Heating and Annealing Temp/Times of PMMA and Polypropylene and

  1. Feb 1, 2012 #1
    The supervisor of my final year physics project has asked me to find the heating and annealing temp/times for PMMA (perspex) and Polypropylene. I've spent a good hour or so looking for them, but I'm not quite sure where to look. I'll be using the PMMA to make a variable-focus lens, and to form the lens i'll be moulding the PMMA between two glass lenses and popping in the oven. I'll be using the Polypropylene as a test run.

    Does anyone have any ideas of what the ideal temperatures and times would be, or websites/journals etc that I could find the information?
