Evaluation of alternative polymer bracket materials.
INTRODUCTION Polymer brackets still have some disadvantages because of decreased wear resistance and hardness. The aim of this study was to investigate the mechanical properties of alternative bracket polymers; urethane-dimethacrylate, high-density polyethylene, and an experimental bracket polymer (EBP) consisting of polyethylene and a copolymer were tested. Polycarbonate and polyoxymethylene b...
متن کاملProgress in Durability Study of FRP Materials
During the past decades, FRP strengthened RC structures have attracted worldwide interest in both application and research. Nowadays, as more and more infrastructures are being suffered from severe corrosions due to harsh and extreme environments, the durability of FRP strengthened RC structures has generally emerged as the most important issue in research. Thus, the paper presents the latest p...

متن کاملFundamental Investigations of Durability at a Polymer Electrolyte - Electrode Interface
(1) Understanding the role of peroxide lead free radical attack on the polymer electrolyte at the interface with both anode and cathode electrodes using a specially designed PEM cell enabling accelerated degradation conditions simulating practical H2/Air PEM operation. In this effort the correlation was made with peroxide yield measured directly using RRDE methods with concomitant degradation o...
متن کاملChemical Recycling of Polymer Materials
After the first life cycle of plastics various recycling processes are available for further utilization of these valuable materials. For an ecologically and economically satisfying solution the most suitable process has to be chosen. In chemical recycling polymers are degraded to basic chemical substances which can be reused in the petrochemical industry. For soiled waste plastics or waste pla...
