Polyolefin compound makes fire-safe conduit.

A low-smoke, zero-halogen polyolefin compound originally introduced for wire insulation has been reformulated for use in semi-flexible cable conduit. The new version of Fireguard LSZH from Teknor Apex Co., Pawtucket, R.I., has been adopted ibr extrusion of coilable conduit by Arnco Corp. of Elyria, Ohio. Its initial use is for a five-mile long underground project for the Chicago Transit Authority railroad system.

The major current market for Fireguard LSZH conduit compounds is in Europe, where regulations favor plastic replacement of metal conduit and smoke-toxicity limits are particalarly stringent. But Teknor sources see potential in the U.S. for conduit used by cable-TV, electric-utility, and natural-gas distribution companies. Tel: (401) 725-8000,
