TABLE OF CONTENTS This report is intended for busy specialists of various kinds (both technical and commercial) who need to strengthen or update their understanding of the wider additives scene. The Internet is widely thought to provide all the information needed in this and many other fields, but the time taken to search hundreds of complex websites is rarely costed. When the time factor is coupled with the obvious commercial self-interest motivating many writers of Internet material, an objective and independent summary of the subject appears cost-effective in the long term.
Rapra Technology Ltd. has reviewed the additives industry twice before, with reports authored by Dr. Peter Dufton, published in 1994 and 1998. Since then, the world has changed. The centre of gravity of the world s plastics industry has shifted towards Asia-Pacific, following the globalisation of manufacturing in most industries. Companies have undergone restructuring, mergers etc. New manufacturing processes and specifications in the areas of electronics, vehicles, packaging and medical devices are altering customers needs.
Additive products have been improved, and several completely new products have been marketed. Individual polymers such as PVC and polypropylene have undergone changes in relative importance and market share. New health and safety considerations and regulatory pressures have had major effects on the sales of certain additives, especially heat stabilisers, brominated flame retardants and plasticisers. The trend towards recycling is affecting additive selection.
Other important developments since 1998 include the increasing popularity of clarifying agents, compatibilisers, light stabilisers and antimicrobial additives.
