RIMTECRIMTEC Corporation
Business Description
Sales of RIM (reaction injection molding) compound and molded products
Established in 2003, Rimtec has an integrated production system starting from the raw
material dicyclopentadiene to the final compound, and bringing together originalcompounding, molding, and design technologies to produce and sell a wide variety ofmolded products such as homebuilder materials and automotive bumpers.
Our head office is located in Tokyo. We have a research laboratory in Zeon
Corporation’s Mizushima Plant, and the subsidiary Telene S.A.S. (France) with an R&D
function in France. We also have a U.S. sales office, Zeon Chemicals L.P. Rimtec
acquired and merged with Zeon Rim, a manufacturer of molded products, on April 1,2020.
No. of Employees
As of March 31, 2021: 30 (25 men, 5 women)

RIM molding using the raw material dicyclopentadiene (an olefin-based thermosettingresin) is an innovative energy-saving, resource-saving technology which, compared tomolding using other types of resin, generates relatively limited CO 2 emissions over theprocesses of raw materials procurement, resin preparation, forming and waste disposal.
Rimtec is thus able to supply environmentally-friendly resin blending liquid all over theworld.
Rimtec’s large molded products are lightweight and feature excellent shock resistance,
and as a result have a wide range of applications. These include large products withcomplex shapes, such as construction and agricultural machinery body panels, and truck
and bus body panels, as well as water purification tanks, large valves, housing
President
construction materials, etc.

In addition, we are developing electrical and electronic applications that require goodfilling properties for filling small spaces (taking advantage of our products’ low viscosity)and low dielectric properties, and high-frequency applications. We also expect to develop a wide range of new applications
through the development of new adhesion methods for filler, fiber and metals.
Rimtec seeks to contribute to improvement of the global environment and development of new products by expanding ourbusiness for environmentally-friendly RIM blended compound for molding while contributing to employment at production
contractors and customers, and helping to revitalize local communities.

Safety Initiatives
PolicySafety First! Employees act responsibly and coordinate closely with production contractors and customers to achieve zeroaccidents and disasters.

Specific Initiatives
1. Production quality meetings with production contractors
・We report on production and quality management, and provide education on chemical substance regulations and accident
case studies.
2. Mutual inspections with production contractors (once/year)
・Rimtec’s Mizushima Plant and our production contractors jointly perform mutual RC activities, 5S and safety inspections.
3. Customer safety education (once/year)
・Distribute safety education materials to all customers
・Conduct briefings on the latest versions of laws and regulations
・Visit new customers to give guidance
4. Corporate culture development
・Since FY2015, we have been conducting mutual 5S safety activities with production contractors.
・Since FY2017, we have been carrying out monthly productivity improvement activities for production contractors, incollaboration with the NPS Promotion Group at Zeon’s Production Innovation Center.

Environmental Impact Reductions
Policy・Increase thermal recycling of waste plastic, and begin surveys and research on chemical recycling and material recycling
・Reduce the environmental impact of substances in products based on the regulations in various countries
Specific Initiatives
1. Reducing industrial waste discharge
We have been working to reduce landfill waste since FY2015 and have made further
reductions by establishing a route for sorting and recovering middle insert components
in waste plastic, recycling metal components, and conducting thermal recycling ofwaste plastic components.
2. Compliance with the laws and regulations of applicable countries
We confirm the laws and regulations of various countries with our global subsidiaries,
and are targeting product development and sales expansion to reduce environmental
impact.

Relationship with Employees
PolicyWe strive to be a company that understands and welcomes the diverse values and backgrounds of employees regardlessof gender, age, nationality, or other attribute, and where employees can take pride in working. We are focused on
developing world-class human resources.
Specific Initiatives
1. Development of world-class human resources
・Participate actively in overseas regulatory seminars so as to be able to prevent legal problems from developing・While ourin-house operatives already provide overseas technical instruction for operations staff using online chat and Zoom, there
are limits as to what can be achieved using this approach, so we are creating technical support video content, with theaim of completing it by the end of March 2022
2. Sharing our values
・We formulated the Mission Statement of Global RIMTEC Group to establish globalvalues.
・Through the holding of Taimatsu (Torchlight) activities, we are working to strengthen
dialog within the RIMTEC Group, and to enhance the collaborative relationshipbetween Group member companies.
・We are encouraging all RIMTEC Group employees to ambitiously challengethemselves to realize their goals for 2030.
Taimatsu (Torchlight) activities
conducted jointly by three regions

Relationship with the Local Community
Grow together with the community and contribute to community revitalization, leading to the sustained development ofRimtec.
Specific Initiatives
1. Firefighting activities and cherry blossom viewing with a local firefighting
department
The cherry blossom viewing with partner companies, the volunteer fire corps, andlocal residents from the Honjo district, which in past years was held regularly after
firefighting training, had to be cancelled this year because of the COVID-19 pandemic.
In the future, we plan to strengthen ties with everyone in the local community byholding get-together events using different formats.

2. Participation in Omoshiro Taiken (fun experience), a public event held at Okayama Research Park
Omoshiro Taiken, which is organized by Okayama Prefectural Government andwhich Rimtec had been participating in every year since 2012, was cancelled this year
because of the COVID-19 pandemic.
This event provides children with the opportunity to experience science andtechnology in a fun manner. Children are able to visually experience the processes bywhich the raw materials based on the chemical reactions that we use to produce
resin. We are looking forward to participating in this event again if it is relaunched inthe future.

3. R&D through industry-university collaboration
Rimtec’s Mizushima Plant conducts joint research to develop fundamental technologies in collaboration with Okayama
University and Kyushu Institute of Technology.
We also undertake collaborative research on application products with the Railway Technical Research Institute (RTRI).
4. Industry creation in the Chugoku region
To further the development of new catalysts, we undertake the development ofvarious types of catalysts using 5L glass reactors at a laboratory in Okayama
University’s Collaborative Research Center.
We also make effective use of a prototype development room (100m 3) andlaboratory (50m3) at the Okayama Researchpark Incubation Center (ORIC) to develop
prototypes of new types of electrical insulating materials, etc. The photo on the rightshows a 200L mixing tank installation, operation of which began in December 2021.

We presented research findings regarding “composite molding resin of hydrocarbon based thermosetting resin andfullerene C60” based on collaborative research with the Kyushu Institute of Technology to the Institute of ElectricalEngineers of Japan (IEEJ). We also gave a joint presentation, with the Kyushu Institute of Technology, on the resistance todielectric breakdown of hydrocarbon based thermosetting resin, at the annual meeting of the IEEJ, held in March 2021.
Another presentation was given in December 2020 at the 99th Meeting of the Cryogenics and Superconductivity Society ofJapan.
