Our History

Our Company Name

RIKEN TECHNOS CORPORATION, formerly known as a RIKEN VINYL INDUSTRY CO., LTD., was established in 1951 as a start-up venture originating from RIKEN (Rikagaku Kenkyusho,) basing the business on blending technologies with the new industrial material, PVC (Polyvinyl Chloride.)

The company name “RIKEN TECHNOS” was taken from “RIKEN TECHNOLOGY SUPPLIER.”
It represents our commitment to refine the technologies we have developed so far to take them to an even higher level, to overcome the hurdles

Our Corporate Mark

  • The corporate mark was changed when the corporation’s name was changed in commemoration of the 50th anniversary of the company being founded. Based on the “R” of RIKEN TECHNOS CORPORATION, the mark is meant to symbolize the reliability of our core business, namely compound and film, and the shape of the sweeping wing of a bird in flight which symbolizes our flight into the future.
    The corporate color is the “RIKEN BLUE.” It signifies the technology-oriented heart of RIKEN TECHNOS CORPORATION that treasures individuality and aims for the future.
