Durium is a highly durable synthetic resin developed in 1929. It was used in phonograph records, as well as in the casting process for metallic type and in the aeronautics industry. Origin. It is a resorcinol-formaldehyde resin, the result of research by Hal T. Beans, professor of chemistry at Columbia University. Properties. The resin is flexible, tasteless, odorless, fire and waterproof. It is highly resistant to heat and was heated to 230 °C (446 °F) in production of records. It is fast-setting, reducing the production cost of items made from it. Applications.
