This report provides a review of the development and current understanding of blow moulding technology. The history and technology of blow moulding are reviewed and details are given on the research carried out in order to better understand the fundamental phenomena affecting the different stages of the process, and their interdependence in controlling final part characteristics. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
Technical d104iles are high performance speciality materials. Applications are found in inflatable structures, tents, as reinforcement in composites for construction, as body armour and vehicle protection, in filters, as a base for flexible printed circuits, hose, conveyor belts and tyres. Polymer Enhancement of Technical d104iles examines the potential for these materials. The review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database.
This review describes the production of styrene polymers in detail, including the synthesis of raw materials, polymerisation routes to polystyrene, production of high impact polystyrene and anionic block copolymers. The review also describes the mechanical properties of styrenic polymers, their electrical properties, and their behaviour in fire. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
Degradation reactions grouped under the heading chemical attack include oxidation hydrolysis, halogenation and other reactions. They also include some purely physical interactions between materials and fluids, dominated by the absorption of fluid into the material or vice versa. One particular mechanism described in some detail is acid induced stress corrosion cracking, which is the most frequent cause of premature failure of GRP products, and where the principle degradation reaction is between the fluid and the glass fibres. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
Annotation The review focuses on the use of pharmaceutical polymer for controlled drug delivery applications. Examples of pharmaceutical polymers and the principles of controlled drug delivery are outlined and applications of polymers for controlled drug delivery are described. The field of controlled drug delivery is vast therefore this review aims to provide an overview of the applications of pharmaceutical polymers. The review is accompanied by approximately 250 abstracts taken from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.
Polyolefins have many and varied applications. However, they have very poor bonding properties. This review discusses ways of improving adhesion and bonding. It describes the theories surrounding adhesion of polyolefins and the analysis techniques which have been used to characterise the material surfaces. Methods of enhancing adhesion are then discussed. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.
Liquid crystal polymers (LCPs) have a wide range of uses, from strong engineering plastics to delicate gels for use in liquid crystal (LC) displays. For this reason, it is essential reading for materials scientists, engineers or technologists in industry, as well as research laboratories or academia. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
This Rapra Review Report, Coatings and Inks for Food Contact Materials, has attempted to cover all of the coatings and inks products used in food contact scenarios. In practice, this encompasses an extremely wide range of polymer systems and formulations, and an emphasis has been placed on coatings and inks used in food packaging, as this is usually regarded as representing the most important application category with respect to the potential for migration to occur. In addition to a thorough introduction of the polymers and additives that are used to produce coatings and inks, there are also chapters covering the regulation of these materials, the migration and analytical tests that are performed on them to assess their suitability for food contact applications, the migration data that have been published, and the areas in the field that are receiving the most attention for research and development. The report is accompanied by around 400 abstracts compiled from the Polymer Library, to facilitate further reading on this subject.
This review first discusses mould release and then addresses mould fouling. Significant material and process variables are considered first and then practical guidance on the selection of release agents and surface treatments are addressed. This is followed by advice on mould cleaning and the assessment of mould sticking and mould fouling. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
