2 t; P/ X2 u" Q; T# D+ s9 TFrom a materials point of view a rubber product is made from rubber and a host of other
% X* D: R; v- G: H) b1 Kadditives, including fillers, vulcanising agents and processing aids along with reinforcing
materials such as textiles. From a manufacturing point of view, a rubber product is made
% u* G+ o' i0 r' v* K# o) U( Rby following several steps: mixing of additives with the rubber (‘compounding’) when
the rubber is unvulcanised and in the plastic state; shaping the rubber compound and/or

‘elastic’ recovery behaviour. The final properties of a rubber product depend on the type

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
fields. The handbook is intended to serve the needs of those who are already in the
1 a! V! }; K5 I% k# O, vrubber industry and of new entrants who aspire to build a career in rubber and allied
/ w- h; @- Q0 H% L2 }( zareas. Materials Science students and researchers, designers and engineers should all
find the handbook very helpful.

accommodated in the current volume and it is intended that a second volume of the

coverage. We gratefully acknowledge the cooperation from all of the contributors, without

commissioning editor, Ms Frances Powers, for her unique combination of professionalism

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
