Highly reactive active species are generated! We will introduce why modification and processing can be done with radiation.
When radiation is irradiated onto polymer materials such as plastics, excitation or ionization occurs in the nearby molecules that the radiation passes through, resulting in the generation of highly reactive active species. Through the reactions of these active species, the cleavage of polymer chains (radiation decomposition) occurs, or reactions that bond polymer chains together in a bridge-like manner (radiation crosslinking) take place. Additionally, if a highly reactive compound is mixed with the polymer along with the active species, it is possible to add new branches to the original polymer chains (radiation graft polymerization). 【Radiation Modification】 ■ Radiation Decomposition: Cleavage of polymer chains ■ Radiation Crosslinking: Reaction that bonds polymer chains together in a bridge-like manner ■ Radiation Graft Polymerization: Adding new branches to the original polymer chains *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company was established in November 1971 with the business purpose of providing gamma ray irradiation services and related technological development. Since then, we have steadily enhanced our facilities, including the addition of two gamma ray irradiation facilities and the establishment of an electron beam irradiation facility, in response to the growing demand for radiation irradiation. Today, we contribute to the development of increasingly important fields such as medical devices, container and packaging materials, feed for laboratory animals, and instruments for bio-research, starting with sterilization and disinfection, as well as modification of polymer materials, electronic materials, and radiation resistance testing of components for nuclear reactors and artificial satellites.
