Elastomer Engineering Guide - James Walker

Rubber was first brought to Europe in 1493 from the Americas by Coluus, but it remained little more than a novelty for over 200 years. Interest eventually began to grow, and in 1770 Joseph Priestley noted its ability to rub out pencil marks, hence the name ''rubber''. This was followed by a rapid growth in technical developments and appliions in the 19th century. Rubber began to …
