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

: q! ]$ H' U! {& R. Rby 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

rubber can be further manipulated by varying the processing steps or manufacturing

but also on the efficiency of the processing operations. In the last few decades new materials

This handbook aims to provide a basic foundation in rubber technology and to collate

& d" r$ [$ V2 Q6 {0 b" t' Hfields. The handbook is intended to serve the needs of those who are already in the
3 z- I6 o6 c# H# Zrubber industry and of new entrants who aspire to build a career in rubber and allied

find the handbook very helpful.
Fourteen chapters deal with natural rubber, synthetic rubbers, thermoplastic elastomers,

automotive applications, footwear, rubbers in construction, durability of rubber products,

whom this handbook would not have been a reality. We are especially grateful to the
commissioning editor, Ms Frances Powers, for her unique combination of professionalism
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
