SummaryThis article presents the results of advances made with the material polymethylmethacrylate thathave led to improved chemicaland physical properties. Acrylicresins with a defined mixing pow- der/liquid ratio of up to 10:3(instead of the existing 10:5 to10:7 by weight) have successfully ...
Thanks to its optical clarity, ease of sterilization, moldability, and chemical resistance, PMMA is becoming increasingly popular in the healthcare & medical sector in addition to being used for a variety of other purposes. It is used to produce dental materials, lenses, and surgical equipment....
The purpose of this study was to develop a rapid and green method for the synthesis of lignocelluloses-based materials with superior mechanical properties. Samples were produced by hot-pressed method using different concentrations of CaCO3 and poly (meth
