Practical Guide to the Assessment of the Useful Life of Plastics
After price and delivery time, the most frequently asked question about a product is 'How long will it last?' Lifetime expectancy is often many years, the service conditions may be complex, and there is a scarcity of definitive data on durability. The situation is complicated by the fact that there are a vast number of degradation agents, service conditions, properties of importance and different plastics.
There are many inherent difficulties in designing durability tests. In many cases, the time scale involved is such that accelerated test conditions are essential. Whilst large amounts of durability data are generated by accelerated methods, much of it is only useful for quality control purposes and relatively little has been validated as being realistically capable of representing service.
Most assessments of the lifetime of plastics are made by considering some measure of performance, such as impact strength, and specifying some lower limit for the property, which is taken as the endpoint. Lifetime is not necessarily measured in time. For example, for some products, it will be thought of as the number of cycles of use.
The object of this publication is to provide practical guidance on assessing the useful service life of plastics. It describes test procedures and extrapolation techniques together with the inherent limitations and problems. The Guide aims to make available the wealth of information that can be applied to help maximise the effectiveness of a durability-testing programme.
This guide seeks to be comprehensive but concentrates on the most common environmental effects causing degradation. The test procedures used are outlined and the relevant textbooks and international standards are well referenced. Examples of lifetime testing studies are cited.
This book will be useful for anyone responsible for designing, manufacturing or testing plastic components. It will also be of benefit to suppliers and users of end products, as an assessment of useful lifetime is critical to the economics and safety aspects of any component.

The use of thermosets dates back over 100 years to the advent of phenolics. Today, a large range of different reactive chemicals is used in the synthesis of these resins. Common thermoset systems include phenol-formaldehyde, melamine-formaldehyde, urea-formaldehyde, resorcinol-formaldehyde, epoxy, polyurethane, polyalkyd, silicone, polyester, acrylic, furan, and polyimide. \u003cbr\u003e\u003cbr\u003eA variety of additives are found in thermosets. Plasticizer-type compounds are used to promote the flow of high viscosity compounds such as epoxy resins. Particulate fillers are used to reduce cost or improve properties and fibrous materials for increased strength and rigidity. Other additives include anti-degradants, curing agents (hardeners and accelerators), flame retardants and lubricants. \u003cbr\u003e\u003cbr\u003eThermosets are used in a wide range of applications from moldings and composites to adhesives. Analysis of thermosets is carried out to determine the reasons for failure, for quality control, to measure residual monomer, to detect contaminants, to monitor the extent of cure and for deformulation. Materials based on thermosets present the analyst with considerable challenges due to their complexity and the wide range of polymer types and additives available. The author of this review has many years of experience in the Polymer Analysis division at Rapra Technology Limited. He has a practical understanding of the usefulness and feasibility of the many techniques on offer to the chemist. \u003cbr\u003e\u003cbr\u003eWet chemistry techniques were mainly used historically. One example is the spectrophotometric titration of epoxy groups using a halogen acid and 2,4-dinitrobenzene sulfonate as the chromophore. \u003cbr\u003e\u003cbr\u003eSpectroscopic techniques include infrared spectroscopy, ultraviolet, nuclear magnetic resonance, atomic absorption, X-ray fluorescence and Raman spectroscopy. \u003cbr\u003e\u003cbr\u003eChromatographic techniques include gas chromatography-mass spectrometry, HPLC, liquid chromatography-mass spectrometry, gel permeation chromatography, thin layer chromatography and supercritical fluid chromatography. \u003cbr\u003e\u003cbr\u003eThermal techniques used to analyze thermosets include differential scanning calorimetry, dynamic mechanical thermal analysis, thermal mechanical analysis, thermogravimetric analysis and dielectric analysis. \u003cbr\u003e\u003cbr\u003eThere are many other analytical techniques covered in this review, which describes their specific uses and even set up details for some analytical techniques. The references at the end of the report describe many specific instances of the analysis of thermoset materials published over the last 10 years. \u003cbr\u003e\u003cbr\u003eThe review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.

Forrest \u003cbr\u003eISBN 978-1-85957-390-7 \u003cbr\u003e\u003cbr\u003epages 160\n\u003ch5\u003eSummary\u003c\/h5\u003e\nThermosets comprise around 25% of world plastic consumption. The use of thermosets dates back over 100 years to the advent of phenolics. Today, a large range of different reactive chemicals is used in the synthesis of these resins. Common thermoset systems include phenol-formaldehyde, melamine-formaldehyde, urea-formaldehyde, resorcinol-formaldehyde, epoxy, polyurethane, polyalkyd, silicone, polyester, acrylic, furan, and polyimide. \u003cbr\u003e\u003cbr\u003eA variety of additives are found in thermosets. Plasticizer-type compounds are used to promote the flow of high viscosity compounds such as epoxy resins. Particulate fillers are used to reduce cost or improve properties and fibrous materials for increased strength and rigidity. Other additives include anti-degradants, curing agents (hardeners and accelerators), flame retardants and lubricants. \u003cbr\u003e\u003cbr\u003eThermosets are used in a wide range of applications from moldings and composites to adhesives. Analysis of thermosets is carried out to determine the reasons for failure, for quality control, to measure residual monomer, to detect contaminants, to monitor the extent of cure and for deformulation. Materials based on thermosets present the analyst with considerable challenges due to their complexity and the wide range of polymer types and additives available. The author of this review has many years of experience in the Polymer Analysis division at Rapra Technology Limited. He has a practical understanding of the usefulness and feasibility of the many techniques on offer to the chemist. \u003cbr\u003e\u003cbr\u003eWet chemistry techniques were mainly used historically. One example is the spectrophotometric titration of epoxy groups using a halogen acid and 2,4-dinitrobenzene sulfonate as the chromophore. \u003cbr\u003e\u003cbr\u003eSpectroscopic techniques include infrared spectroscopy, ultraviolet, nuclear magnetic resonance, atomic absorption, X-ray fluorescence and Raman spectroscopy. \u003cbr\u003e\u003cbr\u003eChromatographic techniques include gas chromatography-mass spectrometry, HPLC, liquid chromatography-mass spectrometry, gel permeation chromatography, thin layer chromatography and supercritical fluid chromatography. \u003cbr\u003e\u003cbr\u003eThermal techniques used to analyze thermosets include differential scanning calorimetry, dynamic mechanical thermal analysis, thermal mechanical analysis, thermogravimetric analysis and dielectric analysis. \u003cbr\u003e\u003cbr\u003eThere are many other analytical techniques covered in this review, which describes their specific uses and even set up details for some analytical techniques. The references at the end of the report describe many specific instances of the analysis of thermoset materials published over the last 10 years. \u003cbr\u003e\u003cbr\u003eThe review is accompanied by around 400 abstracts from papers and books in the Rapra Polymer Library database, to facilitate further reading on this subject.
