Once in the atmosphere, certain molecules have a very damaging effect on the ozone layer. Amongst these molecules are CFCs, a very common blowing agent, whos effect on the ozone layer is well documented, and had lead to its dramatic decline in use. This has meant replacements have had to be found, resulting in a large amount of research to find a new generation of blowing agents which have no impact on the ozone layer. This research has lead to other advances in blowing agent technology, most notably the formulations and processes themselves.

In an attempt to collate this new research, Rapra Technology brought together experts from many European countries to provide a valuable insight into the progress of their research. The papers presented at this conference covered the latest advances within the industry, discussing new processing technologies, environmental concerns and areas of strong growth.

The subjects covered included:

Modification of Axodicarbonamide Decomposition Characteristics

HFC-245 FA: A Non Flammable Liquid Blowing Agent for Rigid Polyurethanes

A Status Report on the Development of HFC Blowing Agents for Rigid Polyurethane Foams

Influence of the Activity of Blowing Agents in Foamed Rubber Articles

Foaming Plastics with Expancel Microspheres

How to Get the Most Out of Endothermic Blowing Agents

PVC Foam: Blowing Agents and Processing Aids

Endothermic Blowing Agents

Combined use of Endothermic and Exothermic Chemical Blowing Agents

The 11 papers from the meeting have been assembled to provide a comprehensive record of this highly successful seminar.
