The Modern Plastics Handbook offers a thorough and comprehensive technical coverage of all aspects of plastics materials and processes, in all of their forms, along with coverage of additives, auxiliary equipment, plastic product design, testing, specifications and standards, and the increasingly critical subject of plastics recycling and biodegradability. Thus, this Handbook will serve a wide range of interests. Likewise, with presentations ranging from terms and defin- itions and fundamentals, to clearly explained technical discussions, to extensive data and guideline information, this Handbook will be use- ful for all levels of interest and backgrounds. These broad objectives could only have been achieved by an outstanding and uniquely diverse group of authors with a combination of academic, professional, and business backgrounds. It has been my good fortune to have obtained such an elite group of authors, and it has been a distinct pleasure to have worked with this group in the creation of this Handbook. I would like to pay my highest respects and offer my deep appreciation to all of them. The Handbook has been organized and is presented as a thorough sourcebook of technical explanations, data, information, and guide- lines for all ranges of interests. It offers an extensive array of property and performance data as a function of the most important product and process variables. The chapter organization and coverage is well suited to reader convenience for the wide range of product and equipment categories. The first three chapters cover the important groups of plas- tic materials, namely, thermoplastics, thermosets, and elastomers. Then comes a chapter on the all important and broad based group of additives, which are so critical for tailoring plastic properties. Following this are three chapters covering processing technologies and 0267146_FM_Harper_Plastics_MHT 2/24/00 4:39 PM Page xii xii Preface equipment for all types of plastics, and the all important subject of auxiliary equipment and components for optimized plastics process- ing. Next is a most thorough and comprehensive chapter on design of plastic products, rarely treated in such a practical manner. After this, two chapters are devoted to the highly important plastic materials and process topics of coatings and adhesives, including surface finishing and fabricating of plastic parts. Finally, one chapter is devoted to the fundamentally important areas of testing and standards, and one chapter to the increasingly critical area of plastic recycling and biodegradability. Needless to say, a book of this caliber could not have been achieved without the guidance and support of many people. While it is not pos- sible to name all of the advisors and constant supporters, I feel that I must highlight a few. First, I would like to thank the Modern Plastics team, namely, Robert D. Leaversuch, Executive Editor of Modern Plastics magazine, Stephanie Finn, Modern Plastics Events Manager, Steven J. Schultz, Managing Director, Modern Plastics World Encyclopedia, and William A. Kaplan, Managing Editor of Modern Plastics World Encyclopedia. Their advice and help was constant. Next, I would like to express my very great appreciation to the team from Society of Plastics Engineers, who both helped me get off the ground and supported me readily all through this project. They are Michael R. Cappelletti, Executive Director, David R. Harper, Past President, John L. Hull, Honored Service Member, and Glenn L. Beall, Distinguished Member. In addition, I would like to acknowledge, with deep appreciation, the advice and assistance of Dr. Robert Nunn and Dr. Robert Malloy of University of Massachusetts, Lowell for their guidance and support, especially in selection of chapter authors. Last, but not least, I am indebted to Robert Esposito, Executive Editor of the McGraw-Hill Professional Book Group, for both his support and patience in my editorial responsibilities for this Modern Plastics Handbook. It is my hope, and expectation, that this book will serve its reader well. Any comments or suggestions will be welcomed. Charles A.

  • Ask Me About Microscope & Magnification…
    ASK ME ABOUT MICROSCOPE & MAGNIFICATION… Today, an instructor from The Discovery Museums in Acton visited my classroom and led a hands-on program about microscopes and magnification. Ask me to tell you what amazing things I observed looking through lenses! I can tell you how I used water as a magnifier and we can explore together by trying the water lens activity below. I also really enjoyed using the 30x handheld microscopes. Ask me to tell you about all of the objects we checked out in our classroom such as the carpet, my desk surface, my hair and my skin. The hand held microscopes are sold at The Museums’ gift shop, science stores and some electronic shops. WATER SCOPE The first magnifiers were made with water lenses. Try making you own water lens. You will need: Small or large plastic yogurt containers, plastic wrap, pair of scissors, water, large rubber bands What to do: 1.) Ask an adult to cut the bottom of the yogurt container off, leaving at least a 3 inch wide ring. 2.) Cut a piece of plastic wrap and stretch it over the mouth of the yogurt container. Secure it with a rubber band. 3.) Push down gently on the top of the plastic wrap to make a shallow well. 4.) Pour a little water into this well. 5.) Place objects under the container and look through the water at the object. What do you notice? 6.) What happens if you change the amount of water you are looking through? Take it to the next step: Experiment with making additional water scopes.

  • Phthalate Testing ‐ Frequently Asked Questions Updated February, 2009
    Phthalate Testing ‐ Frequently Asked Questions Updated February, 2009 Q. Which specific phthalates is the Consumer Products Safety Information Act (CPSIA) concerned about? A. The six phthalate plasticizers of interest are: Diisononyl phthalate (DINP), Di‐2‐ ethylhexylphthalate (DEHP, sometimes called DOP), di‐n‐octyl phthalate (DnOP), Di‐isodecyl phthalate (DIDP), butylbenzyl phthalate (BBP), and dibutyl phthalate (DBP). Q. What can Polymer Diagnostics Inc. (PDI) test? A. PDI can test raw materials, compounds and finished goods. Q. How does PDI perform the testing? A. Samples are initially extracted (or diluted), and then analyzed by Gas Chromatography‐Mass Spectrometry [GC‐MS]. Depending on the results, additional analyses may be done to verify results and insure accuracy. This helps reduce the potential for false positives. Q. What about false positives? A. Although GC‐MS can reduce the likelihood of mis‐identification, the complexity of many formulations cannot rule this out. Further refinements of the analysis conditions or use of other separation techniques helps to enhance the reliability of the results. In those cases where the interference cannot be eliminated, results will clearly state this fact. Q. What is the current standard for testing for phthalates? A. Some literature has cited ASTM 3421‐75 as applicable for this testing. This method has been discontinued by ASTM, and has not been replaced. The regulatory body responsible for the CPSIA is currently working on recommending an improved method, but this is still in the planning stage. Q. What are the current issues, if any, with the test methods? A. Any method recommended should use current analytical methodologies.

Since then, this important course has been held unchanged in Stuttgart for a long time. During the revision we not only updated figures and contents, but also gave the course a new structure, which I – inspired by didactic seminars of the German University Association – consider more contemporary. Numerous film sequences used in the lectures enable the students to understand the contents more quickly and deeply. I am convinced that the students in my course become well equipped with a comprehensive, fundamental knowledge of plastics and plastics technology for their upcoming professional life. If students want to deepen their knowledge of the subject, they can do so in the three main areas of “Materials Engineering”, “Processing Technology”, and “Product Engi- neering” in other courses later on. This introductory and fundamental lecture series in Stuttgart is an elective course with four lessons per week for master students of process engineering, mechanical engineering (e. g. production engineering, automotive engineering), materials sci- ence, as well as of technology management. The course is actually aimed at techni- cally educated students, but in the meantime non-technical students (economics, environmental issues) choose the course as well.
