Cellular polymers or foamed polymers are an important branch of plastics and are an essential part of daily life. Some of the major sectors of use are bedding, automotive, building construction, furniture, sound/thermal insulation, and packaging.Due to growing global concerns with regard to air pollution, research has led to the fascinating concept of using water as the sole blowing agent to create cellular foams as an alternative to traditional petroleum-based blowing agents (which contribute to air pollution). This strategy has created other possibilities of better and safer foams, and reduced costs are also considerable.With over 45 years of hands-on experience, the author provides in-depth knowledge of water-blown cellular polymers, from their chemistry to formulation and process methodology to produce quality foams. This exciting new phase of the polymer industry is presented in detail with regard to manufacture of standard foams as well as specialty foams. Such descriptions are based on new and emerging technologies, including the challenges and solutions foam producers must face with formulations as well as recommendations for machinery and equipment.This is a comprehensive presentation of all aspects of the technology required to produce water-blown cellular foams with different polymers to meet market demands. This book provides theoretical and practical information as well as guidance, and is an ideal source of information for libraries, students, teachers, foam producers and entrepreneurs.

Drawing on over 45 years of hands-on experience, the author provides in-depth knowledge of water-blown cellular polymers, from their chemistry to formulation and process methodology. This book describes the manufacture of standard and specialty foams using new and emerging technologies. The author gives advice on the challenges foam producers commonly face with regard to formulations and makes recommendations for machinery and equipment.

Polymeric composites with rice hulls have superior properties compared with other polymer composites and are suitable for a wider range of applications. This book explains what it is that makes polymeric composites with rice hulls ideal substitutes for natural wood and how they may help ease global environmental concerns. It is an ideal source of information for researchers, resin-pellet manufacturers, processors and end users.

Polymers are converted into finished products through a series of steps which include mixing in additives and various types of forming. Following an introduction to polymer science and its importance to various fields, the author describes these processes from a practical, application-oriented perspective. Global suppliers of raw materials, machinery and equipment are also given, making this book an invaluable resource for industry practitioners.

This book presents both established and emerging technologies which show the immense possibilities of using non-traditional fillers and stiffening agents in the plastics industry. After an introduction to basic polymer chemistry, a range of non-petroleum-based fillers and stiffening agents for polymer products are identified and their optimal applications given.

Thanks to their unique physico-chemical nature, two-component polyurethane (PU) systems have found widespread industrial application. This book gives practical guidance on the selection of raw materials and machinery, as well as the calculations and formulations necessary for the successful production and processing of two-component PUs. Readers will benefit from the troubleshooting advice based on the author's extensive industry experience.
