From a materials point of view a rubber product is made from rubber and a host of other
additives, including fillers, vulcanising agents and processing aids along with reinforcing

3 f- k) }: ^' I. s, ~. [' W1 @by following several steps: mixing of additives with the rubber (‘compounding’) when

bonding it to a substrate; and finally vulcanising or curing the whole assembly, when
chemical crosslinks are formed between the rubber molecules to give the material its
‘elastic’ recovery behaviour. The final properties of a rubber product depend on the type
of rubber chosen and the additives used and their concentrations. The properties of the

but also on the efficiency of the processing operations. In the last few decades new materials
have emerged and manufacturing has become increasingly automated and more efficient.
This handbook aims to provide a basic foundation in rubber technology and to collate
the most recent developments in the form of chapters, written by experts in their respective

rubber industry and of new entrants who aspire to build a career in rubber and allied
areas. Materials Science students and researchers, designers and engineers should all

and good humour: her prompt and pointed responses to all of our requests for assistance
were invaluable. We wish to commend all of the staff at RAPRA Technology Ltd who
contributed to the excellent production of the handbook, especially Claire Griffiths and
Sandra Hall.
