Founded in 1964, for over a half a century,
our company has aimed to manufacture
products that contribute to society byengaging in the production of Masterbatches
that are essential for rubber products used in
automobiles, electric appliances, precision
machinery, construction materials, athletic
footwear and adhesives, as a specializedcompany of rubber Masterbatches.
In particular, our highly sophisticatedproduction system and unique research anddevelopment that explores the possibilities ofrubber as a raw material, with a commitment
to only the best quality etc., and technology
and know-how that we have cultivated over
the years have been highly valued not only
domestically but internationally as well.
The economic environment that surrounds us
and social structures have become increasingly more complicated and we face drasticchanges in association with recent globalization and, accordingly, customer needs havebecome more diversified and sophisticated.
Under such circumstances, under thecorporate philosophy of“Materials Innovation―We create value through materials basedon mixing technology to enrichsociety, people and thee n v i r o n m e n t” W e w i l lcontinue to be involved inthe creation of newtechnology and new value,
striving to contribute toour society.

Productization Our products are found across a range of applications throughout society and in our daily life.
〈Automobile〉

In order to make rubber products, a process for preparing rubber materials having theproperties needed in a rubber product (Masterbatch) is necessary.
However, this process is extremely complicated, as the properties of rubber entirely change
just by a difference in the quantity of raw materials formulated or the kneading method.
Although this is a very difficult field that has yet to see the establishment of an academic
system worldwide, it is our mission to develop and manufacture rubber targeting more
effective use of rubber products, while conducting research on Masterbatch.

We have three plants in Japan, each of which has established a highly sophisticated production system bycombining complete process control and accumulation of know-how in a well-balanced approach.
Each of the plants is engaged in the production of high-quality products for meeting customer needs, while
placing the highest priority on environmental conservation as well as safety and disaster prevention.

The surface structureof the material canbe observed finely.
Also, identical andquantitative analysis

is possible.

We offer comprehensive strength to respond to any and all kinds of needs from the rubber

Formulation Technology
With Masterbatch, just a change in any formulation will result in a
drastic change to rubber properties.
Therefore, an appropriate formulation design backed by a wealthof experience is essential, and formulation design is an extremely
important factor that determines the life of product differentiation.
We take pride in our highly ranked research achievements within
the industry and we look to continue to respond accurately toneeds that are increasingly diverse and sophisticated.

Assessment Technology
Requests from customers are infinitely diverse andMasterbatch specifications differ depending on eachcustomer.
In order to provide a Masterbatch with a quality thatsatisfies all customer demands, we have prepared an
exhaustive assessment system.

Raw Materials Knowledge

Mastering molding processes

In order to manufacture Masterbatch, it is important to fully
understand the properties and characteristics of raw materials.
By leveraging our raw materials knowledge that we haveaccumulated for over half a century, we have started toglobalize raw materials, making it possible to provide raw
materials to our customers at a competitive price.

We believe it is necessary to fully master the molding andprocessing processes that are conducted by customers
so that we can provide customers with a Masterbatchthat they can use with a high level of satisfaction.
By establishing a relationship of trust with our customers,
we are also demonstrating our commitment to acquire
knowledge about the molding processes they use.

Production system that
supports stable supply
We have a production system that covers not only
domestic but also overseas areas that enables us topromptly and stably supply a wide range of productsthat meet customer needs.
Furthermore, in order to supply high-quality
products to customers, we conduct thorough quality
management at all domestic and overseas bases.
