The paper reports the results obtained in the course of the analysis of a failed silane modified polyether (SMP) sealant. The sealant was applied in the socket area to prevent leakage of old cast iron drinking water pipes. It failed after a lifetime in service of 2 years. The investigations by means of thermogravimetric analysis (TGA), dynamic scanning… (More)
A 74-year-old man who had a weight loss of 7 kg in three months, with fever up to 38 degrees C and anaemia (Hb 9.4 g/dl) began to have pain and blue discoloration of fingers II-V of the right hand. Echocardiography demonstrated vegetation on the aortic valve cusps and blood culture grew Aspergillus fumigatus, indicating Aspergillus endocarditis. There were… (More)
To develop a matched sealing material for socket rehabilitation of grey cast iron pipes, an epoxy resin is modified by the addition of different components to improve the flexibility. Three different modifications are made by adding ethylene-propylene diene monomer (EPDM) rubber powder, reactive liquid polymer (ATBN) and epoxidized modifier. In this paper… (More)
In the present study the influence of the molar mass on thermal and mechanical properties is investigated on different grades of POM (Hostaform® resins). A linear relationship between the Melt Volume Rate (MVR) and the crystallinity was found with the exception of one grade. However, the molar mass did not clearly influence other investigated properties.
