Our Business
Shaping the Future with Aromatic Diamines
This is WAKAYAMA SEIKA's mission.
Our Business
WAKAYAMA SEIKA’s aromatic diamines are used as raw materials for high-performance resins that support cutting-edge technologies across numerous industries.
While our product names may not be publicly displayed, our materials play an indispensable role in technologies that underpin everyday products and society, including electronic devices, semiconductors, automobiles, and aerospace applications.
Aromatic diamines are important raw materials for products such as polyimide resins, which possess outstanding heat resistance and mechanical properties. These materials can give plastics unique functionalities, making aromatic diamines truly a “miracle raw material”. These advanced materials still have limitless potential, and through research and development, it is possible to both enhance current functionality and impart new functionality.
Emerging advanced materials and rapidly growing technology sectors increasingly require superior performance characteristics such as excellent insulation and heat resistance. Aromatic diamines are increasingly recognized as a key material capable of meeting these sophisticated performance requirements.
Our Strengths
Since our founding in 1955, WAKAYAMA SEIKA has consistently focused on the research, development, and manufacturing of aromatic diamines.
The extensive product library, insights, technologies, and know-how cultivated through these activities are leveraged in the manufacturing and development processes of chemical and materials manufacturers both in Japan and overseas.
At our R&D center, “Mirai-Sozo-kan”, we conduct cutting-edge research on aromatic diamines, developing innovative products that only we can provide and contributing to technological advancement and improved quality of life.
We also have four manufacturing plants in Wakayama Prefecture, and meet the needs of customers around the world, from mass production to small-lot, high-mix production. We continually work to improve our manufacturing management to ensure a safe and stable supply of high-quality products.
Our Future
WAKAYAMA SEIKA is now moving forward to a new stage of growth.
As we look to the future, we aim to transform from a company that simply manufactures products to customer specifications to a company that creates and delivers value. In other words, we are striving to become a company that can not only "provide materials" but also propose what kind of future can be realized with these materials. We are not just a supplier, but a partner in innovation, leveraging our longstanding strengths and advanced technologies to create new value together with our customers through materials innovation.
At the same time, we remain firmly committed to safe operations and stable product supply as the foundation of our business. We will also continue to contribute to local communities and promote environmental responsibility, helping to build a more sustainable society for future generations.
