Book Description
Additives for Polyolefins is a unique quick-reference resource for those who create or use polyethylene and polypropylene compounds—the most commercially important family of plastic materials, making up close to half of the volume all plastics produced and used. These polymers would be useless without various additives. The book focuses on polyolefin additives that are currently important in the plastics industry, alongside new additives of increasing interest, such as nanofillers and environmentally sustainable materials. As much as possible, each chapter emphasises the performance of the additives in the polymer, and the value each relevant additive brings to polypropylene or polyethylene. Where possible, similar additives are compared by capability and relative cost. In this new edition, product tables have been updated with the most current product and company names, new case studies have been added, the role of nanofillers is discussed in greater detail, and the book concludes with a discussion on blending and handling additives, along with an entirely new chapter on how engineers can approach the issue of sustainability when choosing an additive. - Assesses capabilities and costs of a range of additives to enable engineers and scientists to make the correct selection for their property requirements - Provides concise, practical information about the purpose and use of specific additives, fillers, and reinforcements – demystifying the world of additives by providing clear, engineering explanations, and including real-world application case stories - Updated to include additional material on nanofillers, blending and handling, and sustainability

Book Description
This Practical Guide to Injection Moulding is based on course material used by ARBURG in training operators of injection moulding machines. It comes from many years of experience in this field and has been edited by an expert injection moulder at Warwick University. It will be of use to experts looking to fill gaps in their knowledge base and to those new to the industry. The factors involved in injection moulding, from material properties and selection to troubleshooting faults, are all examined in this book. It covers the equipment types in use and machine settings for different types of plastics. Material flow is critical in moulding and there are sections covering rheology and viscosity. High temperature can lead to poor quality mouldings due to material degradation and this is discussed. There are an exceptional number of figures in this text, with many photographs of machinery and mouldings to illustrate key points. There are also numerous tables listing key properties and processing parameters. Flow charts are included in the chapter on troubleshooting to indicate what can be changed to resolve common problems. Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastics materials has moved to the East. Thus Western manufacturers have moved into more technically difficult products and mouldings to provide more added value and maintain market share. Technology is becoming more critical, together with innovation and quality control. There is a chapter on advanced processing in injection moulding covering multi-material and assisted moulding technologies. This Guide will assist progress in developing good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace.

Book Description
Antimicrobial packaging systems are those that beneficially interact with the food or with the surrounding environment, inhibiting microorganism growth or reducing their counts to improve the quality and extend the shelf-life of industrially produced foods. They have undoubtedly become a fully accepted alternative to the direct addition of preservatives to foods, with excellent future prospects.This book will help develop a working knowledge and understanding of antimicrobial packaging, it includes a description of the antimicrobial agents most commonly used and their mechanisms of action, the manufacturing methods available to fabricate the active system, the critical parameters to make an effective product and the tools to optimise them, and the various in vitro and in vivo methods for measuring the goodness of the antimicrobial system for validation purposes.The reader will develop the ability to understand why a specific agent is selected for a particular food product, or why a specific polymeric material and manufacturing technology are chosen. The reader will also become familiar with the different procedures for improving the activity of the packaging solution that is being developed and ways of testing its efficacy. This will accelerate the formulation of the active packaging concept, reducing development-time with respect to the trial and error processes common in many literature reports. Finally, it will help to identify the best and most cost-effective solutions. This volume is intended to be a practical guide to antimicrobial packaging and a quick reference for students and researchers from both academia and industry.
