"Thinnest-ever" transparent PC resin debuts

Teijin Chemicals Ltd., the core company of the Teijin Group’s plastics business, has developed a transparent, flame-retardant polycarbonate (PC) resin capable of producing extruded sheet measuring just 1.5 mm, making this the “thinnest-ever” transparent sheet of its kind.

The PC resin is both bromine- and phosphorous-free, making it environmentally friendly, and its flame resistance level is equivalent to UL94V-0. Despite being capable of extruding sheet so thin, the new resin has all of the inherent characteristics of other PC resins, including transparency, moldability, dimensional stability, and electrical properties.

The Company said it will supply two grades: one is a resin for injection molding and the other for sheet 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, said Teijin.

Flame-retardant PC resins are widely used in electrical and electronic products and office equipment. The demand for thinner grades has risen in line with the development of increasingly smaller and thinner products in a variety of fields, noted Teijin in its release. Teijin chemicals also produces high-quality UL94 V-0 PC resins with thicknesses starting at 2.0 mm, but its new resin is expected to satisfy more exacting needs for thinner grades. —mpweditorial@cancom.com
