Book Synopsis Biobased Polyols for Industrial Polymers by : Deny Kyriacos
Download or read book Biobased Polyols for Industrial Polymers written by Deny Kyriacos and published by John Wiley & Sons. This book was released on 2020-03-17 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The replacement of polyols synthesized from petrochemical by polyols originating from natural products, notably from vegetable oils and animal fats, has been the subject of research projects for a number of decades. Very recently, however, the polymers industry has intensified its efforts to include the “green products”, such as biobased polyols, in applications already available in the market. Examples of such applications include polyurethane foams, elastomers and epoxides. This book describes the extraction of the natural constituents of several fruits and plants as well as their chemical conversion to polyols. In addition to the chemistry involved in the process, particular emphasis is attributed to their applications.
Book Synopsis Aspects of Polyurethanes by : Faris Yılmaz
Download or read book Aspects of Polyurethanes written by Faris Yılmaz and published by BoD – Books on Demand. This book was released on 2017-09-27 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications. During World War II, a widespread use of polyurethanes was first seen, when they were used as a replacement for rubber, which at that time was expensive and hard to obtain. During the war, other applications were developed, largely involving coatings of different kinds, from airplane finishes to resistant clothing. Subsequent decades saw many further developments and today we are surrounded by polyurethane applications in every aspect of our everyday lives. While polyurethane is a product that most people are not overly familiar with, as it is generally "hidden" behind covers or surfaces made of other materials, it would be hard to imagine life without polyurethanes.
Book Synopsis Synthesis and Characterization of Bio-based Polyurethanes by : Kelly Stark
Download or read book Synthesis and Characterization of Bio-based Polyurethanes written by Kelly Stark and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Hybrid polyurethanes are commonly made by reacting two chemical building blocks: a polyol and diisocyanate, followed by end-capping with appropriately functionalized silanes to permit moisture curing. This project aims to provide a framework to fully characterize an industrial sealant resin, before incorporating bio-based polyols and isocyanates into the original formulation. The original formulation is derived from petroleum-based monomers. By substituting bio-based molecules in the place of both building blocks, the resulting commercial product will have a higher renewable content. In recent years, finding bio-based alternatives for petroleum products has become a focus of research and industrial efforts in order to decrease petroleum consumption. The industrial partner’s (Adfast Corp.) original product was replicated on a small scale and benchmarks for the molecular weight, viscosity, and stress-strain properties were determined. Gel permeation chromatography (GPC) was used to evaluate and compare the molecular weight distributions of multiple resins. Knowing the molecular weight distribution permitted the elucidation of the relationship between the molar ratio of diisocyanate to polyol in terms of chain length (dimer, trimer formation etc.). Once the original resin was fully characterized, three different bio-based polyols were selected and substituted in place of the original petroleum-based polyol. These new formulations were tested in the same manner as the original formulation, and the molecular weight distributions, viscosities, and stress-strain properties were compared. Of the three polyurethanes produced using bio-based polyols, one, using the commercial MyrinolTM DG-110 polyester polyol, showed promising physical properties: having high elasticity and tensile strength. This formula was then further optimized by the incorporation of a bio-based isocyanate: L-lysine diisocyanate. The properties of this final resin were measured and compared to the original petroleum-based product. It was found that by incorporating the bio-based isocyanate, the physical properties of the PU became more similar to Adfast’s original resin. With additional testing (scale-up, adhesion testing, UV stability etc.) and optimization there is potential to have partial and fully bio-based polyurethanes incorporated into Adfast’s product line. This project has opened doors for Adfast and McGill to pursue different avenues in order to develop a competitive, commercial bio-sourced product"--

Download or read book Production and Characterization of Bio-based Polyols and Polyurethanes from Biodiesel-derived Crude Glycerol and Lignocellulosic Biomass written by Shengjun Hu and published by . This book was released on 2013 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of polyols and PU produced in this study compare well to their analogs derived from petrochemical-solvent based liquefaction processes. Furthermore, crude glycerol alone also has the potential to produce bio-based polyol and PU. The optimization of crude glycerol composition and polyol production processes are crucial to the success of crude glycerol-based polyol production.

Book Synopsis Biopolymers and Biotech Admixtures for Eco-Efficient Construction Materials by : Fernando Pacheco-Torgal
Download or read book Biopolymers and Biotech Admixtures for Eco-Efficient Construction Materials written by Fernando Pacheco-Torgal and published by Woodhead Publishing. This book was released on 2016-01-11 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1930 more than 100,000 new chemical compounds have been developed and insufficient information exists on the health assessment of 95 percent of these chemicals in which a relevant percentage are used in construction products. For instance Portland cement concrete, the most used material on the Planet (10.000 million tons/year that in the next 40 years will increase around 100 %) currently used in around 15% of total concrete production contains chemicals used to modify their properties, either in the fresh or hardened state. Biopolymers are materials that are developed from natural resources. They reduce dependence on fossil fuels and reduce carbon dioxide emissions. There is a worldwide demand to replace petroleum-based materials with renewable resources. Currently bio-admixtures represent just a small fraction of the chemical admixtures market (around 20%) but with environmental awareness for constituents in construction materials generally growing (the Construction Products Regulation is being enforced in Europe since 2013), the trend towards bio-admixtures is expected to continue. This book provides an updated state-of-the-art review on biopolymers and their influence and use as admixtures in the development of eco-efficient construction materials. Provides essential knowledge for researchers and producers working on the development of biopolymer-modified construction materials Discusses the various types of biopolymers currently available, their different production techniques, their use as bio-admixtures in concretes and mortars and applications in other areas of civil engineering such as soil stability, wood preservation, adhesives and coatings All contributions are made from leading researchers, who have intensive involvement in the design and use of biopolymers in construction materials
