The temperature of the wash water in Japan is typically less than that used in Europe. For example, the temperature of the wash water in North America and Japan is typically between about 10 and about 40° C. (e.g., about 20° C.), whereas the temperature of wash water in Europe is typically between about 30 and about 60° C. (e.g., about 40° C.).

Nov 01, 2015 · The monomers were selected to have homopolymer glass transition temperatures significantly above room temperature (74 °C for PTFEMA, 100 °C for PAN, 110 °C for PMMA) so that the material would remain rigid even upon the hydration of the zwitterionic groups. Free radical copolymerization was used due to its robustness and scalability.
