Traffolyte
Traffolyte, sometimes spelled Traffolite, was a brand name for multi-layered phenolic plastic sheets suitable for engraving. Each layer was a different colour so engraved letters or shapes would be a different colour from the unengraved portions. Thus it could be used for name tags, labels and signs.
History[edit]
The material dates back to 1927, when it was first produced by Metropolitan-Vickers Electrical Ltd. at their Trafford Park factory in Manchester, UK for transformer labels. The complete business was sold to De La Rue Insulation Ltd[1] in 1945; De La Rue exited this business in the early 1960s. There are a large number of companies manufacturing bi- and tri-layer phenolic engraving stock and it has become a generic term; no record of its having been a registered trademark in the United States or UK has been found.
Hazards[edit]
Traffolyte signs and labels are cheap to produce, and were very popular in the past. However, phenolic dust is now recognized as a health hazard and so precautions must be taken during label production.
