Reclaimed Rubber,Demand for crude rubber soon outstripped supply, with prices tripling even before the Civil War. There was a great economic incentive to spur the development of methods of reusing scrap vulcanized rubber.

The Compounding and Vulcanization of Rubber, involve complicated chemical reactions, of which vulcanization is the most important. In addition, chemical analysis of the raw materials and of the completed products may be required. Thus this knowledge is necessary in order to select the proper test methods.

Fluorocarbon Elastomers,cessibility and greatly improved compression set and steam resistance. There are now five manufacturers (Table 14.1). By 1983, world-wide usage (excluding the U.S.S.R.) surpassed 7 million pounds worth over $80,000,000, but their value-in-use in terms of critical problems solved is far greater.

Thermoplastic Elastomers,le melt to a solid rubber-like object is rapid, reversible, and takes place on cooling. Some thermoplastic elastomers can be dissolved in common solvents and regain their properties when the solvent is evaporated. These transitions are shown in Fig. 16.1.
