Leading the industry as the world’s first melt-processable fluoropolymer molding manufacturer
Through the manipulation of high-performance polymers such as fluoropolymers, Junkosha supplies a range of products including wires, cables, tubing, connectors and injection moldings. Junkosha also provides the solution as assemblies or components comprised of these products. As a technology-focused company which delivers the highest quality, Junkosha has consistently pursued research and development since its establishment in 1954. In 1961, Junkosha succeeded in developing the world’s first FEP melt-processable fluoropolymer products, which were enthusiastically embraced by the Japanese market with the coming of the computer age.
