Our R&D History

In 1951, we began our compound business with the goal of commercializing technologies for processing polyvinyl chloride (PVC) resin, something we had been working on at RIKEN, the Institute of Physical and Chemical Research. When we began, we were truly a venture company, using small-scale equipment of 9-inch rolls to produce 3 to 4 tons each month. After acquiring formulations technologies, we began working on downstream businesses to increase the added value we offered. We used the technologies we developed to move into the rigid resin field with our calendaring films and into the soft resin field with our wraps for food packaging. These became our primary business segments. In the late 1990s, we expanded our elastomer compound business as a substitute for flexible PVC.
The spirit of venture, which has been passed down since our founding days, represents the very strength of RIKEN TECHNOS and its “RIKEN TECHNOS-ness.” Always keeping this spirit in mind, we will continue taking on R&D activities to make further advances into the future.
