Durium is a highly durable synthetic resin developed in 1929. It was used in phonograph record production, as well as in the casting process for metallic type and in the aeronautics industry.
Origin
The resin was the result of research by Dr Hal T Beans, professor of chemistry at Columbia University.[1]
Properties
The resin is flexible, tasteless, odourless and highly resistant to heat. The resin was heated to 230 degrees Celsius in production of records.
Applications
The material was commercialised by the Durium Products, Inc., as the medium for Hit of the Week records, from 1930 to 1932. The resin was bonded to a cardboard substrate and, being much lighter than its predecessor shellac, was sold at newstands for only 15 cents per disc.
