Download and read online Chemistry and Technology of Epoxy Resins in PDF and EPUB Epoxy resins have been commercially available for about 45 years and now have many major industrial applications, especially where technical advantages warrant their somewhat higher costs. The chemistry of these resins is fascinating and has attracted study by many very able scientists. The technological applications of the epoxy resins are very demanding and there are many new developments each year. The aims of the present book are to present in a compact form both theoretical and practical information that will assist in the study, research and innovations in the field of epoxy resin science and technology. The literature on epoxy resins is so vast that it is not possible to be encyclopaedic and that is not the function of the present text. It is the editor's hope that the selection of topics discussed will provide an up-to-date survey. There is some overlap in the chapters but this is minimal and so each chapter is essentially self contained. As with all chemicals there are toxicological and other hazards. These are not dealt with in this text since a little knowledge can be dangerous, but material supplied can provide information regarding any safety precautions that may be necessary. However, often these precautions are not onerous and epoxy resins, or more specifically the hardeners, can be handled readily. It is hoped that this text will provide an up-to-date outline of the science and technology of epoxy resins and stimulate further research into unsolved problems and assist further technological developments.
Download and read online Handbook of Thermoset Plastics in PDF and EPUB Thermosetting plastics are a distinct category of plastics whose high performance, durability and reliability at high temperatures makes them suitable for specialty applications ranging from automotive and aerospace through to electronic packaging and consumer products (your melamine kitchen worktop is a thermoset resin!). Recent developments in thermoset plastics technology and processes has broadened their use exponentially over recent years, and these developments continue: in November 2011, French scientists created a new lightweight thermoset that is as strong and stable as previous materials yet can be easily reworked and reshaped when heated which makes it unique amongst thermosets and allows for repair and recycling. The Handbook of Thermoset Plastics, now in its 3rd edition, provides a comprehensive survey of the chemical processes, manufacturing techniques and design properties of each polymer, along with their applications. Written by a team of highly experienced practitioners, the practical implications of using thermoset plastics are presented – both their strengths and weaknesses. The data and descriptions presented here enable engineers, scientists and technicians to form judgments and take action on the basis of informed analysis. The aim of the book is to help the reader to make the right decision and take the correct action – avoiding the pitfalls the authors’ experience has uncovered. The new edition has been updated throughout to reflect current practice in manufacturing and processing, featuring: Case Studies to demonstrate how particular properties make different polymers suitable for different applications, as well as covering end-use and safety considerations. A new chapter on using nanoparticles to enhance thermal and mechanical properties. A new chapter describing new materials based on renewable resources (such as soy-based thermoset plastics). A new chapter covering recent developments and potential future technologies such as new catalysts for Controlled Radical Polymerization. Goodman and Dodiuk-Kenig provide a comprehensive reference guide to the chemistry, manufacturing and applications of thermosets. Updated to include recent developments in manufacturing – from biopolymers to nanocomposites. Case Studies illustrate applications of key thermoset plastics.
Download and read online Polybenzoxazines in PDF and EPUB Polybenzoxazine is a novel class of thermosetting material that belongs to the family of addition-curable phenolic resins. It is a promising high temperature polymer in view of its outstanding thermal, physical, and mechanical properties that are beneficial for their application in aerospace and microelectronics industries. The first objective of this book is to provide the reader with information on the developments and properties of contemporary thermosetting polymers, along with the chemistry and curing kinetics of polybenzoxazines. The unique properties of polybenzoxazines originate from their hydrogen-bonded structures. The second objective of this book is to furnish detailed information on the syntheses and properties of various polybenzoxazines prepared from different monomers. They are categorised mainly into two types; firstly, the benzoxazine monomers containing additional crosslinking groups such as maleimide, nitrile, propargyl, acetylene, furan etc. The other is based on monomers synthesised from different phenols and amines of varying backbone structures. The third objective of this book is to elaborate the preparation and properties of the modified polybenzoxazines such as their blends and nanocomposites. The final objective of this book is to provide specific information on the degradation chemistry of polybenzoxazines under thermal, photochemical and chemical environments. The potential areas of application of these polymer systems are highlighted. This volume is intended to be a quick reference to researchers from the academia and industries on polybenzoxazine science.
Download and read online Handbook of Thermoset Plastics in PDF and EPUB Polybenzoxazines (PBz) belong to the family of new generation phenolic resins. They have emerged as addition-curable polymers. This feature obviates many of the shortcomings associated with conventional phenolic resins. They are endowed with excellent thermal, physical, and thermo-physical properties, and surpass the features of many conventional and state-of-the-art polymers. These unique materials offer extraordinary characteristics: near zero shrinkage, no release of volatiles during cure, high Tg, low flammability, and high UV and chemical stabilities. Given the breadth of molecular design flexibility, a wide variety of polybenzoxazines can be developed. PBz equipped with additional curing groups can generally enhance the overall thermal and mechanical properties. Blends with epoxy resins, cyanate esters, and bismaleimides offer other opportunities for fine-tuning properties. This chapter gives an account of the developments of PBz materials from their inception to the current level of application in engineering areas.

Download and read online Phenolic Resins in PDF and EPUB A backward glance of the many new industries that emerged in the 20th century would surely recognize communications, automobile, aircraft, computer and several others that have had a global impact on world economy. Yet another industry, and an often neglected industry, made its debut early in the 20th century - the Plastics Industry. The Plastics Industry owes its identity to the brilliance of Dr. Leo Hendrik Baekeland (1863 -1944). He discovered the technique, currently in use to this day, to manu facture highly crosslinked plastics by transforming monomerk and/or oligomeric phenolic materials into attractive phenolic products. Today phenolics represent one of the many different types of com mercially available plastics (thermoset and thermoplastic). Phenolics are distinguished by a broad array of application areas that utilize phenolics as compared to other thermoset or thermoplastic resins. Thermoplastic resins transformed into molded products, films or synthetic fibers (polypropylene as an example) are rapidly recognized as "plastics" whereas the phenolic resin is a component in a material system and the identity of the phenolic resin within the system is not easily identified as "plastic". These systems consist of fiber reinforced composites, honeycomb paneling, electrical Iaminates, acid resistant coatings, wood panels, glass fiber or rock wool insulation. Phenolic resin identity is hidden and has little consumer recognition or identity.
