Practical Guide To Flexible Polyurethane Foams

Flexible and viscoelastic polyurethane foams have enormous potential as viable business ventures and have replaced many traditional materials used in everyday life. This book describes the chemistry of flexible and viscoelastic polyurethane foams as well as calculations and formulating methodology for quality production. The author presents detailed information on foam manufacturing, based on over 45 years of hands-on industry experience.

Polyurethanes are very versatile and exciting materials of the plastics family. Although there are many types, the flexible and viscoelastic foams have opened up vast possibilities as viable business ventures and expanding applications, and have established themselves as an essential part of daily life, replacing traditional materials over the years. This book imparts a sound knowledge of flexible and viscoelastic polyurethane foams from their chemistry to calculations and formulating methodology for quality production. The author presents very valuable detailed information on foam manufacturing based on more than 40 years hands-on experience in the local and international situations. The detailed presentation of two manufacturing setups will greatly benefit entrepreneurs, medium-volume producers and large-volume manufacturers. For entrepreneurs, the innovative low-cost startup, high-profit, tried and tested methods will be very encouraging. The medium-to-large-volume producers will find the information provided interesting and practical to solve the inherent problems of excess wastage, better process control and plant efficiency, thereby enhancing profitability. Due to global environmental concerns, as polyurethane chemical components move from petroleum sources to bio-based renewable resources, developers are facing interesting challenges. For continued profitable production, challenges facing the foam machinery manufacturers will be to offer cost-effective, highly efficient and compatible machinery to producers. This book provides practical guidance in all aspects of the manufacture of flexible polyurethane foams, and is an ideal information source for students, teachers, 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.

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.

A Practical Guide to Plastics Sustainability: Concept, Solutions, and Implementation is a groundbreaking reference work offering a broad, detailed and highly practical vision of the complex concept of sustainability in plastics. The book's aim is to present a range of potential pathways towards more sustainable plastics parts and products, enabling the reader to further integrate the idea of sustainability into their design process. It begins by introducing the context and concept of sustainability, discussing perceptions, drivers of change, key factors, and environmental issues, before presenting a detailed outline of the current situation with types of plastics, processing, and opportunities for improved sustainability. Subsequent chapters focus on the different possibilities for improved sustainability, offering a step-by-step technical approach to areas including design, properties, renewable plastics, and recycling and re-use. Each of these pillars are supported by data, examples, analysis and best practice guidance. Finally, the latest developments and future possibilities are considered. Approaches the idea of sustainability from numerous angles, offering practical solutions to improve sustainability in the development of plastic components and products Explains how sustainability can be applied across plastics design, materials selection, processing, and end of life, all set alongside socioeconomic factors Considers key areas of innovation, such as eco-design, novel opportunities for recycling or re-use, bio-based polymers and new technologies
