Available in PDF, EPUB and Kindle. Book excerpt: A revised version of this book is now available. The polyethylene industry has been in the midst of major restructuring and rationalization. This has lead to joint ventures and alliances to combine technologies and exploit opportunities to maximize improvements in process productivity, catalyst innovations, and enhancements in extrusion technology and converting. This comprehensive study of the polyethylene film extrusion process describes this technology in detail. In depth descriptions of the manufacturing processes for polyethylene homopolymers and copolymers, including metallocenes, are reviewed. All aspects of machine design with particular emphasis on screws and dies including coextrusion are discussed comprehensively. With computer modeling, the interactions between equipment and polymer are quantified. All aspects of equipment design and polymer features that control melt fracture, interfacial instabilities, gauge control, output and temperature, and cooling of blown and cast film processes are presented quantitatively. This methodology will highlight solutions in troubleshooting for optimum design and operation and the best available polymer and formulation choices. All polyethylene film applications in packaging, agriculture, lamination, and construction, consumer, industrial, and health care are reviewed and discussed in depth.

Download or read book Computational Analysis of Polymer Processing written by J.R.A. Pearson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large, fast, digital computers have been widely used in engineering practice and their use has had a large impact in many fields. Polymer processing is no exception, and there is already a substantial amount of literature describing ways in which processes can be analysed, designed or controlled using the potentialities of modern computers. The emphasis given varies with the application, and most authors tend to quote the results of their calculations rather than describing in any detail the way the calculations were undertaken or the difficulties experienced in carrying them out. We aim to give here as useful and connected an account as we can of a wide class of applications, for the benefit of scientists and engineers who find themselves working on polymer processing problems and feel the need to undertake such calculations. The major application we have in mind is the simulation of the dynamics ofthe various physical phenomena which arise in a polymer process treated as a complex engineering system. This requires that the system be reasonably well represented by a limited number of relatively simple subprocesses whose connections can be clearly identified, that the domi nant physical effects relevant to each subprocess can be well defined in a suitable mathematical form and that the sets of equations and boundary conditions developed to describe the whole system can be successfully discretised and solved numerically.
