Available in PDF, EPUB and Kindle. Book excerpt: Recycling of Polyurethane Foams introduces the main degradation/depolymerization processes and pathways of polyurethane foam materials, focusing on industrial case studies and academic reviews from recent research and development projects. The book can aid practitioners in understanding the basis of polymer degradation and its relationship with industrial processes, which can be of substantial value to industrial complexes the world over. The main pathways of polymer recycling via different routes and industrial schemes are detailed, covering all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials that are then compared with depolymerization approaches. The book examines life cycle assessment and cost analysis associated with polyurethane foams waste management, showing the potential of various techniques. This book will help academics and researchers identify and improve on current depolymerization processes, and it will help industry sustainability professionals choose the appropriate approach for their own waste management systems, thus minimizing the costs and environmental impact of their PU-based end products. Offers a comprehensive review of all polyurethane foam recycling processes, including both chemical and mechanical approaches Assesses the potential of each recycling process Helps industry-based practitioners decide which approach to take to minimize the cost and environmental impact of their end product Enables academics and researchers to identify and improve upon current processes of degradation and depolymerization

Available in PDF, EPUB and Kindle. Book excerpt: This reference, in its second edition, contains more than 7,500 polymeric material terms, including the names of chemicals, processes, formulae, and analytical methods that are used frequently in the polymer and engineering fields. In view of the evolving partnership between physical and life sciences, this title includes an appendix of biochemical and microbiological terms (thus offering previously unpublished material, distinct from all competitors.) Each succinct entry offers a broadly accessible definition as well as cross-references to related terms. Where appropriate to enhance clarity further, the volume's definitions may also offer equations, chemical structures, and other figures. The new interactive software facilitates easy access to a large database of chemical structures (2D/3D-view), audio files for pronunciation, polymer science equations and many more.

Download or read book Preparation of Rigid Polyurethane Foams Catalyzed by Delayed Action Catalyst Derived from Copper-amine Complexes and Carboxylic Acid written by Koatchapan Nimaboot and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, a delayed action catalyst system is used in the preparation of rigid polyurethane foams. The delayed action catalysts were synthesized from reaction between copper-amine complexes and carboxylic acids in ethylene glycol as a solvent to give the salts of copper-amine complex and carboxylic acid. Copper-amine complexes used in this study were Cu(OAc)2(en)2 and Cu(OAc)2(trien) (where en = ethylenediamine and trien = triethylenetetramine). Carboxylic acids used were salicylic acid (Sal) and acetic acid (Ac). Copper-amine complex/carboxylic acid salts, namely Cu(OAc)2(en)2/Sal, Cu(OAc)2(en)2/Ac and Cu(OAc)2(trien)/Sal were studied. UV-Visible spectroscopy and IR spectroscopy were used to characterize the structure of copper-amine complex/salicylic acid salts. The reaction times in the foam formation, physical and mechanical properties of foams are studied. When only copper-amine complex was used as a catalyst, the foam formation was fast. However, there was a problem with the fast gel time which resulted in difficulty in the foam processing. This problem could be solved by using copper-amine complexes/carboxylic acid salts as catalysts, which gave longer gel time while the tack free time was not too long. Cu(OAc)2(en)2/Sal and Cu(OAc)2(trien)/Sal at the mole ratios of 1:1 and 1:0.5, respectively were suitable catalysts, which had gel time about 60 seconds while tack free time was not too slow when compared with commercial catalyst (DMCHA). The gel time of 60 sec was long enough for pouring the mixture of foam formulation into a mold.
