Available in PDF, EPUB and Kindle. Book excerpt: Thermoplastic elastomers (TPEs), commonly known as thermoplastic rubbers, are a category of copolymers having thermoplastic and elastomeric characteristics. A TPE is a rubbery material with properties very close to those of conventional vulcanized rubber at normal conditions. It can be processed in a molten state even at elevated temperatures. TPEs show advantages typical of both rubbery materials and plastic materials. TPEs are a class of polymers bridging between the service properties of elastomers and the processing properties of thermoplastics. Nowadays, the best use of thermoplastics is in the field of biomedical applications, starting from artificial skin to many of the artificial human body parts. Apart from these, thermoplastic elastomers are being used for drug encapsulation purposes, and since they are biocompatible in many cases, their scope of applications has been broadened in the biotechnological field as well. The present book highlights many biological and biomedical applications of TPEs from which the broader area readers will benefit.

This book was released on 2018-04-20 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthetic resin is typically manufactured using a chemical polymerization process. This process then results in the creation of polymers that are more stable and homogeneous than naturally occurring resin. Since they are more stable and are cheaper, various forms of synthetic resin are used in a variety of products such as plastics, paints, varnishes, and textiles. There are various kinds of synthetic resins; acetal resins, amino resins, casein resins, epoxy resins, hydrocarbon resins, polyamide resins, etc. The classic variety is epoxy resin, manufactured through polymerization, used as a thermoset polymer for adhesives and composites. Epoxy resin is two times stronger than concrete, seamless and waterproof. Polyamide resin is another example of synthetic resins. Polyamide resins are products of polymerization of an amino acid or the condensation of a diamine with a dicarboxylic acid. They are used for fibers, bristles, bearings, gears, molded objects, coatings, and adhesives. The term nylon formerly referred specifically to synthetic polyamides as a class. Because of many applications in mechanical engineering, nylons are considered engineering plastics. Resins are valued for their chemical properties and associated uses, such as the production of varnishes, adhesives, lacquers, paints, rubber and pharmaceutical uses. The applications of synthetic resins are seen in some important industries like paint industry, adhesive industry, the printing ink industry, the textile industry, the leather industry, the floor polish, paper, agricultural industry etc. As it can be seen that there is an enormous scope of application of resins hence it is one of the major field to venture. Synthetic Resins are materials with properties similar to natural plant resins. They are viscous liquids capable of hardening permanently. Chemically they are very different from resinous compounds secreted by plants. Synthetic resins are of several classes. The growth of the synthetic resins market can be attributed to the high demand from the packaging sector due to favorable properties, including lightweight and ability to act as an excellent barrier, which allows for their usage in applications such as barrier packaging, shrink wraps, and pharmaceutical packaging. The major contents of the book are properties, manufacturing process, formulae of synthetic resins and applications of synthetic resins, derivatives of resins, use of resins in polymer field, alkyd resin technology, epoxy resins, manufacture of polystyrene based ion-exchange, phenol formaldehyde reactions, polycarbonates resins, polyester coating compositions, synthetic rubbers, modification with synthetic resins, water-soluble polymers, cross-linking of water-soluble coatings etc. This book also contains the list of manufacturers and dealers of raw materials, list of Chemical Plant, Photographs of Machinery with Suppliers Contact Details, Sample Plant Layout and Process Flow Chart. The book will be very useful for new entrepreneurs, manufacturers of synthetic resins who can easily extract the relevant formulation and manufacturing process from the book.

Available in PDF, EPUB and Kindle. Book excerpt: INTRODUCTION Esthetic dentistry can be defined as the art and science of dentistry, applied to create or enhance beauty of an individual within functional and physiological limits. Where as cosmetic dentistry is application of the principles of esthetics and certain illusionary principles, performed to signify or enhance beauty of an individual to suit the role he has to play in his day to day life or otherwise. Appearance is closely linked to social acceptance and professional success. No longer are people satisfied with just looking good, it must be coupled with a complete feeling of total well-being. Newer technologies are being harnessed for this purpose and advanced research is being undertaken. Thus, focus of dentistry in the present times is not only on prevention and treatment of disease but also on meeting the demands for better esthetics. Newer dental materials developed for esthetic enhancement are now chosen for their excellent mechanical as well as esthetic qualities. Esthetic dentistry is emerging as one of the most progressive and challenging branches of this field. Thus dentistry has evolved from a curative to a creative science in a very short span. The modern history of esthetic restorative materials was started with silicate cement, introduced by Fletcher in 1878, the principle anterior restorative material of those days. But, silicate cements were discouraged later on because of their poor strength, irritation to pulp tissue and brittleness. Even the nature of its setting and structure were but imperfectly understood. Self curing acrylic resin was introduced to the dental profession in the mid- 1950s. Initially used for the construction of denture bases, acrylic resin has also been used for many other purposes, including denture teeth, temporary restorations, intraoral splints and veneering agents for crowns and bridges. Since their introduction, acrylic based materials have continued to play a major role in restorative and prosthetic dentistry. But they too showed poor physical properties like high polymerization, shrinkage and coefficient of thermal expansion, irritation to pulp and dimensional instability. In attempt to improve their properties, and the potential for greater application of resins came about with the introduction of the bisphenol A and glycidyl methacrylate, or BIS-GMA, system by R Bowen in the early 1960s .

Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2012 in the subject Medicine - Dentistry, grade: 3, University of Mosul, language: English, abstract: Background and Objectives: Polymethyl methacrylate (PMMA) is currently the material of choice for denture base fabrication, that it has the advantages of good pigment wettability, high gloss and so on. Uses of natural stains (amaranth and vanilla) cheap and available in our country instead of the synthetic stains with heat cure acrylic resin denture base material for matching with natural human gingiva. Materials and Methods: Ninety samples were prepared of pink heat cure acrylic resin VertexTM material, fifteen samples with natural additives and seventy five samples with synthetic Vertex acrylic stainTM. The color of samples and gingival color of 24 healthy young participate were measured by Vita Easyshade device then compared between them. Statistical analysis was done by special designed program prepared for this study in Mat lab program 2010 that calculate the color difference between all the measurements that appeared only the (ΔE) that ≤ 6.8. Results: Results showed that (ΔE) ≤ 6.8 between some of natural and synthetic stains matched in relation to color of patients' gingiva, and some natural stains matched the color of the patients' gingiva. Conclusions: The results approved can be using the natural stains vanilla and amaranth instead of the synthetic Vertex acrylic stains that is clinically acceptable compared in relation to patients. Key Words: Natural stains, Vanilla, Amaranth, PMMA.
