Biocides In Plastics

This Rapra Review Report examines the use of biocides in plastics with reference to material types and application requirements. The commonly available biocides are reviewed and details of their strengths and weaknesses are provided. The author reviews the frequently used test methods for fungi and bacteria, and, in an ever-changing regulatory environment, explores the influence of legislation on the current and future use of such biocides. This detailed and state-of-the-art review is supported by an indexed section containing several hundred key references and abstracts selected from the Polymer Library database.

Biocidal polymers are designed to inhibit or kill microorganisms such as bacteria, fungi and protozoans. This book summarizes recent findings in the synthesis, modification and characterization of various antimicrobial polymers ranging from plastics and elastomers to biomimetic and biodegradable polymers. Modifications with different antimicrobial agents as well as antimicrobial testing methods are described in a comprehensive manner.

Brydson's Plastics Materials, Eighth Edition, provides a comprehensive overview of the commercially available plastics materials that bridge the gap between theory and practice. The book enables scientists to understand the commercial implications of their work and provides engineers with essential theory. Since the previous edition, many developments have taken place in plastics materials, such as the growth in the commercial use of sustainable bioplastics, so this book brings the user fully up-to-date with the latest materials, references, units, and figures that have all been thoroughly updated. The book remains the authoritiative resource for engineers, suppliers, researchers, materials scientists, and academics in the field of polymers, including current best practice, processing, and material selection information and health and safety guidance, along with discussions of sustainability and the commercial importance of various plastics and additives, including nanofillers and graphene as property modifiers. With a 50 year history as the principal reference in the field of plastics material, and fully updated by an expert team of polymer scientists and engineers, this book is essential reading for researchers and practitioners in this field. Presents a one-stop-shop for easily accessible information on plastics materials, now updated to include the latest biopolymers, high temperature engineering plastics, thermoplastic elastomers, and more Includes thoroughly revised and reorganised material as contributed by an expert team who make the book relevant to all plastics engineers, materials scientists, and students of polymers Includes the latest guidance on health, safety, and sustainability, including materials safety data sheets, local regulations, and a discussion of recycling issues

Due to the possibility that petroleum supplies will be exhausted in the next decades to come, more and more attention has been paid to the production of bacterial pl- tics including polyhydroxyalkanoates (PHA), polylactic acid (PLA), poly(butylene succinate) (PBS), biopolyethylene (PE), poly(trimethylene terephthalate) (PTT), and poly(p-phenylene) (PPP). These are well-studied polymers containing at least one monomer synthesized via bacterial transformation. Among them, PHA, PLA and PBS are well known for their biodegradability, whereas PE, PTT and PPP are probably less biodegradable or are less studied in terms of their biodegradability. Over the past years, their properties and appli- tions have been studied in detail and products have been developed. Physical and chemical modifications to reduce their cost or to improve their properties have been conducted. PHA is the only biopolyester family completely synthesized by biological means. They have been investigated by microbiologists, molecular biologists, b- chemists, chemical engineers, chemists, polymer experts, and medical researchers for many years. PHA applications as bioplastics, fine chemicals, implant biomate- als, medicines, and biofuels have been developed. Companies have been est- lished for or involved in PHA related R&D as well as large scale production. It has become clear that PHA and its related technologies form an industrial value chain in fermentation, materials, feeds, and energy to medical fields.

Databook of Biocides contains critical data on the most important biocides in use today. The selection includes generic and commercial biocides, which are approved for use in the European Union and the US. Data on generic biocides come from numerous sources, and can be easily compared with manufacturer information on commercial biocides, which are also included. Physical properties are presented—including volatility, solubility, and concentration—as are health and safety considerations (such as flash point, autoignition temperature, risks of skin and eye irritation, mutagenicity and carcinogenicity) and first-aid guidance. Ecological properties are also emphasized, with data on biodegradation and acquatic toxicity. Particular emphasis is placed on usage considerations, including recommended material-biocide combinations, processing methods and dosages, and features and benefits for each biocide. The book also contains an introductory chapter in which general indicators of performance of biocides are discussed. Presents practical information for use in the lab and the field, including recommended processing methods, recommended dosages, and potential substitutes Emphasizes environmental, health, and safety properties to ensure safe deployment Includes the most commonly used biocides in compliance with the latest regulations in the European Union, US, and worldwide Covers the physical properties, ecological properties, and performance indicators of biocides

Most plastics and polymers used for consumer goods and technical applications contain numerous additives, many of which are potentially hazardous to human health and the environment. The Handbook for the Chemical Analysis of Plastic and Polymer Additives provides a detailed reference for the analysis of additives that are most widely used in

In June 1968, TRW Systems Group, under contract to the U.S. Department of Health, Education, and Welfare's Bureau of Solid Waste Management, undertook a project to investigate analytically the use of waste plastic materials for the production of high-volume process chemicals. The objectives of the analysis were as follows: to identify waste plastic/coreactant reaction products with potential commercial value; to identify waste plastic/air combustion products that are potential air pollutants; to conceive of and provide technical and economic evaluations for chemical processes utilizing waste plastics as raw materials; and to identify potential R & D programs leading to the development of commercially viable chemical processes.
