This book is devoted to a nontraditional class of materials which are manufactured by the melt-blowing process - i.e. by extrusion of polymer melt followed by fiber stretching with a gas stream. For the first time extensive data on classical and modern modifications of this technology are generalized and a review is given of extrusion head dies and subsidiary equipment. The text examines the structure and main properties of melt-blown materials as conditioned by peculiarities of overheated polymer melt spraying in an oxidizing medium. Information is given about filtering mechanisms and the main types of polymer fibrous filtering materials: electret, magnetic, adsorptional, bactericidic, and about carriers of microorganisms in biofilters. Social and ecological aspects of the application of melt-blown materials are analyzed.

This book is designed to fulfill a dual role. On the one hand it provides a description of the rheological behavior of molten poly mers. On the other, it presents the role of rheology in melt processing operations. The account of rheology emphasises the underlying principles and presents results, but not detailed deriva tions of equations. The processing operations are described qualita tively, and wherever possible the role of rheology is discussed quantitatively. Little emphasis is given to non-rheological aspects of processes, for example, the design of machinery. The audience for which the book is intended is also dual in nature. It includes scientists and engineers whose work in the plastics industry requires some knowledge of aspects of rheology. Examples are the polymer synthetic chemist who is concerned with how a change in molecular weight will affect the melt viscosity and the extrusion engineer who needs to know the effects of a change in molecular weight distribution that might result from thermal degra dation. The audience also includes post-graduate students in polymer science and engineering who wish to acquire a more extensive background in rheology and perhaps become specialists in this area. Especially for the latter audience, references are given to more detailed accounts of specialized topics, such as constitutive relations and process simulations. Thus, the book could serve as a textbook for a graduate level course in polymer rheology, and it has been used for this purpose.

There are also thickness variations that occur on smaller scales, cm to mm. A periodic thickness variation across the width of the ribbon is a common defect observed in our casting, referred to as the cross-wave defect. The molten metal puddle is subject to capillary vibrations. We find that these oscillations correspond to the cross-wave defect.

We analytically study the influence of convection caused by horizontal heat transfer through the sides of a vertical Bridgman apparatus. We consider the case when the heat transfer across the side walls is small so that the resulting interfacial deformation and fluid velocities are also small. This allows us to linearize the Navier-Stokes equations and express the interfacial conditions about a planar interface through a Taylor expansion. Using a no tangential stress conditions on the side walls, asymptotic expressions for both the interfacial slope and radial segregation at the crystal-melt interface are obtained in closed form in the limit of large thermal Rayleigh number. It is suggested that these can be reduced by appropriately controlling a specific heat transfer property at the edge of the insulation zone in the solid side.

This is the first book published with recipes, methodology and tips on how to make Melt and Pour Soap from Scratch. It is written from the perspective of a Cosmetic Formulator on the production of the popular cosmetic base known as, Melt and Pour Soap. Whether you are a crafter, hobbyist or business owner this book has everything that you need. This book give you guidance on how, as a small home based business, you can follow the regulations, labeling laws and industry standards for selling soap and cosmetics. My entire journey into the cosmetic industry started with Melt and Pour Soap shortly after I discovered aromatherapy. The roots of our business, Essential Wholesale, all started in December of 1998. Over the years we moved from our home kitchenette to a 600 square foot space, to a 2500 square foot building, to a 10,000 square foot space in a bigger building, and from there we have expanded into 30,000 square feet of that same building. In 2011 our business will be moving to an even larger 58,000 square foot building. As our business expanded we began to focus on natural cosmetics and personal care products. However, I never lost my curiosity and fascination with Melt and Pour Soap. Our relationship with Melt and Pour Soap changed over the years. At first we sold retail customized Melt and Pour Soaps. We then bought and sold the company Critter Soaps. Later we sold thousands of pounds worth of wholesale Melt and Pour Soap base and eventually discontinued selling Melt and Pour Soap because the price kept rising. At the time Melt and Pour Soap was the only cosmetic base we sold that we didn't manufacture ourselves. It simply didn't make sense to wholesale someone else's base when our business model had changed to selling only the bases we manufactured ourselves. It was at this point in our business that I decided it was time to formulate our own Melt and Pour Soap ourselves. It didn't take long to have working formulas, but at that moment we were using up every inch of space in our 30,000 square foot building. We were bursting at the seams and couldn't accommodate the manufacturing and cooling of the Melt and Pour Soap Base in bulk. Our space was so tight we couldn't possibly cool an 8,000 lb batch of Melt and Pour Soap base into multiple 1 lb, 20 lb and 40 lb blocks to sell in bulk. But we got continued requests to manufacture and sell Melt and Pour Soap base. My solution is this book. I decided to share these basic recipes with you to give you the freedom to make your own Melt and Pour base in the quantities that work best for your business. These recipes will teach you the foundational information that you need and give you tips on how to customize your base.

Polymer nanocomposites have been a keen area of research interest for the past decade. In place of traditional fillers, nanocomposites use significantly smaller amounts of reinforcing material with very high surface area per unit volume. The promise of polymer nanocomposites ranges from improved mechanical strength, reduced thermal expansion, improved barrier properties, decreased flammability, to electrical conductivity, but all of these potential improvements depend on good dispersion of the nanocomposite filler. The goal of this research has been twofold: first, to develop an effective technique in which melt rheology can be used to characterize exfoliation of nanoclay in this important class of materials and to determine the effect that applied stresses have on such polymer nanocomposite systems. To date, the use of melt rheology in characterizing exfoliation in polymer nanocomposites has been limited to qualitative assessment of a solid-like plateau that evolves in the elastic modulus due to the dispersing nanoclay particles forming and acting as a reinforcing network structure typically known as a "house of cards" morphology. By applying scaling laws from fractal gel rheology to linear rheology for polypropylene and polystyrene nanocomposite systems, melt rheology has been used effectively to determine the fractal dimension of the clay network structure in nanocomposites. These scaling laws have also allowed for percolation behavior to be determined for the nanocomposite systems and with it aspect ratios for the particles have been determined. These rheological predictions have shown to prove accurate when compared to direct measurements from X-ray scattering and TEM microscopy analyses. High shear stress mixing regimens have shown to be successful in creating well dispersed polystyrene nanocomposites. For polypropylene nanocomposites, a new blend creation mechanism, multilayer coextrusion has been employed to make thin films of nanocomposite materials. Characterizing the mechanical and thermal properties of these films suggests multilayer coextrusion can be used to create dispersed nanoclay morphologies in polymer melts. This thesis has provided a new and reliable rheological tool for quickly assessing dispersion and has suggested a new multilayer coextrusion technique to make tailored nanomaterials.
