Teijin Chemicals Limited launched a polyester-based resin with a special molecular structure

September 13/2011

(PlasticsToday) -- Teijin Chemicals Limited (Tokyo) has launched a polyester-based resin with a special molecular structure that emits blue fluorescence when exposed to radiation. Calling the Scintirex product a "revolutionary low-cost radiation-fluorescent plastic", Teijin said the plastic can be used in the production of scintillators, the core material in radiation detectors, with potential application by universities, research institutes and manufacturers in a variety of applications including radiation detectors and medical equipment.

The new polyester-based model is said to be superior to conventional scintillators in terms of luminescence, refractive index, and density. Because it is a polyester resin, Scintirex also offers easier moldability.

A proprietary polyester resin developed by Teijin Chemicals in cooperation with Kyoto University Nuclear Reactor Research Institute and the National Institute of Radiological Sciences in Japan, Scintirex is likely based on a polyester polymer of naphthalene dicarboxilate and ethylene glycol, resulting in a polyethylene naphthalate (PEN).
