    This book is for those interested in improving the properties of elastomers. It provides an exhaustive overview of the influence of different types of fillers.Starting with the manufacture and characterization of the fillers, the main factor determining the reinforcement is the rubber-filler interaction, which is discussed in detail and is the parameter part for the reinforcement of elastomers. The filler dispersion and distribution depend on the mixing procedure, the type and content of the filler, the nature of the polymer, and the presence of plasticizer. The rheological behavior and the vulcanizate properties are discussed comprehensively according to their different activity and the aspect ratio of the filler. Examples are given from tire compounds and from technical rubber goods.Advantages of the functionalization of fillers and the polymers are also presented. The importance of wet compounding is shown in dynamic and ultimate properties. In contrast, carbon nanotubes can form hybrid systems with carbon black or silica are suitable for special applications like anisometric orientations, increase of tear energy, and reducing cut growth resistance off the compound. Exfoliated layered silica gives excellent barrier properties.

    In plastics technology, a wide variety of computer programs are used for the design and optimization of molded plastic parts and for mold design. These programs calculate the filling process, the holding pressure phase, and the cooling phase of the molded part in the mold. The results include, for example, pressures, temperatures, weld/knit lines, and voids. The shrinkage and warpage behavior of the molded part can also be predicted. Understanding and interpreting these simulation results is not trivial, although they are colorful representations with numerical values. Regardless of whether one has many years of experience as a designer, a mold maker, or an injection molder, or whether one is in training or studying, simulation is becoming increasingly important. For this reason, experts who know how to use these programs correctly are increasingly sought after in the market.This book is intended to expand readers' specialist knowledge in the field of simulation, thereby increasing their ability to recognize and avoid molding errors at an early stage. Readers will also learn to draw the right conclusions from the simulation results and develop their own solutions.

    "Energy in Plastics Technology" provides, unlike any other book, the necessary fundamentals for dealing with thermotechnical issues in the processing of plastics, leading to efficient, robust, reliable, economical, and environmentally friendly processes for high-quality products. The following four areas are addressed: - Methodical application of the essential fundamentals to practical problems. The focus is on the formulation of energy balances.- Special emphasis is placed on the understanding of the first and second laws of thermodynamics, with their manifold implications.- Access to key advanced technical literature, which can be highly theoretical, and forms the basis for advanced simulation methods, is provided.- Analytical approaches for modeling processes (as opposed to numerical simulation methods) are covered, so that the influence of the essential process parameters can be better recognized, and correct results in terms of order of magnitude are obtained with reasonable effort. These simplified considerations provide a valuable support for the preparation of experiments and numerical simulations and their critical evaluation. The fundamentals provided are applied - in exemplary calculation examples - to problems relevant to practice in the most important processing and forming methods. The book is aimed at engineers and students working in plastics technology as well as technicians and plastics technologists. Contents:Part 1 - Introductory Fundamentals: Introduction, Material Behavior of Plastics, Thermodynamics, Fluid Mechanics I, Heat TransferPart 2 - Advanced Fundamentals: Steady-State Heat Conduction, Transient Heat Conduction, Thermodynamics of Air-Drying, Fluid Mechanics II, Recycling of PlasticsPart 3 - Practical Examples

    This book offers a unique overview of usage of biomass, biomaterials, and bioproducts, including biopolymers. Included are materials, processes, usage as an energy source, and, in particular, applications. It is intended to educate both professionals and graduate students, who typically must acquire knowledge outside of traditional academic disciplines to gain an appreciation of these systems.While the growing need for renewable energy can be satisfied from other renewable sources, biomass is our only real source of renewable carbon-based chemicals and fuels. More and more companies are moving toward using these materials, and investing in new technology based on renewable resources to develop their businesses in a sustainable way.Despite this, few scientists and engineers have been appropriately trained to work in the interdisciplinary field of the biomass economy. Traditional academic disciplines are not well organized to train engineers and scientists to develop new bio-refinery concepts and bio-based products (including bio-based polymers) in industry, nor to develop and integrate pathways to convert biomass into other forms of energy and useful products. The integration of old and new pathways to satisfy global and local markets is the basic skill required to create new biomass processing alternatives. This book is written to fill this gap.

    Measurement uncertainty is an important component of modern materials analysis: it indicates the boundaries within which the test results can be trusted. Such results are necessary for understanding of, for example, material and product tolerances and lifetimes, vital for plastic product reliability and safety.Determination of measurement uncertainty is normally quite laborious, but this book shows how the available interlaboratory test data for plastics can be used to calculate measurement uncertainty much more simply. It contains many interlaboratory test results in the fields of thermoanalysis, molar mass determination, and quantitative analysis of the composition of material, presented in tables and graphical charts, discussed in the text, and elaborated by practical examples.In addition to the evaluation by means of the presented data (top-down approach), the relationship to the bottom-up approach specified in the Guide to the Expression of Uncertainty in Measurement (GUM) is explained based on an example. Further sections deal with sampling, and the issue of whether or not the difference between analytical results is significant.

    Single-screw or twin-screw extruder? When the need to produce a homogenous polymer melt occurs in the industrial environment, both product attributes and equipment cost must be evaluated. For many applications both the single and twin-screw extruder will produce the desired homogeneous melt needed to form the product through an extrusion die. Some applications such as dispersive mixing of solids in a polymer matrix are best accomplished in a twin-screw extruder. On the other hand, applications involving chemical reactions, color concentrate distributive mixing, and in line polymer-polymer distributive mixing can be accomplished with either device.However, for the same production rate, twin-screw extruders are generally more expensive than single-screw extruders with a diameter less than 200 mm. Therefore, a thorough understanding is needed for the concepts of solids conveying, melting, and mixing for the two types of extruders to make appropriate process acquisition decisions. This book covers engineering and technology concepts that should aid the practitioner in comparing these two types of extrusion equipment relative to process requirements.
