Handbook of Foaming and Blowing Agents provides useful guidance to assist practitioners in the more efficient and effective selection of foaming methods and blowing agents. The book focuses on the selection of additives for a diverse range of foaming processes, which can be enhanced using modern chemical means to improve product quality, speed up the process, and broaden the range of products that can be produced using foaming technology. Foamed polymers have many beneficial properties, including lower density, high heat and sound insulation, and shock absorbency. Foamed plastic parts are now a ubiquitous part of everyday life—from food packaging to seat cushions. As the application of foamed polymers expands and diversifies, a variety of foaming techniques and equipment are available to produce very diverse range of products. Foaming methods are generally established, but very little is known about the composition of materials to be processed and the additives to enhance foam products or make the foam production more economical. The book introduces useful analytical techniques for foaming, and thoroughly discusses the environmental impact of foaming processes. - Introduces the fundamental mechanisms of action of blowing agents and foaming - Includes best practice guidance to help engineers and technicians improve the efficiency of their existing foaming processes - Enables practitioners to select blowing agents and foaming methods more effectively, reducing the risk of poor specification - Introduces useful analytical techniques for foaming - Discusses the environmental impact of foaming processes

Although plastics are extremely successful commercially, they would never reach acceptable performance standards either in properties or processing without the incorporation of additives. With the inclusion of additives, plastics can be used in a variety of areas competing directly with other materials, but there are still many challenges to overcome. Some additives are severely restricted by legislation, others interfere with each other-in short their effectiveness varies with circumstances. Plastics Additives explains these issues in an alphabetical format making them easily accessible to readers, enabling them to find specific information on a specific topic. Each additive is the subject of one or more articles, providing a suffinct account of each given topic. An international group of experts in additive and polymer science, from many world class companies and institutes, explain the recent rapid changes in additive technology. They cover novel additives (scorch inhibitors, compatibilizers, surface-modified particulates etc.), the established varieties (antioxidants, biocides, antistatic agents, nucleating agents, fillers, fibres, impact modifiers, plasticizers) and many others, the articles also consider environmental concerns, interactions between additives and legislative change. With a quick reference guide and introductory articles that provide the non-specialist and newcomer with relevant information, this reference book is essential reading for anyone concerned with plastics and additives.

Foams are gas filled integral structures in which the gas is finely dispersed throughout acontinuouslyconnected solid phase. The bulk density is usually substantially lower than that of the solid component, and for the foams which form the focus for this book the volume fraction of the gas phase is considerably greater than 0.5 and in most instances in excess of 0.9. Many ofthe materials encountered in every day experience, such as bread, plants and trees, structural materials for buildings, comfort materials for domestic and automotive seating, shock absorbers or car bumpers and materials for noise control, have one thing in common - the cellular nature of their physical structure. Whyare thesestructuressoimportantin the naturaland man-made world? The reasons are both technical and commercial. From a technical viewpoint cellular materials offer: 1. high specific stiffness and strength - making them suitable for structural applications; 2. closeto idealenergymanagement - hencetheir useinthermalandacoustic insulation, vibration damping, acoustic absorption and shock mitigation; and 3. comfort - hence their use for domestic and automotive seating.
