Annealing process of PS&PP ??

May 20, 2005 1 Replies

Hi, To relieve the residual stress, I will have to thermal anneal my PS&PP panels. At the same time, I want to keep the original geometry shape untouched, i.e. still a good flat panel. I never done this before. Could anyone here tell me the right process to conduct it? e.g. What temperature, how long etc. Or, is there standard for annealing process, where can I find it?



Thanks a lot!



BTW This is for thesis, there is only small amount of them.

Do not anneal they by sticking them near a Bonfire, as it may collapse and injure you. See
