Production and sales of resin-based products through rotational molding＜Technology＞
Suiko Co., Ltd. has successfully developed safe and comfortable polyethylene playgroundproducts possessing greater strength and enhanced anti-static properties!

Since polyethylene playground equipment is susceptible, by its nature, to ultraviolet (UV)
degradation, it tends to suffer discoloration or property degradation after being placed
outdoors (and exposed to direct sunlight) for a long time. To combat this problem, we at1

Suiko Co., Ltd. have mixed a high-performance weathering stabilizer into the polyethylene
used to produce our products, and by doing so, we have succeeded in protecting ourplayground equipment from damage from UV radiation. Utilizing this method, we have beenable to boost both the safety and durability of our products: not only have we prevented ourplay equipment from being discolored under the hot sun, but we have also succeeded inextending the lifespan of our equipment.
Recently, together with an additive manufacturer, we have developed some materials
that can prevent the generation of static electricity. With these materials, our company has
successfully created types of polyethylene playground slides that do not readily produce
static electricity, and these slides have been introduced to the market. These are colorfulslides monolithically molded out of polyethylene, and are made in Japan. They are very
accurately made and possess superb quality. It is possible to place an order even for a single
unit of these slides, and the slides can be produced within short deadlines. As they are very
easy to recycle, our polyethylene slides are considered highly eco-friendly.

[History of development]
At Suiko, we have developed polyethylene playground products because we want
children—the creators of our future world—to play on safer and more comfortableplayground equipment. In many cases, items of playground equipment have to be made soas to withstand rigorous weather conditions, since they will normally be installed outdoors.
We have aimed to create playground products that are safe to use even under harsh weather
conditions by boosting the physical properties of the polyethylene used in our play products.
We have also considered that by overcoming the static-related problem of polyethylene, i.e.,
its tendency to become easily charged with static electricity due to poor electricalconductivity, we can determine what we can do further to enhance polyethylene playgroundequipment.

[Originality]
A wide variety of materials are used to produce playground equipment. Metal is not an ideal
material for play equipment because it becomes very hot in the summer sun. Slides made ofiron or of fiber-reinforced plastic (FRP) need to be repainted regularly, and it is difficult topredict when slides made of these materials will crack.
Our polyethylene playground equipment has characteristics not possessed by traditional
polyethylene play equipment: the materials recently developed for our polyethylene playequipment are highly weather resistant and can maintain anti-static effects over the longterm, and such properties will not fade even when our equipment is exposed to rain and2other harsh environmental conditions.

[Future development]
We possess techniques to diagnose UV ray-induced surface degradation of polyethylene
products, and we can recommend when it is appropriate to replace an old polyethylene
playground product with a new one. As we have obtained the “Wide-Area Certificate” fromJapan’s Ministry of the Environment (a certificate that allows a manufacturer to freely collectits products sold to customers when they dispose of them), it is also possible for us torecycle our polyethylene products after they reach the end of their lifespan. From today
onward, we are planning to further expand our line-up of playground products that offer theabove advantages of polyethylene equipment as well as extra value not possessed byforeign play products. In the future, we are considering creating a park that exclusively
features our playground equipment, which may be named “Suiko Land.”＜TOPICS＞

Undergoing earthquake disasters and becoming actively involved in social activities
With its factories located all over Japan, our company has been directly affected by many ofthe major natural disasters that have occurred in the country, such as the Great
Hanshin-Awaji Earthquake, the Great East Japan Earthquake, and large-scale earthquakesthat have struck Kumamoto and Hokkaido. Suiko’s products (e.g., plastic storage tanks andcontainers) have been used in such disaster areas to transport drinking water and water fortoilets. Immediately after the Great East Japan Earthquake, all sales employees of ourcompany temporarily stopped their sales activities and helped with the production ofproducts delivered to the disaster sites. We all focused on delivering our products to thedisaster sites as quickly as possible, and we believe we were able to make some contribution3

to providing basic emergency life support to people in affected areas and helping themrecover from the disaster. Currently, in response to requests from many places and manypeople, we are providing our transport tanks for sanitizers as a means to suppress thespread of coronavirus infections.

Launching a YouTube channel to introduce Suiko’s products
In the spring of last year, we launched a YouTube channel mainly for the purpose of
introducing our products, and to our delight, the channel has been viewed by many people.
Henceforth, we will strive to further enrich the content on our YouTube channel, making surethat the channel will serve as a useful aid or guide to our customers.
We are thinking of using many people’s opinions as reference in developing anddelivering our products, so please feel free to contact us by inquiry form or email.
