Teijin Chemicals Ltd.

Teijin Chemicals Ltd., the core company of the Teijin Group's plastics business, has developed a transparent, flame-retardant polycarbonate (PC) resin measuring just 1.5 mm, what the company claims is the thinnest resin of its kind. The ultrathin PC resin is bromine-free and phosphorus-free, and its flame resistance level is equivalent to UL94V-0, the company says. Despite being so thin, the new resin has ali the inherent characteristics of other PC resins, including transparency, moldability, dimensional stability and electrical properties, Teijin says.

Teijin will supply two grades, one for injection molding and the other for extrusion molding. The former can serve as a substitute for glass components in LED lighting fixtures, etc., while the latter is expected to find uses in sheets mainly for LED lighting covers. Flame-retardant PC resins are widely used in electrical and electronic products and office equipment. The demand for thinner grades has risen with the development of increasingly smaller and thinner products in a variety of fields. Teijin also produces UL94V-0 PC resins with thicknesses starting at 2 mm, but its new resin is expected to satisfy more exacting needs for thinner grades,
