in which
a fine white conduction powder is dispersed to suppress static electricity,
Corebrid Thermocatch™ in which light-absorbing white powder is dispersed
to covert light energy into heat, and Corebrid Propearl™ in which
acetate is added to provide suitable moisture absorption and odor extinguishing
capability. |
| Development of VENTCOOL fibers, triace/diace
conjugate fibers that contract or expand under the effect
of moisture and automatically adjust air permeability in clothing;
application of such fibers for sportswear and innerwear materials |
Acetates can be of two types:
diacetates and triacetates. If raw materials of those two
types are integrated into one thread by a method called composite
spinning, then only the diacetate portion of the thread will
effectively absorb water and will be chemically converted
into cellulose, which expands if water is absorbed. Because
triacetate does not absorb water, this difference in properties
causes spring-like twisting which results in contraction or
expansion.
If knit products using
such fibers are worn, when a person perspires because of heat,
the moisture is sensed (absorbed) and the thread expands,
causing meshes in the product to expand and improving air
permeability, thus creating a refreshing feeling. When the
perspiration dries, the meshes again become closed and warmth-retaining
ability is increased. The yarns thus act as a breathing human
skin. "Senken Shinbun" (March 29, 2004). |

| Various improvements to A.H.Y. suitable
for cationic dyeing under normal pressure; investment and
expanded sales in the field of materials to replace rayon,
such as lace curtains or inner lace |
A.H.Y., polyester
filaments suitable for cationic dyeing under normal pressure,
is a material with a long history, as almost 20 years have
passed since they first appeared on the market in 1984. It
rose to prominence due to changes in the environment. This
was because, 1 Kuraray Co. and Asahi Chemical Co. withdrew
from production of rayon filaments, and the suitability of
A.H.Y. as a rayon replacement was confirmed;
2 as compounding with materials became commonplace, there
was greater demand for materials suitable for dyeing at normal
temperature and under normal pressure; and 3 in addition to
excellent dyeability, A.H.Y. has a low Young's
modulus (half that of regular polyesters) providing for unique
softness and flexibility.
Further,
within last two years, A.H.Y. has been further improved and
its application, primarily as a replacement for rayon, has
expanded. Thus, these filaments are now employed for easily
dyeable yarns, lightweight yarns, self-stretching yarns, ultrahigh-gloss
yarns, Y-section yarns (absorbed moisture can be dried at
a high rate), hollow yarns (lightweight), full-dull yarns,
and light-storing yarns, and are also used in POY and in consignment
production of staple fibers for other companies. Main applications
include apparel and ornaments, lace curtains, inner lace,
bathing suits, fabric for clothing, and sweaters. "Sen'i
News" (March 7, 2004). |

| Development of new raw yarn for carpets, Pylen |
| For our polypropylene filament yarn PYLEN we have developed a variety of new raw yarns for carpets.
Our variable contraction mixed yarn POLYPHONY contributes to
excellent carpet appearance and has a soft texture and good erectness
under pressure, and our Arupoto yarn which has excellent bundling properties
due to unique heat setting behavior caused by the lightness and distinctive
shape of the yarn with three hollow central spaces that take up much
of the cross section area are used in optional car floor mats etc.
Recently, we have developed a new raw yarn mixing flattened cross section
yarn with conventional Y-section yarn. The flattened yarn contributes
to excellent outer appearance and a soft texture, and is suitable for
use in the home as well as in the car. |

Development of carbon fiber composite materials for commercial
airplanes |
 |
| Airbus |
Composite materials for airplanes, in contrast
with composite materials for sporting goods such as tennis
rackets and golf shafts, must have excellent heat resistance,
impact resistance, and resistance to moisture in order to
ensure structural reliability of the airplane.
Using
the expertise that we have accumulated over many years in
applications for commercial airplanes, we have successfully
improved the main physical properties of carbon fibers, interface
characteristics of carbon fibers and resins, and properties
of resins used in composites, and thus have developed technology
for the fabrication of composite materials meeting the requirements
of airplane applications. The development of this technology
has made us a manufacturer of materials supplied for Airbus
Co. and we expect there will be growing demand for airplane
applications. |

| Solaris, a sunlight tracking and collecting system |
The ecology system Solaris utilizes
natural energy sources to the maximum extent by automatically tracking
the sun with a high performance light sensor and collecting sunlight.
The sun tracking device keeps the sunlight at the same angle, for efficient
light collection. A large light collection surface is realized through
concurrent use of a mirror and a prism sheet. Through an optical diffusion
device using a Fresnel lens, the range of incident light can be adjusted.
Further, use of solar batteries makes an external electric supply completely
unnecessary. |
| Development of the sophisticated surfacing process Clearlight, allowing high transparency, stain prevention, anti-refrection, and electromagnetic wave prevention through thin film processing of plastic surfaces |
Using our exclusive resin surface improvement technology, we have
developed this sophisticated product which combines functions for
anti-refrection, electromagnetic wave prevention, reflection
reinforcement, and multi-halfcoat. It has comes in [CL] grade for coating
production methods, [CLV] grade for vacuum deposition methods, and
also [GLG] grade for press production methods.
This product is suited for applications in such fields as medical
treatment, devices installed in cars, and digital monitors, where
demands for high resolution, high luminosity, and large size are increasing. |
| Development and start of sales of DNA chips
for analysis of micro RNA, GENOPAL MICH and GENOPAL MICM |
we have developed a DNA chip for micro RNA analysis.
Micro RNA are small functional RNA molecules which do not code proteins but have specific roles with regard to vital functions, such as controlling gene expression, aiding in organism growth and cell differentiation and propagation.
They have also been found to play a role in various diseases, and these new functions are drawing attention recently.
Mitsubishi Rayon started development of a DNA chip for analysis
of micro RNA at an early date, and has completed a micro RNA analysis
DNA chip exploiting the features of our GENOPAL â . This DNA
chip should contribute to R&D of new micro RNA.
GENOPAL â for applications other than micro RNA analysis are
now being developed, entering into the health care, environment, and
foods fields. |
