Particulate-Filled Polymer Composites, Second Edition
Smithers Information Ltd, September 2003, Pages: 560
This is an updated version of the book first published in 1995. The use of particulate fillers in polymers has a long history, and they continue to play a very important role today. In the relatively short time since the publication of the first edition of this book, much has changed and all the chapters have been updated and revised, and a completely new chapter covering the latest developments in nano-filler technology is included.
The aim of this book is to provide a guide to the fundamentals of the use of particulate fillers, which is accessible to people from the many different industries and disciplines who have an interest in the subject.
Topics covered include:
- Selection and Use of Particulate Fillers
- Types of Particulate Filler
- Filler Surfaces and their Characterisation
- Surface Modification and Surface Modifiers
- Preparation and Mixture Characterisation of Mineral Filler Polymer Compounds
- Particulate Fillers as Flame Retardants
- Particulate Fillers in Elastomers
- Particulate Fillers in Thermoplastics
- Particulate Fillers in Thermosets
- Composites Using Nano-Fillers

Roger Rothon is now an independent consultant, specialising in the production, surface modification and application of particulate fillers for polymer composites. He previously worked for ICI in the UK for over 25 years, most of this time being spent in the fillers area. While in ICI he was responsible for several new product developments, including new types of coupling agents for silica and calcium carbonates and novel conductive and magnetic fillers. After leaving ICI, he was Technical Manager for Flamemag International for 8 years. In this position, he led the development of a new process for the production of magnesium hydroxide flame retardant fillers.
He has several patents and many scientific publications, and was the editor and main contributor to the first edition of " Particulate Filled Mineral Composites". In 1996 he was made a visiting Professor at the Manchester Metropolitan University, where he is now involved in research on filler surface modifiers. Roger Rothon has also spent considerable time as a visiting scientist at the CSIRO Division of Minerals in Melbourne Australia.
